200 to 240V ±10%; 50 to 60Hz ±5%
Feature
Improves accuracy
Since rotation is perfectly synchronized with the command frequency, speed control is precise and immune to disturbances or load fluctuations. Flexible and intuitive controls allow for exact operations over a wide range of speeds.
Dramatically reduces equipment costs
No gear is needed, thanks to the system¡Çs low-speed, high torque capabilities. Best of all, a single driver can control multiple motors. Moreover, superlative torque distribution decreases the time needed for mechanism adjustments and maintenance.
No mechanical brake required
Some of the outstanding features of the G series system include a position-retention function, instantaneous response motions such as start-up, stop, and reverse, and a simple positioning system that can be configured by an I/O command from the controller.
