Drive: MR-H_ACN series built-in positioning function.
Rated output: 15KW.
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 HC-RFS103B
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 MITSUBISHI .
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 MITSUBISHI . "Universal output function: source type .
Program capacity: 260K step.
Basic operations processing speed: 9.5ns.
Communication interface: USB/Ethernet.
Program capacity: 20K step.
Control mode: stored procedure repeated operation.
Input / output points: 4096 points.
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 easily carried out through the paraameters of the programmingg tool MITSUBISHI HC-RFS103B.
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 MITSUBISHI HC-RFS103B.
For example, after measuring the ON time of the sensor input,
The "moving speed" and "length" of the workpiece can be accurately calculated ". "
