）
When you use the drive of type C and D with single phase input, connect to L1 and L3 of the main power input
terminal. Do not connect anything to L2 terminal.
2
）
Use the insulated crimp terminal for the connection to the terminal block.
3
）
Cover of the terminal block is fastened with screws. Take off these screws to open the cover for connection.
4
）
When you do not use an external regenerative resistor, short between RB2(B2)and RB3(B1)terminal.
It is required to install an external regenerative resistor when the drive trips due to regenerative resistor overload
(No.18).
Connect the external regenerative resistor between RB1 (P) and RB2 (B2) terminal after taking off the short bar
between RB2 (B2) and RB3 (B1).
Since type A and B drive is not equipped with built-in regenerative resistor, Shorting between RB2 and RB3 is not
required, however connect the external regenerative resistor when the drive trip due to the same error as the
above.
Set up 1 or 2 to Pr.6C(Selection of external regenerative resistor).
5
）
Apply the voltage to the drive as specified in the name plate.
6
）
Do not make reversed connection of power input terminals(L1
，
L2
，
L3) and motor output terminals(U
，
V
，
W).
7
）
Do not ground fault motor output terminals (U
，
V
，
W)or short them each other.
8
）
Never touch power connectors, X1 and X 2 since high voltage is applied to them. Risk of electric shocks.
9
）
When the max current of circuit breaker for 750W or larger model is protected by 20A, max. capacity to be
delivered
to the circuit will be 50Arms 240V. Do not make the load get larger than this.
10
）
You cannot change the rotational direction of the servo motor by switching the 3 phases like an induction motor.
Match up the output terminals (U, V, W) of the servo drive and color of the motor cables (pin No. in case of a
cannon plug).
11
）
Connect the earth terminal of the servo drive and that of the motor securely, and ground them together with the
earth terminal of the noise filter. Ground the machine itself. Grounding to be with grounding resistance of
100[ohm] or less. Use the insulated crimp terminals for connection.
12
）
Insert a surge absorbing circuit between contacts of electro-magnetic contactor and relays, or to coil or brake
winding of the motor with brake for noise prevention.
13
）
Install a non-fuse breaker to shut off the power externally in emergency case. Use a ground-fault breaker with a
harmonic measure.
14
）
Install a noise filter to reduce terminal noise voltage.
15
）
Power supply for the motor brake to be prepared by customer.
16
）
Make the power supply to apply voltage only after the wiring is finished.
