Digital input
[X1] Digital input 1 (1) Various signals (coast to a stop command, external alarm, multi-speed selection, etc) set
up by function codes E01 to E05, E98, E99 can be set up.
For details, refer to Chapter 5 “FUNCTION CODES”.
(2) Input mode, sink/source can be switched using SW1.
(Refer to “2.2.8 Operating slide switches”)
(3) The operating mode of the various digital input terminals when connected with terminal
CM (sink mode) / PLC (source mode) can be switched to “ON when shorted with CM/PLC
(active ON)” or “OFF when shorted with CM/PLC (active OFF)”
(4) Digital input terminal [X5] can be set up as a pulse train input terminal by changing the
function code
Maximum wiring length 20 meters
Maximum input pulse
30 kHz: When connected to open collector output pulse generator
100 kHz: When connected to complementary output pulse generator
For function code settings, refer to Chapter 5 “FUNCTION CODES”

Enable input (1) When terminals [EN1]-[PLC] or terminals [EN2]-[PLC] are OFF, the inverter output
transistors stop switching (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 terminals [EN1]-[PLC] and [EN2] – [PLC] using shorting bars when the enable input
function is not used (Keep the shorting 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 outputs. For details, refer to the page on “Transistor outputs”.
