Testing Analog Amplifiers
# check that the DACs can command the Amplifier to control motor speed. Test Console commands like DAC0=200 (with the axis disabled)
# Enable the Servo using the Step Response Screen. Zero, Enable
==Testing Analog Amplifiers==
One way to perform a basic test of an Analog Amplifier to see if it is working and likely capable of being driven by a Kanalog DAC Output is to apply a small voltage to the input to see if the motor drives. A 1.5V battery in series with a 1K Ohm resistor is one possible voltage source. The 1K Ohm resistor should limit the current in case a mistake is made. When applied the motor should drive at a controlled 15% (Speed if the drive is in Velocity mode, or torque if in torque mode). Reversing the battery should reverse the motor direction.
