1 Overview
MCAC706 is designed and manufactured using DSP vector control,
closed loop servo drives with low-cost and all-digital AC.It includes three
adjustable feedback loop control which are position loop, speed loop and
current loop. It has stable performance which suitable for driving voltages
between 48V and 80V, and the power below 400W AC servo motor.
2 Characteristics
2.1 More than one kinds of pulse input mode
Pulse + direction
CW /CCW double pulse
A / B phase pulse
2.2 Servo reset input interface optocoupler isolation ERC
2.3 Current loop bandwidth: (-3dB) 2KHz (the typical value)
2.4 Speed loop bandwidth: 500Hz (the typical value)
2.5 Position loop bandwidth: 200Hz (the typical value)
2.6 Motor encoder inputs upright post :differential input (26LS32)
2.7 RS232C interface parameters available to download via PC
or text display
2.8 Overcurrent, I2T, overvoltage, undervoltage,Overtempera-
ture, speeding, over-differential protection
2.9 The green light indicates running and the red light indicates
that the protection or offline
