Rated output: 0.4KW.
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 A61RP
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 A61RP.
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. MR-J2M multi axis servo amplifier substrate A61RP.
Groove position: 6.
The role of the implementation of the link is to control the signal requirements, the input of the various forms of energy into mechanical energy,
Drive the controlled object to work. The executive component in the mechanical and electrical integration system generally refers to all kinds of motor or hydraulic,
Pneumatic servo mechanism, etc..
Mechanical parameters include displacement, velocity, acceleration, force, and torque for the controlled object. "Universal output function: source type.

End cap.
High precision PWM control of the highest 200kHz.
In the PWM output mode, by setting the ON time and cycle time,
The duty cycle can be changed, and the minimum cycle time is 5 s.
In addition to lighting dimming control, simple motor control and heater control,
Can also be used to require high resolution detection equipment, such as a wide range of oscillators.
CPU built-in functions can be easily set through programming tools.
The built-in I/O function settings can be easilly carried out through the paraameters of the programming tool A61RP.
5 s units can be used for high precision workpiece measurement in pulse measurement mode,
Can be used with a minimum of 5 s units of the input signal of the ON/OFF time (the shortest 200 s) for high precision measurremment A61RP.
For example, after measuring the ON time of the sensor input,
The "moving speed" and "length" of the workpiece can be accurately calculated ". "
