Problem
Ready LED is on 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 MotionView check <Parameters>
<Compensation><Velocity loop filter> P-gain must be set to
value more then 0 in order to run. Without load motor will run
with P-gain set as low as 20 but under load might not. 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 100 and D-gain to 200
If in PIVFF mode or if in P+V mode P-gain to 10 and D-gain for 5
and Velocity P-gain 50 and I-gain 20 initially to get motion. Tune
them afterwards for best performance.
Problem
In velocity mode, the motor runs away.
Possible Cause
• Hall sensors or encoder miswired.
• SimpleServo not programmed for motor connected.
Suggested Solution
• Check Hall sensor and encoder connections.
• Check that the proper motor is selected..
