SMCW6080

SMCW6080 Obtaining a particular starting time value is only a consequence of the motor torque reduction and can not be guaranteed or easily repeatable. The rotary switch « Time (s) » setting values only give the duration of the voltage ramp applied to the motor but not necessarily its starting time. The main SMCV function is to obtain a motor torque reduction to take care of the motor load and the electric grid. The motor starting time is only a consequence and completely depends on the motor itself, its load and the settings done by the user.

The SMCV SMCW6080 can not break a motor driving a load that has much inertia. The user can only obtain a stop time equal or longer than a simple disconnection from the electric grid. Using the softstop feature can only be justified when the motor load tends to break the motor (pumps, .) or when the products treated by the machine need to be stop slowly (conveyors,.). In the case of load with high inertia, the softstop feature can help to reduce slowly the magnetic field inside the motor to avoid long time overvoltage in the circuit.
