External Wiring Diagram
Serial type 150, 300 A
(1) [
] The part indicated by the figure on the left should be wired with shielded
twisted pair (STP) cables.
(2) With a 150 A amplifier
The amplifier does not have DB1, DB2, TH1-1, or TH1-2 terminal block. The amplifier
has a built-in dynamic braking (DB) circuit, so there is no need for connecting an
external DB resistor.
With a 300 A amplifier
The amplifier does not have a built-in dynamic braking 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)
(3) Control panels must be grounded to prevent high voltages from damaging the
operation panel or machines in case of an electrical leakage. (Grounding of class C
or higher is recommended in Japan)
(4) Motor side connections vary depending on motor specifications. The red, white,
black, green, and orange indicated in the figure are for use when the motor has
lead-wire type power and brake lines. In the case of a cannon plug type, perform
wiring according to motor specifications.
(5) Refer to the encoder connection diagram for the wiring of encoder connectors.
(6) R, S, T, P, RB1, RB2, RB4, U, V, and W 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) Do not connect anything to the CN4-1, CN4-2, CN2-20, or CN2-21 pins.
(8) Use of a UL or IEC/EN compliant leakage circuit breaker is recommended.
(9) Can only be used when the brake is a 24 V brake. Power is supplied by a 24 VDC
power supply.
(10) 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.
(11) If the holding brake has a 24 V rated voltage, the brake can be directly powered by
the amplifier’s built-in holding brake power output, CNE.
(12) Consult us when conducting a withstand voltage test.
(13) An external power supply is to be prepared by the customer.
(14) Use of a UL or IEC/EN compliant leakage circuit breaker is recommended.
(15) For a 24 VDC power supply, use a SELV (safety extra low voltage) power supply with
reinforced insulation on I/O terminals.
(16) No wiring is required when using the battery-less absolute encoder.
