Positioner does not move.
Cables not connected properly:
■
Check the connecting cables.
For positioners with ActiveDrive™ only:
Check if power supply is connected:
■
Verify that the included MS-500.PS power supply is connected and
turned on.
Positioner or positioner cable is defective:
■
Replace positioner with a working positioner of the same type to test a
new combination of controller and positioner (positioners of a different
type may malfunction due to unsuitable parameter settings on the
controller).
Test cable and / or replace with a working cable of the syme type.
Unusually high friction in the spindle-nut-system:
■
Clean the spindle and add new lubricant.
Wrong command or wrong syntax:
■
Check the error code (with PI-GCS command set, use ERR?; see
controller and software manuals for the error code explanations).
Positioner is not referenced:
■
In the GCS command set, some closed-loop motion commands are
not executed if the mechanics has not been referenced—(ERR?
replies "5", see controller and software manuals). Reference the axis
as described in the controller and user manuals.
Wrong axis commanded:
■
Check if commanded axis is that of the desired positioner.
