Function
Reference pulse input for line driver and open collector according to parameter setting.
Input mode:
Sign + pulse string
Reverse/forward pulse (CCW/CW pulse)
Two-phase pulse (90° phase differential)
Reference pulse input for line driver only.
Input mode:
Reverse/forward pulse (CCW/CW pulse)
Speed reference input: ±10 V/rated motor speed (input gain can be modified using a parameter).
Torque reference input: ±10 V/rated motor torque (input gain can be modified using a parameter).
Speed limit input: ±10 V/rated motor speed (input gain can be modified using a parameter).
Analog signal ground
Torque reference input: ±10 V/rated motor torque (input gain can be modified using a parameter).
Forward torque limit input: ±10 V/rated motor torque (input gain can be modified using a parameter).
Reverse torque limit input: ±10 V/rated motor torque (input gain can be modified using a parameter).
Analog signal ground
Control power supply input for sequence signals: users must provide the +24 V power supply (12 to 24 V).
Servo ON: this turn ON the servo.
Vibration filter switching 1
Gain switching

Internal speed selection 3
Error counter reset input.
Internal speed selection 2
Alarm reset input.
Control mode switching
Pulse prohibition input. Digital input to inhibit the position reference pulse.
Internal speed selection 1
Reverse run prohibited
Forward run prohibited
Sensor ON input. Initial data request signal when using an absolute encoder.
Sensor ON signal ground.
Backup battery connection terminals when the absolute encoder power is interrupted. Do not connect when a absolute
encoder battery cable for backup is used.
Frame ground
Torque limit switch
Vibration filter switching 2
Electronic gear switching 2
Zero speed
Speed command signal
Torque command signal
Emergency stop
Inertia ratio switching
Enables vibration filter according parameter setting.
Enables gain value according parameter setting.
Switches the numerator fro electronic gear ratio.
Input to select the desired speed setting during internally speed operation.
The speed selecton is combining this input with VSEL1 and VSEL2 inputs.
Resets the position error counter.
Input to select the desired speed setting during internally speed operation.
The speed selecton is combining this input with VSEL1 and VSEL3 inputs.
Release the alarm status. The error counter is reset when the alarm is reset.
Position ↔ speed
Position ↔ torque
Torque ↔ speed
Input to select the desired speed setting during internally speed operation.
The speed selecton is combining this input with VSEL2 and VSEL3 inputs.
Overtravel prohibited: stops servomotor when movable part travels beyond the
allowable range of motion.
The function of input signals allocated to pins 8,9 and 26 to 33 can be changed with
these options by parameters settings
Enables control mode switching
