135
Standstill monitoring has responded
Cause
The drive has left the standstill window (P0326) after the standstill mon-
itoring time (P0325) has expired.
Possible causes are:
– Position actual value inversion (P0231) incorrectly set
– Standstill monitoring time (P0325) parameters too low
– Standstill window (P0326) parameters too low
– Position loop gain (P0200) too low
– Position loop gain (P0200) too high (instability/tendency to oscillate)
– Mechanical overload
– Check connecting cable motor/converter (phase missing, exchanged)
Remedy
Check above parameters and correct.

Conv.factor,feedforward contr.speed,parameter set
\%d,cannot be represented
Cause
The conversion factor in the position controller between velocity and
speed cannot be displayed.
This factor depends on the following parameters:
– Spindle pitch (P0236), for linear axes
– Gearbox ratio (P0238:8/P0237:8).
Remedy
Check the above mentioned parameters and correct.

Conv.factor,pos.contr.output,parameter set \%d,cannot
be represented
Cause
The conversion factor in the position controller between the following
error and the speed setpoint cannot be displayed.
This factor depends on the following parameters:
– Spindle pitch (P0236) (for linear axes)
– Gearbox ratio P0238:8/P0237:8
– Position control loop gain P0200:8
Remedy
Check the above mentioned parameters and correct.

STOP II
138
Conversion factor between the motor and load too
high
Cause
The conversion factor between the motor and load is greater than 2 to
the power of 24 or less than 2 to the power of –24.
Remedy
Check the following parameters and correct:
P0236, P0237, P0238, P1005, P1024
