Note:
(1) The input of the analog voltage command for torque limitation has no polarity. The torque
limit value based on the absolute value is applicable to the two directions of forward rotation and
reverse rotation.
(2) The maximum allowable voltage of the analog input signal is ± 10V. Do not apply more than ±
10V to the motor.
5.5.3.3 Analog voltage torque filter
Analog voltage torque
command filter
Make the torque command input pass through the delay filter to smooth the torque command. Setting
too large will reduce responsiveness.
5.5.3.4 Torque command offset auto-tune (F1-04)
When analog voltage torque mode is used, the immediate command voltage is 0V, and the motor
rotates at a small speed. This fretting occurs when the command voltage of the upper control unit or the
external circuit deviates by a small amount (mv). In this case, the panel operator can be used to adjust
the instruction offset automatically.
When the servo enable is turned off, i.e. bb state, unplug the analog signal of CN1 port of the driver,
and carry out the following operations:
Press STATUS/ESC to exit.
Note:
(1) The current voltage of analog quantity is 0V, calibrated according to F1-04 process above, 0V is 0%
output torque, lower than 0V motor reverse output torque, higher than 0V motor forward output torque;
similarly, if the current voltage of analog quantity is 5V, calibrated according to F1-04 process above,
5V is 0% output torque, lower than 5V motor reverse output torque, higher than 5V motor forward
output torque.
(2) If there is still fretting after the offset is adjusted automatically, increase the parameter P3-26
appropriately. If it is changed to 5, it means the dead band voltage is 0.005v.
