C400 Line count
error <axis>
 Line count from the motor table does not
match the downloaded values.
 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.  See “Speed Encoders” on page 18 – 293.
C410 Rotor
position <axis>
undefined
 Contamination of the speed encoder (Zn
track).
 Speed encoder cable defective.
 Motor control board defective.
 Speed encoder defective.
 Exchange the motor.
 Check the speed encoder cable.
 Exchange the motor drive control board.
 See “Speed Encoders” on page 18 – 293.  See “Speed Encoders” on page 18 – 293.
C430 Ctrlr
parameters
incorrect %s
 Feedforward-control parameters are set
incorrectly (acceleration, friction).
 Excessive acceleration.
 Controller parameters are set incorrectly (Ki,
Kp, Kd).
 Filters set incorrectly (band rejection, low
pass).
 Inverter defective (IGBT).
 Incorrect motor selected in motor table.
 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.
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 position encoder input.
 See “Position Encoders” on page 18 – 277.
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 freque
ncy <= 5000 Hz must be
identical within the control group.
 PWM frequency > 3200 Hz
C450 Wrong
encoder <axis>
 Entry in column SYS of the motor table
incorrect.
 Speed encoder cable defective.
 Speed encoder defective.
 Motor control board defective.
 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.  See “Speed Encoders” on page 18 – 293.
C460 Motor
speed too high
<axis>
 Motor not controllable  Check the software version.
 Inform your service agency.
