Figure 2.2-8 Control circuit terminals layout
The following terminals will have high voltage when the power is ON.
Control terminals: AUX-contact (30A, 30B, 30C, Y5A, Y5C)
Insulation level
Contact output – control circuit : Enhanced insulation (overvoltage category II, degree of contamination 2)
Risk of electric shock exists

Enable input
(1) When terminals [EN1]-[PLC] or terminals [EN2]-[PLC] are OFF, the inverter output
transistors stop functioning. (Safe Torque Off: STO)
Be sure to operate terminals [EN1] and [EN2] simultaneously; otherwise an ecf alarm is
issued and the operation of the inverter will be disabled.
To enable the Enable function, remove the short bar.
(2) The input mode for terminals [EN1] and [EN2] is fixed to source. The mode cannot be
switched to sink.
(3) Short-circuit terminals [EN1]-[PLC] and [EN2]-[PLC] with short bars when the Enable
input function is not used. (Keep the short bar connected).

(1) The terminal is used for connecting the output signal power source of the programmable
controller (rated voltage DC +24 V (power supply voltage fluctuation range: DC +22 to
+27 V) maximum 100 mA).
(2) The terminal can also be used for the power source for the load connected to the
transistor output. For details, refer to the page on transistor output.
