(1) [
] The part indicated by the figure on the left should be wired with shielded
twisted pair (STP) cables.
(2) An external regenerative resistor should be connected between the RB1 and RB2 terminals.
(3) Consult us when selecting an external dynamic brake resistor.
(4) Motor side connections vary depending on motor specifications. Perform connections
according to the specifications.
(5) Refer to the encoder connection diagram for the wiring of encoder connectors.
(6) R, S, T, +DC, -DC, RB1, RB2, U1, V1, W1, U2, V2, and W2 are high-voltage circuits. All
other signal lines are low-voltage circuits. When wiring, provide sufficient clearance
between high-voltage and low-voltage circuits.
(7) Ground with a wire of 5.5 mm
2
or larger size.
(8) The amplifier does not have a built-in dynamic brake circuit. DB1 and DB2 are DB
timing outputs, and TH1-1 and TH1-2 are DB resistor thermostat inputs. When not
using a thermostat, ensure that TH1-1 and TH1-2 are short-circuited. Necessary items,
an electromagnetic contactor, resistor, power supply, and cable, are to be prepared by
the customer. For the electromagnetic contactor, prepare one that works with DC
power. Relay contact rating: 30 VDC, 2 A (cosø = 0.4, L/R = 7 ms)
(9) Use a shielded twisted pair (STP) cable of Category 5e or higher (TIA).
(10) Do not connect anything to the CN4-1, CN4-2, CN2-20, or CN2-21 pins.
(11) An external power supply is to be prepared by the customer.
(12) Consult us when conducting a withstand voltage test.
(13) For the wiring of unit-to-unit cables, refer to the wiring diagram in the Instruction
Manual (M0011694).
(14) CN4 is a connector for the Safe Torque Off function. Turning Servo ON (motor in
operation) requires to connect a safety device to CN4 and get STO enabled. When
not using STO, be sure to insert the short-circuiting STO connector (Mfr. part no.:
1971153-2) to CN4.
(15) The CN2-20 to CN2-25 pins are used for tandem operation.
Connect compatible amplifiers as on the right.

(16) When using an incremental encoder to configure a semi-closed system, connect
it to EN2.
(17) Use of a UL or IEC/EN compliant leakage circuit breaker is recommended.
(18) For a 24 VDC power supply, use a SELV (safety extra low voltage) power supply
with reinforced insulation on I/O terminals.
(19) No wiring is required when using the battery-less absolute encoder.
