DETAILED PARAMETER DESCRIPTION
NOTE!
1) For this function, the parameter P54 must be programmed
at 4 and P28 = OFF.
2) Direction of rotation cannot be performed when Soft-
Starter is connected within the motor delta connection
(P28=ON).
3
- Function direction of rotation. The relay is ON when digital
input (DI3) is closed, and OFF when digital input is open (DI3).
The relay controls a contactor that must be connected at the
SSW-03 Plus output, which reverse the direction of rotation
by inverting two motor phases - See Item 9.7 - Typical Appli-
cation with Reversal.

It enables the Relay RL2 to operate according to the
parameters set bellow:
1-2 - Enables the Relay RL2 to operate according to the
parameters described in Item 6.4.6.
3 - Function DC braking. The relay is ON when the Soft-Starter
receives an OFF command. For this function an additional
contactor must be used. See Item 9.6 - Typical diagram for DC
braking.
