Measures for error diagnosis and/or
corrective action
Additional information and descriptions in
the manual
Check machine parameter
(distance of one motor revolution and
distance for the number of signal periods).
Check the motor table (columns TYPE and
STR).
Check speed encoder.
See "Speed Encoders" on page 18 – 293.
Exchange the motor.
Check the speed encoder cable.
Exchange the motor drive control board.
See "Speed Encoders" on page 18 – 293.
Check the adjustment of the axes.
Check the inverter.
See "Sequence for Finding Errors in the
Control Loop" on page 6 – 62.
See Service Manual Inverter Systems and
Motors.
Install position encoder input.
Check connection of the position encoder
input.
Exchange position encoder input.
See "Position Encoders" on page 18 – 277.
Check the machine parameters for PWM
frequency.
PWM frequency > 5000 Hz only with
suitable hardware and only with PWM
outputs X51, X52, X57 or X58.
PWM frequency <= 5000 Hz must be
identical within the control group.
PWM frequency > 3200 Hz
Check the motor table (column SYS).
Check the speed encoder cable.
Exchange the motor.
Exchange the motor drive control board.
See "Speed Encoders" on page 18 – 293.
Check the software version.
Inform your service agency.
