Motor changeover only permissible for the closed-loop
speed controlled mode
Cause
Motor changeover (P1013) may only be activated in the closed-loop
speed controlled mode (P0700 = 1).
Remedy
– Inhibit motor changeover (P1013 = 0)
– Change over into the closed-loop speed controlled mode (P0700 = 1)

Speed measuring range is not sufficient
Cause
The maximum speed which can be achieved with speed feedback can-
not be measured using the module.
Remedy
– Parameterize the encoder type corresponding to the type of motor
and the control module.
– Synchronous motor: P1147 * resolver pole pair number must be less
than the limiting frequency of the control module (12 bit: 25402 RPM;
14 bit: 6350 RPM).
Induction motor : min ( P1146, P1465 ) * resolver pole pair number
must be less than the limiting frequency of the control module (12 bit:
25402 RPM; 14 bit: 6350 RPM).

Speed controller gain too high
Cause
P gain, speed controller for the lower speed range (P1407) and the up-
per speed range (1408) were selected to be too high.
Remedy
Reduce the P gain of the speed controller.
Only optimized with the adaption disabled (P1413 = 0). The P gain
(P1407) is then effective over the complete speed range. After the opti-
mum setting has been found, adaption can be re-enabled (P1413 = 1)
and the P gain optimized for the upper speed range (P1408).
