Danfoss VLT Programming Guide

[2] Initialisation Select Initialization [2] to reset all parameter values to default settings, except for par. 15-03 Power
Up's
, par. 15-04 Over Temp's and par. 15-05 Over Volt's . The frequency converter will reset during
the next power-up.
Par. 14-22
Operation Mode will also revert to the default setting Normal operation [0].
[3] Boot mode
14-23 Typecode Setting
Option: Function:
Typecode re-writing. Use this parameter to set the typecode matching the specific FC.
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 reaches 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 specified in
this parameter, the frequency converter trips. Disable the trip delay by setting the parameter to 60
s = OFF. Thermal frequency converter monitoring will still remain active.
14-26 Trip Delay at Inverter Fault
Range: Function:
Application
dependent*
[0 - 35 s] When the frequency converter detects an over-voltage in the set time trip will be effected 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.
3.14.5 14-3* Current Limit Control
The frequency converter 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 frequency converter will try to reduce torque below the preset
torque limits as quickly as possible without losing control of the motor.
