Note 1. For power supply specifications, refer to section 1.2.
2. For the servo amplifier of 5k and 7kW, always disconnect the lead of built-in regenerative resistor, which is connected to the P
and C terminals. For the servo amplifier of 11k and 15kW, do not connect a supplied regenerative resistor to the P and C
terminals.
3. Always connect P
1
and P
2
terminals (P
1
and P for the servo amplifier of 11k and 15kW) (Factory-wired). When using the power
factor improving DC reactor, refer to section 14.11.
4. Connect the P/ and N/ terminals of the brake unit to a correct destination. Wrong connection results in servo amplifier and
brake unit malfunction.
5. Contact rating: 1b contact, 110VAC_5A/220VAC_3A
Normal condition: TH1-TH2 is conducting. Abnormal condition: TH1-TH2 is not conducting.
6. Contact rating: 230VAC_0.3A/30VDC_0.3A
Normal condition: B-C is conducting/A-C is not conducting. Abnormal condition: B-C is not conducting/A-C is conducting.
7. For the servo motor with thermal sensor, connect the thermal sensor of the servo motor.
8. Do not connect more than one cable to each P and N terminals of the servo amplifier.
9. Always connect BUE and SD terminals (Factory-wired).
10. Connect the MSG and SD terminals of the brake unit to a correct destination. Wrong connection results in servo amplifier and
brake unit malfunction.
11. For the cable to connect the terminal block and the P and N terminals of the servo amplifier, use the cable indicated in (4) (b) in
this section.
12. The diagram is for when outputting the malfunction (ALM) is enabled by changing the parameter. If disabling malfunction (ALM)
output, configure the power supply circuit which switches off the magnetic contactor after detection of alarm occurrence on the
controller side.
13. Configure the circuit which shuts off main circuit power with external sequence at forced stop (EMG) off.
