15. SERVO AMPLIFIERS WITH A LARGE CAPACITY
(
30k TO 55kW
)
Note 1. For power supply specifications, refer to section 15.1.3.
2. Make up a sequence that will concurrently turn off the Emergency stop (EMG) of the drive unit and the Forced stop (EM1) of the
converter unit, and shut off the main circuit power supply by the external sequence.
3. Make sure to connect between P
1 and P2 terminals (Factory-wired). When using the power factor improving DC reactor, refer to
section 15.9.6.
4. Connect P/
and N/ terminals of the brake unit to a correct destination. Incorrect connection results in the converter unit and
brake unit malfunction.
5. For the converter unit and the drive unit of 400V class, a stepdown transformer is required.
6. Contact rating: 1b contact, 110VAC_5A/220VAC_3A

7. 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.
8. Connect the thermal relay censor of the servo motor.
9. Do not connect more than one cable to each L
and L terminals of TE2-1 of the converter unit.
10. Make sure to connect between BUE and SD terminals (Factory-wired).
11. Connect MSG and SD terminals of the brake unit to a correct destination. Incorrect connection results in the converter unit and
brake unit malfunction.
12. For connecting L
and L - terminals of TE2-1 of the converter unit to the terminal block, use the cable indicated in (3) (d) in
this section.
