Test Operation Mode
6
Follow the procedure below to adjust the offset voltage.
[1] Supply 0 V to the [VREF] and [TREF] terminals. The operation command can be given or not
given.
[2] Select [ Fn09 ] at the keypad and press the [SET/SHIFT] key to automatically adjust the offset.
[3] Turn the operation command [S-ON] signal on and check that the output shaft of the
servomotor does not rotate.

Results of adjustment are stored in parameter PA3_32 and PA3_34.

According to variation in the ambient environment of the servo amplifier, offset
adjustment may become necessary. However, do not select if the host controller uses
the speed command voltage and division output pulse (feedback) to control the servo
amplifier.
(10) Z-phase offset adjustment
The current position is defined to be the Z-phase position.
After the Z-phase offset is defined, the distance between
the current position and Z-phase is automatically entered in
parameter PA1_12 (Z-phase offset).

The zero position (Z-phase) of the encoder
is not established (immediately after the
power is turned on). In this case, turn the
motor shaft two or more turns to establish
the Z-phase.
(2) Refer to "NG display (common)" on page 6-43.
