Pick-up Operation begins at a preset pick-up frequency to search for the motor speed to start an idling motor without stopping it.
Automatic deceleration When the torque calculation value exceeds the limit level set for the inverter during deceleration, the output
frequency is automatically controlled and the deceleration time automatically extends to avoid an trip.
The motor loss increases during deceleration to reduce the load energy regenerating at the inverter
to avoid an trip upon mode selection.
The output voltage is controlled to minimize the total sum of the motor loss and inverter loss at a constant speed.
Overload Prevention Control The output frequency is automatically reduced to suppress the overload protection trip o inverter
caused by an increase in the ambient temperature, operation frequency, motor load or the like.
Auto-tuning The motor parameters are automatically tuned.
Cooling fan ON/OFF control Detects inverter internal temperature and stops cooling fan when the temperature is low.
Secondary motor setting One inverter can be used to control two motors by switching (switching is not available while a motor is running). Base
frequency, rated current, torque boost, electronic thermal, slip compensation can be set as data for the secondary motor.
The second motor constants can be set in the inverter. (Auto-tuning possible)
Universal DI The presence of digital signal in a device externally connected to the set terminal can be sent to the master controller.
Universal AO The output from the master controller can be output from the terminal FM.
Speed control The motor speed can be detected with the pulse encoder and speed can be controlled.
Positioning control Only one program can be executed by setting the number of pulses to the stop position and deceleration point.
Rotation direction control Select either of reverse prevention or forward rotation prevention.
