3PH<N>=<M> <A>

Description

Sets the assigned PWMs of an axis to the specified magnitude and phase angle for a brushless 3 phase motor.

This command is useful for energizing a coil (or effective coil position). This is often required while initial homing or determining the commutation offset for a 3 phase brushless motor. If an effective coil position is energized, the motor rotor will normally align itself to the coil position. This is similar to the manner in which a stepping motor operates. Since the rotor location is then known, the commutation offset may then be determined. Alternately if an index mark is available, the effective coil position may be rotated by changing the phase angle until the index mark is detected.

Parameters

<N>

Selected Axis for command. Valid range 0...7.

<M>

Magnitude of output to apply.

Valid Range is -230 ... +230 PWM units

<A>

Commutation angle to be used.

Arc <XC> <YC> <RX> <RY> <θ0> <dθ> <Z0> <A0> <B0> <C0> <Z1> <A1> <B1> <C1> <a> <b> <c> <d> <tF>

Description

Place circular (also elliptical or helical) interpolated move into the coordinated motion buffer. See also KMotion Coordinated Motion. A path through space is defined where x and y are changing in an elliptical manner and z, a, b, c are changing in a linear manner forming a portion of a helix. A parametric equation is defined which describes which portion of the path as well as how as a function of time the path is to be traversed. This command can consist of up to 6 axis of coordinated motion. X and Y perform an arc while Z, A, B, and C move linearly.

Although the Arc command may be sent directly, the Arc command is normally generated automatically to perform a planned trajectory by the coordinated motion library or GCode.

(XC,YC) - center of circle

(RX,RY) - x radius and y radius

θ0 - initial angle for the beginning of the path

dθ - amount of angular change for the path

Z0 - initial Z position of path

A0 - initial A position of path

B0 - initial B position of path

C0 - initial C position of path

Z1 - final Z position of path

A1 - final A position of path

B1 - final B position of path

C1 - final C position of path

3rd order parametric equation where
p = a t 3 + b t 2 + c t + d
p is the position along the path as a function of time. When p=0 the (x,y,z) position will be at the beginning of the path (θ= θ0 and z=z0). When p=1 the (x,y,z) position will be at the end of the path (θ= θ0+dθ, and z=z1).

This motion segment will be performed over a time period of tF, where t varies from 0 ... tF. Note that it is not necessary that p vary over the entire range of 0 ... 1. This is often the case when there may be an acceleration, constant velocity, and deceleration phase phase over the path. ie: t might vary from 0.0->0.1 where p might vary from 0.3->0.7.

Parameters

<XC> - X center of ellipse, units are position units of x axis

<YC> - Y center of ellipse, units are position units of y axis

<RX> - X radius of ellipse, units are position units of x axis

<RY> - Y radius of ellipse, units are position units of y axis

<θ0> - initial theta position on ellipse, radians (0 radians points in the +x direction)

<dθ> - change in theta position on ellipse, radians (+ theta causes CCW motion)

<Z0> - initial Z position on path, units are position units of z axis

<A0> - initial A position on path, units are position units of a axis

<B0> - initial B position on path, units are position units of b axis

<C0> - initial C position on path, units are position units of c axis

<a> - parametric equation t3 coefficient

<b> - parametric equation t2 coefficient

<c> - parametric equation t coefficient

<d> - parametric equation constant coefficient

ExecTime

Description

Displays the amount of the Coordinated Motion Buffer that has been already executed in terms of Time. KMotion contains a Coordinated Motion Buffer where move segments (linear and arcs) and I/O commands may be downloaded and executed in real time. This command is useful for determining how long before the Coordinated Motion Buffer will complete. For example, if a number of segments have been downloaded where their total execution time is 10 seconds, and they are currently in progress of being executed, and the ExecTime command reports that 8 seconds worth of segments have been executed, then the remaining time before the queue completes (or starves for data) would be 2 seconds. This command is useful for applications where it is important not to download data too far ahead so changes to the Trajectory may be made. The value returned is a floating point decimal value in Seconds with 3 decimal places. If the Coordinated Motion has already completed the amount of time will be a negative value whose magnitude is the total time that was executed. See also Coordinated Motion.

Displays:

Executed time in seconds as a floating point decimal number with 3 decimal places

C Programs may access this array as the integer array:

persist.UserData[n];

It also resides in the KMotion Persist memory structure so that if memory is flashed, the value will be present at power up.

Description

Place linear (in 6 dimensions) interpolated move into the coordinated motion buffer. See also KMotion Coordinated Motion. A path through space is defined where x, y, z, a, b, and c are changing in a linear manner. A parametric equation is defined which describes which portion of the path as well as how as a function of time the path is to be traversed.

Although the Linear command may be sent directly, the Linear command is normally generated automatically to perform a planned trajectory by the coordinated motion library or GCode.

(X0,Y0,Z0,A0,B0,C0) - beginning of path

(X1,Y1,Z1,A1,B1,C1) - end of path

3rd order parametric equation where
p = a t 3 + b t 2 + c t + d
p is the position along the path as a function of time. When p=0 the (x,y,z,A) position will be at the beginning of the path. When p=1 the (x,y,z,A) position will be at the end of the path.

This motion segment will be performed over a time period of tF, where t varies from 0 ... tF. Note that it is not necessary that p vary over the entire range of 0 ... 1. This is often the case when there may be an acceleration, constant velocity, and deceleration phase over the path. ie: t might vary from 0.0->0.1 where p might vary from 0.3->0.7.

<X0> - X begin point

<Y0> - Y begin point

Description

Place linear (in 8 dimensions) interpolated move into the coordinated motion buffer. See also KMotion Coordinated Motion. A path through space is defined where x, y, z, a, b, c, u and v are changing in a linear manner. A parametric equation is defined which describes which portion of the path as well as how as a function of time the path is to be traversed.

Although the LinearEx command may be sent directly, the LinearEx command is normally generated automatically to perform a planned trajectory by the coordinated motion library or GCode, however currently the GCode Interpreters available only support 6 axes of simultaneous motion.

(X0,Y0,Z0,A0,B0,C 0,U0,V0) - beginning of path

(X1,Y1,Z1,A1,B1,C1,U1,V1) - end of path

3rd order parametric equation where
p = a t 3 + b t 2 + c t + d
p is the position along the path as a function of time. When p=0 the (x,y,z,A) position will be at the beginning of the path. When p=1 the (x,y,z,A) position will be at the end of the path.

This motion segment will be performed over a time period of tF, where t varies from 0 ... tF. Note that it is not necessary that p vary over the entire range of 0 ... 1.

SetFRO <F>

Description

Sets Hardware FRO (Feed Rate Override) in KFLOP which is the rate that the Coordinated Motion Buffer is executed. A value of 1.0 = Normal Feed Rate = real time = an advance of 90us of time every 90us Servo Sample Period.

A negative FRO value will cause the Coordinated Motion Buffer to execute in reverse up until the beginning or until the point where Coordinated Motion Buffer data has been lost due to buffer wrapp ing (MAX_SEGMENTS is currently ~35,000 segments). When approaching the point where previous data was lost, the FRO will be automatically reduced to zero in order to avoid an abrupt stop. This will not occur (and should not be necessary) when approaching the actual beginning of the buffer because normal acceleration from a stop should exist. In this case Time will stop abruptly when the beginning of the buffer is reached.

In order to avoid an instantaneous change in velocity the FRO will be ramped from the current rate to the specified rate. This command uses a default ramp rate that has been determined based on the Max Allowed Velocities, Accelerations, and Jerks of all the currently defined Coordinate Motion System Axes Channels. In order to specify a different rate the SetFROwRate command may be used.

This command will not alter the rate of execution if the FeedHold mechanism is currently in effect. See StopImmediate. However the specified speed will be saved so that if FeedHold is eventually released, the rate will resume to this specified speed. To change the FRO while in FeedHold use the SetFROTemp or SetFROwRateTemp commands instead. Those commands were intended to be used while in Feed Hold and will not alter the rate that will be resumed after Feed Hold is released.

Parameters

<F>

Desired FRO Value. 1.0 corresponds to normal Real Time, 0.0 corresponds to fully stopped, negative values drive time in reverse. Valid range -100...+100

Example

SetFRO 1.2

SetFROTemp <F>

SetRapidFRO <F>

Description

Sets Hardware RFRO (Rapid Feed Rate Override) in KFLOP which is the rate that the Coordinated Motion Buffer is executed. A value of 1.0 = Normal Feed Rate = real time = an advance of 90us of time every 90us Servo Sample Period.

Note: KFLOP Maintain separate Rate Overides for Rapid motion vs normal Feed Motion. Commands (BegRapidBuf and EndRapidBuf) inserted into the Coordinated Motion Buffer determine what type of motion is currently in progress and which Override is to be used.

A negative RFRO value will cause the Coordinated Motion Buffer to execute in reverse up until the beginning or until the point where Coordinated Motion Buffer data has been lost due to buffer wrapp ing (MAX_SEGMENTS is currently ~35,000 segments). When approaching the point where previous data was lost, the RFRO will be automatically reduced to zero in order to avoid an abrupt stop. This will not occur (and should not be necessary) when approaching the actual beginning of the buffer because normal acceleration from a stop should exist. In this case Time will stop abruptly when the beginning of the buffer is reached.
