High performance compact inverters

Frenic-Multi Series inverters from Fuji Electric are wellsuited

for vertical and horizontal conveyance. Impacts are detected mechanically and not only can the inverter’s operation

pattern be set on coast-to-stop or deceleration stop, but switching from torque limitation to current limitation and

generating a holding torque (hit-and-stop control) can be selected, making it easy to adjust brake application and release

timing. At brake release time, after the motor operates, torque generation is detected and signals are output. At brake application time, brake application that matches the timing can be done, and so mechanical brake wear is reduced. Inverters are equipped with two limit operations, “torque limitation” and “current limitation,” so either can be selected to match the

equipment used with the inverter.
