Stalled rotor protection
Description
If the motor current rises above an adjustable stalled rotor protection level (current
threshold), a defined and delayable response can be configured for SIMOCODE pro. In this
case, for example, the motor can be shut down independently of the overload protection.
The stalled rotor protection is only active after the parameterized class time has elapsed,
e.g. for Class 10 after 10 seconds, and prevents unnecessarily high thermal and mechanical
loads as well as premature aging of the motor.
When the stalled rotor level is exceeded, SIMOCODE pro reacts according to the selected
response.
Level: 0 to 1020 % of l
s
(default: 0).
Note
Rounding
Intermediate values are automatically rounded.
Here you can determine the response to violation of the stalled rotor level:
See also "Tables of responses of SIMOCODE pro" in Chapter Important information
(Page 7) and Table "Responses" in Chapter Motor protection functions (Page 31).
The "Delay" parameter determines the length of time that the stalled rotor level must be
permanently exceeded before SIMOCODE pro executes the desired response. If no setting
is made, there will be no response.
Setting range: 0 to 25.5 s (default: 0.5 s).
