13. OPTIONS AND AUXILIARY EQUIPMENT
Note 1. For power supply specifications, refer to section 1.3.
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 to 22kW, do not connect a supplied regenerative resistor to the P and C
terminals.
3. For the servo amplifier of 11k to 22kW, always connect P
1
and P (Factory-wired). When using the power factor improving DC
reactor, refer to section 13.2.4.
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 amplifier of 11kW or more, connect the thermal relay censor of the servo amplifier.
8. For the servo amplifier of 3.5kW, always disconnect the wiring between P and D terminals.
9. Do not connect more than one cable to each P and N terminals of the servo amplifier.
10. Make sure to connect BUE and SD (Factory-wired).
