Measures for error diagnosis and/or
corrective action
Additional information and descriptions in
the manual
Check the inverter and wiring.
Check the motor and wiring.
See Service Manual Inverter Systems and
Motors.
Check the motor and wiring.
Check the inverter.
Tighten the conductor bars securely.
See Service Manual Inverter Systems and
Motors.
Check MP110.x/MP111.x
Check the parameter value in MP640.x
(maximum position deviation between MC
and CC during operation).
Check the parameter value in MP720.x
(linear axis error compensation for analog
axes).
Check the parameter value in MP710.x
(backlash compensation).
Check the mounting of the position encoder.
See "Sequence for Finding Errors in the
Control Loop" on page 6 – 62.
