When commissioning the system for the first time and for ”calculate unlisted motors”, the param-
eter is pre–assigned as follows:
 SRM 1.1  P1400
1.05  P1400 (from SW 7.1 with ”SIMODRIVE 611 universal HR”,
resolver)
 ARM, SLM, PE spindle P1146
Speed actual value > Speed limit
 Exceeded by more than 2 %:
The torque limit when motoring is internally set to zero, the drive is prevented from acceler-
ating any further.
With the appropriate setting, the ”speed controller at its limit” monitoring can respond.

Note:
P1401:8 is used for normalization for speed setpoints entered via analog inputs (refer to Chap-
