Initializes all positioning data.
* After initializing, be sure to turn off and on power.
(8) Automatic offset adjust ( )
Sets the input voltage to the control input terminals [NREF] and [TREF] at 0 [V].
When the motor rotates slowly with the run command given, the speed
command voltage offset is generated. (Where the speed command
voltage is selected in speed control)
(1) Sets 0 [V] at the terminal [NREF].
Whether the run command is given or not has no influence.
(2) Select [ ] on the keypad panel and press ENT key, then the
offset can adjusted automatically.
(3) Make sure that the motor will not rotate even if the run command is ON.
Remarks:
Both the terminal [TREF] and [NREF] can be adjusted simultaneously by the automatic offset adjust.
The adjustment result will be stored in system paras. 64 and 66.
Along with the change of ambient environment, the offset adjust may be required again.
With the setting of system para. 81, the operation at stoppage can be selected. When “servo lock” is selected, the motor can be stopped
by “servo lock” even in speed control mode. However, when the host controller is controlling the amplifier using the speed command
voltage and freq. dividing output pulse (feedback), do not select the “servo lock.
