14-25 Trip Delay at Torque Limit
Range: Function:
60 s* [0 - 60 s] Enter the torque limit trip delay in seconds. When the output torque rea-
ches the torque limits (par.4-16
Torque Limit Motor Mode and par.
4-17
Torque Limit Generator Mode), a warning is triggered. When the
torque limit warning has been continuously present for the period speci-
fied in this parameter, the adjustable frequency drive trips. Disable the
trip delay by setting the parameter to 60 s = OFF. Thermal adjustable
frequency drive monitoring will still remain active.
14-26 Trip Delay at Inverter Fault
Range: Function:
Applica-
tion de-
pend-
ent*
[0 - 35 s] When the adjustable frequency drive detects an overvoltage in the set
time, tripping will be affected after the set time.
14-28 Production Settings
Option: Function:
[0] * No action
[1] Service reset
[2] Set Production Mode
14-29 Service Code
Range: Function:
0 N/A* [-2147483647 -
2147483647 N/A]
Service use only.
14-3* Current Limit Control
The adjustable frequency drive features an integral current limit controller which is activated when the motor
current, and thus the torque, is higher than the torque limits set in par.4-16
Torque Limit Motor Mode and par.
4-17
Torque Limit Generator Mode.
When the current limit is reached during motor operation or regenerative operation, the adjustable frequency
drive will try to reduce torque below the preset torque limits as quickly as possible without losing control of the
motor.
While the current control is active, the adjustable frequency drive can only be stopped by setting a digital input
to
Coast inverse
[2] or
Coast and reset inv.
[3]. Any signal on terminals 18 to 33 will not be active until the adjustable
frequency drive is no longer near the current limit.
By using a digital input set to
Coast inverse
[2] or
Coast and reset inv.
[3], the motor does not use the ramp-down
time, since the adjustable frequency drive is coasted.
14-30 Current Lim Cont, Proportional Gain
Range: Function:
100 %* [0 - 500 %] Enter the proportional gain value for the current limit controller. Selec-
tion of a high value makes the controller react faster. Too high a setting
leads to controller instability.
