Drive: MR-H_ACN series built-in positioning function.
Rated output: 0.6KW.
In servo drive speed closed loop,
Rotor speed measurement accuracy is very important to improve the dynamic and static characteristics of the speed control loop.
In order to seek the balance between measurement precision and system cost, incremental photoelectric encoder is generally used as the speed measuring sensor,
The corresponding method is M/T velocity measurement MR-J2S-70B
Although the M/T measurement method has a certain measurement accuracy and a wide range of measurement,
But this method has its inherent defects,
Mainly includes: the measurement period must be detected at least one complete encoder pulse, limiting the minimum detectable speed.
2 control system for speed control of the timer switch is difficult to maintain synchronization,
Can not guarantee the accuracy of measurement in the situation where the speed change is larger.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method. Superior high efficiency IPM motor.

Energy saving by high efficiency motor.
Reduce standby power consumption.
DC24V external power supply, the input MC signal can be stopped after the motor for the OFF, in the motor drive for the ON.
Standby power management can be carried out by means of frequency converter to realize the power consumption reduction of standby time.
According to the temperature of the inverter cooling fan, the operation of the inverter can be controlled.
According to the operating conditions of the inverter cooling fan output the corresponding signal,
Therefore, the inverter and other built-in fan and inverter cooling fan synchronous operation.
Can reduce the power consumption in the stop.
