Parameters for speed limiting
No.
Description
1146
Maximum motor speed (SRM)
Maximum motor speed (ARM)
Maximum motor velocity (SLM)
... specifies the maximum motor speed or maximum motor velocity defined by the motor
manufacturer.
Note:
This is only included in the speed limiting for rotary induction motors (ARM).
1147
Speed limit (SRM)
Speed limit (ARM)
Velocity limit, motor (SLM)
... specifies the maximum permissible motor speed or motor velocity.
When commissioning the system for the first time and for "calculate unlisted motors", the param-
eter is pre–assigned as follows:
S
SRM
S
ARM, SLM, PE spindle
Speed actual value > Speed limit
S
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.
1401:8 Speed for max. useful motor speed (SRM,
ARM)
Velocity for max. motor useful velocity
(SLM)
... limits the speed to the maximum useful motor speed.
The parameter is pre–set at the first start–up and for "Calculate unlisted motor":
S
SRM
S
ARM, SLM, PE spindle
Note:
P1401:8 is used for normalization for speed setpoints entered via analog inputs (refer to Chap-
ter 6.6).
1405:8 Monitoring speed, motor (SRM, ARM)
Monitoring velocity, motor (SLM)
... specifies the maximum permissible setpoint as a percentage referred to P1401:8.
The parameter is pre–assigned as follows when the system is commissioned for the first time
and for "calculate unlisted motor":
