Function
AC power input terminals for the main circuit
AC power input terminals for the control circuit
Function
From 750 W to 1.5kW:
Terminals for outputs to the servomotor.
Ground terminal. Ground to 100Ω or less.
Function
Control power supply input for sequence signals: users must provide the +24 V power supply.
Allowable voltage range: 12 to 24 VDC
Emergency Stop Input
External Latch Signals
External general-purpose Input 0 This input is used as external general-purpose input.
External general-purpose Input 1
External general-purpose Input 2
Forward Torque Limit Input
Reverse Torque Limit Input
Forward Run Prohibit Input
Reverse Run Prohibit Input
Origin Proximity Input
Battery backup input for absolute
encoder
Function
The output turns OFF when an alarm is generated in the Servo drive.
General-purpose output.
The fucntion for this output is selected by changing the parameter:
INP1 (Positioning completed), VCMP (Speed conformity signal), TGON (Servomotor rotation speed detection), READY
(Servo ready), CLIM (Current limit detection), VLIM (Speed limit detection), BKIR (Brake interlock), WARN (Warning
signal)

If regenerative energy is high, connect an External
Regeneration Resistor between B1 and B2.
Normally B2 and B3 are connected. If regenerative energy
is high, remove the short-circuit bar between B2 and
B3 and connect an External Regeneration Resistor between
B1 and B2.
Input for emergency stop. Emergency stop function factory default: enable.
This external signal input latches the current value feedback pulse counter.
Minimal signal width must be 1 ms.
This signal input selects the torque limit.
Forward/ reverse drive rotation overtravel input. Stops servomotor when movable
part travels beyond the allowable range of motion.
Connect the origin proximity input signal in the origin search operation.
Connecting pin for the absolute backup battery. Do not connect when a battery is
connected to the servomotor encoder cable.
