Bridge Switch Delay Setting
Parm
744
Parameter Name
Bridge Switch Delay – Normal Applications (for armature time constants
in range of 1 to 100 mS) value should be set to 0.
Non–Zero Values will effect the bandwidth of the
drive.
Description
– High Inductance applications (Armature time
constants greater than 100mS) value needs to be
adjusted according to the parameter description
found in Chapter 7.
