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 set to

For Velocity mode only:

In MotionView check
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 set to

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..
