7.2

Current limiting function

Operating principle

Activate the current limiting function if you want to ensure that a specific current value is not

exceeded during motor starting.
The motor is always started up with the voltage ramp. Before the current exceeds the

parameterized current limit value x I

, the voltage ramp function is aborted and the current

limitation function starts. If the motor current drops below the limit value again, the voltage

ramp function takes over control again until the motor has finished starting up.

①

direct starting motor

②

soft starter

: Adjustable current limiting value

③

Voltage ramp
