4.7 MOTOR CURRENT SETTING

This setting defines the ratio of the SSW-08 current and the motor current. The value of the 

setting is very important since it defines the protection of the motor driven by the SSW-08. The 

setting of this function interferes directly in the following motor protections:

Overload;

Overcurrent;

Stall;

Phase loss.

Calculation Example:

SSW-08 Used: 30 A

Motor Used: 25 A

Trimpot for the Motor Current Setting

Motor Current Setting =  I

Motor Current Setting = 0.833

Therefore it must be set at 83 %
