11. OPTIONS AND AUXILIARY EQUIPMENT
Note 1. When not using the phase detection terminals, fit the jumpers across RX-R, SX-S and TX-T. If the jumpers remain removed,
the FR-RC will not operate.
2. For the servo amplifier of 7 kW, always disconnect the lead wire of built-in regenerative resistor, which is connected to the P+
3. and C terminals.
If disabling ALM (Malfunction) output with the parameter, configure up the power supply circuit which switches off the magnetic
4. contactor after detection of alarm occurrence on the controller side.
Always connect between P3 and P4 terminals. (factory-wired) Use either the power factor improving DC reactor or the power
5. factor improving AC reactor. When using the power factor improving DC reactor, refer to section 11.11.
6. For power supply specifications, refer to section 1.3.
Set [Pr. PA04] to "0 0 _ _" to enable EM1 (Forced stop 1). Configure up the circuit which shuts off main circuitpower with
7. external circuit at EM1 (Forced stop 1) off.
When wires used for L11 and L21 are thinner than wires used for L1, L2, and L3, use a molded case circuit breaker.
8. This diagram is for sink I/O interface. For source I/O interface, refer to section 3.9.3.
