3.1.2. Connector and terminal of the drive
Three-phase main
circuit for RST power
input
Connect the three-phase AC power supply. (Select adequate input voltage
based on the product number.)
Connect the single-phase AC power supply. (Select adequate input voltage
based on the product number.)
Connect the cable to the motor. U (red) V (white) W (black) and FG (green)
connect to the grounding area of the drive.
Regenerative resistor
(braking resistor)
contact
Use the internal resistor.
Make sure that it is short circuited between P and
D and it is open circuited between P and C.
Use the external resistor.
Connect the regenerative resistor to P and C. Make
sure that it is open circuited between P and D.
Use the external braking
unit.
Connect P+ and P- of the braking unit to the P and
N ends of the servo motor. Open the circuit for the
P and D ends, as well as the P and C ends.
Electrical connection
terminal
The contact for the earth wire of the power supply and motor
It connects to the upper controller.
It connects to the motor encoder.
It connects to the computer.
*Analog voltage output
terminal*
The monitoring (output) of the analog data, including MON1, MON2, GND
The following must be noted for wire connecting:
1. When the power is cut off, do not touch the six major power lines R, S, T and U, V, W. It is allowed
to touch the lines after the charging light goes off.
2. Keep the six major power linesR, S, T and U, V, W away from other signal cables. Try to keep the
distance above 30 cm.
3. For extending the connecting line for encoder CN2, use the twisted-pair signal cable with isolated
grounding. Keep the cable within 20 m. If its length exceeds 20 m, use the one with the wire diameter
twice larger than the current one to keep the signal level from excessive attenuation.
