13. SERVO AMPLIFIERS WITH A LARGE CAPACITY
(
30k TO 55kW
)
Note 1. For power supply specifications, refer to section 13.1.3.
2. Configure the circuit to turn OFF the forced stop (EM1) of the drive unit and the converter unit at the same time.
3. Always connect P
1 and P2 terminals (Factory-wired). When using the power factor improving DC reactor, refer to section 13.9.6.
4. Connect P/
and N/ terminals of the brake unit to a correct destination. Wrong 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: 1a contact, 110VAC_5A/220VAC_3A
Normal condition: TH1-TH2 is conducting. Abnormal condition: TH1-TH2 is not conducting.
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. Always connect BUE and SD terminals (Factory-wired).
11. Connect MSG and SD terminals of the brake unit to a correct destination. Wrong 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) of
this section.
(c) Precautions for wiring
The cables between the converter unit and the brake unit, and between the resistor unit and the brake
unit should be as short as possible. Always twist the cable longer than 5m (twist five times or more per
one meter). Even when the cable is twisted, the cable should be less than 10m. Using cables longer
than 5m without twisting or twisted cables longer than 10m, may result in the brake unit malfunction.
