10. If using a potentiometer for a setpoint, verify its operation as follows:
a. Use the keypad to display the value of the Diagnostics::ANIN 3 (A4).
b. Vary the setpoint potentiometer and observe the input voltage change on the keypad display.
c. Additional Setpoint Inputs may also appear at ANIN 1 (A2) and ANIN 2 (A3).
Verify these if they are installed.
d. The sum of all the setpoints is given by the value of the Speed Setpoint parameter. This can be
verified from the keypad display.
11. Verify External Current Limit settings, if used.
If using a single external clamp, A6 low (0V). Verify ANIN 5 (A6) is +10V or is adjustable up to +10V.
If using dual external clamps, A6 high (+24V). Verify ANIN 5 (A6) is at +10V or is adjustable up to
+10V and that ANIN 4 (A5) is at +10V.
12. Verify speed feedback device, if possible.
a. Analog Tachometer – The voltage at G3 (DC Tach Input) should go positive when shaft is
rotated in the forward direction.
b. Encoder – The ENCODER parameter should give a positive reading when shaft is rotated in the
forward direction. Also check the Speed Feedback parameter is reading a positive value.
13. Set Main Current Limit to 0.00% to limit the motor current.
