3.4.1.2 Typical wiring example of the main circuit

3.4.1.3 Situation of using multiple servo units

The alarm output of each servo unit "ALM" is all connected in series so that the alarm can detect the action from relay "1RY". The output transistor is OFF when the ALM output is in state of alarm. The circuit has a Circuit Breaker "QF" and a noise filter, and they can be used together. It is suggested to choose the proper Circuit Breaker and noise filter that suit for specifications for total power capacity of the multiple servo units (the load condition should be considered).

1. The space between peripheral devices such as controllers and the servo-driver should be no more than

2. It should have at least 30cm space between the control cables and the power cables, and between the control cables and motor cables; do not put them into the same pipeline or band them together.

3. External 24V DC power supply is used for IO, and the capacity should be lager than 250mA.

4. The load on the switch input and output terminals should be NOT lager than 25V or lager than 50mA.

5. It is necessary that parallel freewheeling diode at the both ends of the load, when switch output signal directly drive inductive loads such as relays.

Before switching on the power, make sure the following is checked:

1、Wiring

1）Servo-driver power (R, S, T) must be correctly connected;

2）Output phases of Servo-driver (U, V, W) must match the servo motor cables phases；

3）There is no shorting connection between output of Servo-driver (U, V, W)and the input power (R, S, T);

4）All wirings must meet the standards of wiring shown in chapter 5.1.1;

5）Make sure the enable terminal (SON) of external servo is set to state OFF；

6）Servo-drivers and servo motor must be well grounded;

7）Voltage applied to J2 port can not exceed DC24V;

8）Stress that applied to the cables should be within the specified range.

2、Environment

There are no wires, metal chips and the other things that could cause the signal lines and power lines shorted in the environment.

3、The mechanical part

Do not let the motor running under the condition of negative load. The so-called negative load is that the torque direction of the motor output is opposite to the running direction of the motor.

Checking all above are correct before the power is switched on.

Attention：

Do not have direct contact with electrical lines terminals, after the main circuit power supply is turned on, even when the servo is not turned on, because it may cause electric shock.
