Main Setup [200]
Section 11-2
When the selection Trip is set in menu [231] the VSD trips if this limit is
exceeded.
When the selection Limit is set in menu [231] the VSD reduces the torque if
the integrated value is 95% or closer to the limit, so that the limit cannot be
exceeded.
Note
If it is not possible to reduce the current, the VSD will trip after exceeding
110% of the limit.
Example
In Fig. 65 the thick grey line shows the following example.
•
Menu [232] Mot I
2
t Curr is set to 100%.
1.2 x 100% = 120%
•
Menu [233] Mot I
2
t Time is set to 1000 s.
This means that the VSD will trip or reduce after 1000 s if the current is
1.2 times of 100% nominal motor current.
Only visible if the PTC/PT100 option board is installed. Set the PTC input for
thermal protection of the motor. The motor thermistors (PTC) must comply
with DIN 44081/44082. Please refer to the manual for the PTC/PT100 option
board.
Menu [234] PTC contains functions to enable or disable the PTC input. Here
you can select and activate PTC and/or PT100.
