Product Description: 24V/10A DC Servo Motor Drive


24V/10A DC Servo Motor Drive

Summary

MMT all-digital DC servo drive system adopts high-performance digital signal processor (DSP) and integrated circuit, and come out to be a cost effective product with simple circuit, high integration, easy operation, and strong practicability. MCAC506 provides three feedback loops: position loop, velocity loop and current loop. Three work control mode: position, velocity and torque.  MMT matches with DC servo motor under 50V and 200W.

 

Features

* Position control: light isolate input PULSE/DIRECTION or CW/CCW signal;

* Speed control: input simulate 0-3.3V voltage signal (speed input by Pos.ff);

* Torque control: input simulate 0-3.3V voltage signal (torque input by Pos.ff);

* Light isolation servo reset input interface ERC;

* Light isolation servo failure alarm output interface ALM;

* Width of current loop: (-3dB) 2KHz (typical value);

* Width of velocity loop: 500 Hz (typical value);

* Width of position loop: 200 Hz (typical value);

* Quadrature encoder input interface at motor side: differential input (26LS32);

* Allow parameters download by pc or text display through interface RS232C;

* Perfect protection against overload, I2T, over-voltage, under-voltage, overheating, over  speed, overproof protection;

* Green light for on, red light for protected mode or offline.

Parameter adjusting and setting

(Potentiometer adjusting, CCW to minimize value, CW to maximize value)

One 4 bit double row pin on drive circuit board for the working mode setting, number 1, 2, 3, 4 respectively from the outer to inner side.

no plug in, position mode is pulse/direction;

plug in 1, speed control, speed input by Pos.ff;

plug in 2, torque control, torque input by Pos.ff;

plug in 1 and 2, position control for positive pulse/negative pulse input;

plug in 3, position control pulse/direction, but converse running direction.

 

B) 11 scale on the potentiometer, CCW to minimize the value to 0, CW to maximize the value to 10, and 5 in the middle.

Pos.ff : Position Feed-forward Control

Pos.P: position proportional gain control

Pos.D: position differential control

Vel.p : velocity proportional gain control

Tor. P: Current proportional gain control

 

Servo system includes three feedback loop: position, velocity and torque(current). The inner loop responses with the fastest speed, and the middle loop must response faster than the outer loop. A vibration or poor response will happen when the rule has not been followed. Customer needs to adjust the parameter of position loop and velocity loop only. Parameters of system would restrict each other, the output of position feedback would be unstable when just only the position feedback gains, which would lead to an unstable result of the whole servo
