SimpleServo 100/200 User Manual Rev 3.4

PROBLEM

Diagnostic LED is steady GREEN (enabled status) but motor does not run.

SUGGESTED SOLUTION

• If in torque or velocity mode:

• Reference voltage input signal is not applied.

• Reference signal is not connected to the SimpleServo input properly; connections are open.

• In MotionView program check <Parameters> <Reference> set to <External>

• For Velocity mode only: In Motion View check <Parameters> <Compensation> <Velocity loop

filter> P-gain must be set to value more then 100 in order to run. Without load, motor will run with

P-gain set as low as 20, but may not run under load. If P-gain is set to 0 motor will not run at all.

• In step and direction mode:

• Step and Direction inputs are not wired correctly.

• In MotionView program check <Parameters> <Step input type> is set for <S/D> if you use a step-

and-direction indexer output, and <Master Encoder> if you use quadrature type output from a

master motor encoder or indexer.

• Position loop P-gain set to 0. Set P-gain to 200 and D-gain to 200 initially to get motion. Tune

them afterwards for best performance.

PROBLEM

In velocity mode, the motor runs away.

POSSIBLE CAUSE

• Hall sensors or encoder mis-wired.

• SimpleServo not programmed for the connected motor.
