Grizzly Variable Frequency Servo Control VFSC System
|
The Grizzly Closed Loop Servo Control System has high sensitivity which can detect minute changes occurring in the operation and provide adequate feedback control, for example: with a strong wind, the air pressure will slow down the door’s moving speed; at this moment, the closed loop servo control system will transmit a signal to slightly increase the motor power in order to maintain the prefixed operating speed. Repeated operation of the door could cause temperature rise and damper decrease in the motor, which could potentially cause the system to control of the closing speed of the door. The Closed Loop Servo Control System can monitor the speed of the motor to ensure the stable operation of the doors, avoiding any possible defective situation and door collision. |
