CHAPTER 5 - PROGRAMMING INFORMATION AND SUGGESTIONS
43
English
If the optional keypad or serial communication is unavailable to
program the service factor parameter, it is necessary to use the
nominal current of the motor as the In of the motor x S.F. In this
case, the Motor Current trimpot must be programmed considering
the service factor.
Motor _ Current =
In _ of _ Motor x S.F.
x 100
In _ of _ SSW
Example:
Motor with 80 A and S.F.=1.25
SSW-07 of 130 A
80 x 1.25
x100=77%
130
TheMotorCurrenttrimpotmustthenbesetto77%.
NOTE!
The example and equation above must only be used when the
service factor is used, and if the parameter of the service factor is
not programmable via the optional keypad or serial communication.
