3.9.2 SP-2# Reset Functions
Parameters to configure the trip delay do to Torque Limit or Drive Fault.
SP-24 Trip Delay at Current Limit
Range:
60 s* [0 - 60 s]
SP-25 Trip Delay at Torque Limit
Range:
60 s* [0 - 60 s]
SP-26 Trip Delay at Drive Fault
Range:
0. s* [0 - 35 s]
SP-29 Service Code
Range:
000000* [000000 Hex - FFFFF]
3.9.3 SP-3# Current Limit Ctrl.
Parameters to configure the Current Limit Control which is activated when the motor current, and thus the torque, is higher than the torque limits set in par. F-40
Torque Limiter Driving and F-41 Torque Limiter Braking.
SP-30 Current Lim Ctrl, Proportional Gain
Range:
100 %* [0 - 500 %]
SP-31 Current Lim Ctrl, Integration Time
Range:
0.020 s* [0.002 - 2.000 s]
Function:
Enter the current limit trip delay in seconds. When the output current reaches the current limit (par.
F-43 Current Limit), a warning is triggered. When the current limit warning has been continuously present
for the period specified in this parameter, the frequency converter trips. Disable the trip delay by setting
the parameter to 60 s = OFF. Thermal monitoring of the frequency converter will still remain active.
Function:
Enter the torque limit trip delay in seconds. When the output torque reaches the torque limits (par.
F-40 Torque Limiter (Driving) and par. F-41 Torque Limiter (Braking)), a warning is triggered. When the
torque limit warning has been continuously present for the period specified in this parameter, the fre-
quency converter trips. Disable the trip delay by setting the parameter to 60 s = OFF. Thermal monitoring
of the frequency converter will still remain active.
Function:
When the frequency converter detects an over-voltage in the set time trip will be effected after the set
time.
If value = 0, protection mode is disabled
NB!
It is recommended to disable protection mode in hoisting applications.
Function:
For internal service only.
Function:
Enter the proportional gain value for the current limit controller. Selection of a high value makes the
controller react faster. Too high a setting leads to controller instability.
Function:
Controls the current limit control integration time. Setting it to a lower value makes it react faster. A setting
too low leads to control instability.
