(7) Positioning data initialization (
)
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] at 0 [V].
Automatic offset adjust is only valid for RYS-R basic type. SX bus and T-link types do not have the analog voltage input terminal.
Motor can be rotated with the analog speed command voltage, when FWD (or REV) signal command turns off all of X1, X2 and X3 of
multispeed selections.
When the speed command voltage is placed as neary 0 [V], motor may be rotates slowly.
Adjusting procedure of offset voltage is as follows :
(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 the ENT key, then the offset can be adjusted automatically.
(3) Make sure that the motor will not rotate even if the run command is on.
Remarks:
The adjustment result will be stored in system para. 64.
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 the servo lock is selected, the motor can be
stopped by the 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.
