C420 Ctrlr
parameters
incorrect %s
 Feedforward-control parameters are set
incorrectly (acceleration, friction)
 Excessive acceleration
 Controller parameters are set incorrectly
(Ki, Kp, Kd)
 Filters are set incorrectly (band rejection,
low pass)
 Inverter defective (IGBT)
 Incorrect motor selected in motor table
 Check the adjustment of the axis.

C430 Error of
position input
<axis>
 Position encoder input does not exist
 Position encoder input not connected correctly
 Position encoder input defective
 Install position encoder input.
 Check connection of the position encoder
input.
 Exchange the position encoder input.

C440 PWM
frequency <axis>
incorrect
 PWM frequency within a control group is
incorrect.
 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
