Good afternoon Tom. I follow your instructions, as far as I understand. I have already pointed out the technical data. encoder (digital bar) has a resolution (accuracy). = 0.001 mm. The motor driver has 19,200 pulses per inch (64) = 1.2` / 360 = 300 steps. What information do you provide? I did not understand your last sentence - make sure the settings are correct. show the picture with the correct data. thanks

p/s After pressing the "zero" - "move" button. Position counter starts counting (infinite) axis is STOP!

The motor driver has 19,200 pulses per inch
No. It has 19,200 pulses per revolution.

I'm guessing your lead screw pitch is 0.2 inches/rev ? (You didn't provide this information we requested)

So the step resolution is 19200 / 0.2 = 96000 steps per inch.

Encoder resolution = 1000 counts/mm = 25400 counts per inch.

Input gain = Steps/Count = 96000/25400 = ‭3.77952756

We need to see your Step Response, Configuration, and IIR Screens in KMotion.exe. Not KMotionCNC.

I don't understand MOTOR ON and MOTOR OFF. Sending images or videos without explanation is not helpful.

The Encoder is not working.

1-it is true, correct
2 - not true - + . has 5mm/turn. TBI C3 2005
3 - is not true. At 96000 - making a test run at a distance of 240 mm. I have actual mixing only 237.45 mm. swarms of 97500 - 240 mm
4 - I made the necessary amendments. the encoder works?

Hi Igor,
2 - not true - + . has 5mm/turn. TBI C3 2005
Ok then:

step resolution is 19200steps/rev / (5mm/rev / 25.4mm/inch) = 97536 steps per inch.

Input gain = Steps/Count = 97536/25400 = ‭3.84

Change Input Mode to Encoder to make Encoder work:

Set P Gain to Zero. Set V to Velocity to Move in Steps/Sec. For example to move 0.5 inches/sec put 97536 * 0.5 = 48768

Only Plot: Command, Position, Output Command vs Time (Your drives don't have current or voltage measurements)

Encoder seems bad or picking up noise.

#1 - Set P I D to zero (no feedback)

#2 - Move slowly with low acceleration. V=10000 A=20000 J=200000

#3 - Post a Plot

#4 - describe what the motor does

Good afternoon Tom. During these settings, there are no anomalies in the motor driver operation. Motor shuts in normal mode. Axle is mixed without breaks and any postage noises

PA_06 a pre-emptive co-factor to compensate for the reaction delay occurring in the current control circuits and position
PA_10 retention current in% of the total phase current. Also affects the starting current at start of movement. Large values increase heating while increasing permissible accelerations for the drive = ALL ZERO driver motor.right diagram

Hi Igor,

The Encoder Position looks like garbage. Probably picking up noise from the Stepper Motor wiring. Are you using shielded cables? Test the encoder by moving the axis by hand.
