Accurax G5 servo drive
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 Enables vibration filter according parameter setting.
Gain switching Enables gain value according parameter setting.
Electronic gear switching 1 Switches the numerator fro electronic gear ratio.
Internal speed selection 3 Input to select the desired speed setting during internally speed operation.
The speed selecton is combining this input with VSEL1 and VSEL2 inputs.
Error counter reset input. Resets the position error counter.
Internal speed selection 2 Input to select the desired speed setting during internally speed operation.
The speed selecton is combining this input with VSEL1 and VSEL3 inputs.
Alarm reset input. Release the alarm status. The error counter is reset when the alarm is reset.
Control mode switching
Pulse prohibition input. Digital input to inhibit the position reference pulse.
Internal speed selection 1 Input to select the desired speed setting during internally speed operation.
The speed selecton is combining this input with VSEL2 and VSEL3 inputs.
Reverse run prohibited Overtravel prohibited: stops servomotor when movable part travels beyond the
allowable range of motion.
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 The function of input signals allocated to pins 8,9 and 26 to 33 can be changed with
these options by parameters settings
