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 PositionServo 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 Position mode with master encoder motion source (no program)
Reference voltage input signal source is not properly selected.
In MotionView program check <Parameters> <Reference> set
to <External>
In Position mode using indexing program
Variables ACCEL, DECEL,MAXV, UNITS are not set or set to
0. Before attempting the move set values of motion parameters
ACCEL, DECEL,MAXV, UNITS
Problem
In velocity mode, the motor runs away.
Possible Cause
• Hall sensors or encoder mis-wired.
• PositionServo not programmed for motor connected.
Suggested Solution
• Check Hall sensor and encoder connections.
• Check that the proper motor is selected.
