Denominator bandwidth > twice the natural frequency
The denominator bandwidth of a current or speed setpoint filter is
greater than twice the natural frequency.
This alarm is only generated for the general bandstop, if the following is
valid:
Speed setpoint filter 1: P1516 > 2 * P1514 or P1520 <> 100.0
Speed setpoint filter 2: P1519 > 0.0 or P1521 <> 100.0
Current setpoint filter 1: P1212 > 0.0
Current setpoint filter 2: P1215 > 0.0
Current setpoint filter 3: P1218 > 0.0
Current setpoint filter 4: P1221 > 0.0
The denominator bandwidth of a current or speed setpoint filter must
be less than twice the natural frequency.
Speed setpoint filter 1: P1515 <= 2 * P1514 * 0.01 * P1520
Speed setpoint filter 2: P1518 <= 2 * P1517 * 0.01 * P1521
Current setpoint filter 1: P1211 <= 2 * P1210
Current setpoint filter 2: P1214 <= 2 * P1213
Current setpoint filter 3: P1217 <= 2 * P1216
Current setpoint filter 4: P1220 <= 2 * P1219

Format error
The calculated bandstop filter coefficients cannot be represented in the
internal format.
Change filter setting.

Induction motor oper.: drive converter frequency
motor \%d not permissible
In induction motor operation (selected by P1465 < P1146), drive con-
verter frequencies of 4 or 8 kHz are permissible.
– Change P1100
– Cancel induction motor operation (P1465 > P1146)

STOP II (SRM, SLM) STOP I (ARM)
Induction motor oper.: speed controller gain, motor
\%d too high
The P gain of the speed controller (P1451) is too high.
For the speed controller, enter a lower value for the P gain (P1451).
