5 SVA Module Specifications and Handling
5.4.1 Motion Fixed Parameters
5-52
5.4 SVA-01A and SVA-02A Parameters
This section details various parameters used for the SVA-01A and SVA-02A Modules.
5.4.1 Motion Fixed Parameters
Motion fixed parameters cannot be changed if the current value of bit 0 is ON in motion setting param-
eter OW††01, RUN Command Settings.
Positions and other data are initialized when a motion fixed parameter is changed.

No. Name Description Factory
Setting
1 Axis Selection
(USESEL) Set whether an axis is used or not.
0: Not used.
1: Used.
If an axis is set to be not used, then that axis will not be controlled and IW††00
to IW††3F monitoring parameters will not be updated. “0” will stored at
IW††00 RUN Status. 0
(Not used)
2 PG Signal Form Se-
lections (PGSEL) Set the form and polarity of the PG input signal. −
Bits 0 to 7 Not used. − −
Bit 8 Pulse-A/B Input Sig-
nal Polarity Selec-
tion (ABPISEL) Set the polarity of the pulse-A/B input signal.
0: Positive logic
1: Negative logic 0
(Positive
logic)
Bit 9 Pulse-C Input Signal
Polarity Selection
(CPISEL) Set the polarity of the pulse-C input signal.
0: Positive logic
1: Negative logic 0
(Positive
logic)
Bits 10 to 15 Not used. − −
3 Encoder Selection
(ENCSEL) Set the type of encoder that is used.
0: Incremental encoder
1: Absolute encoder
2: Absolute encoder used as an incremental encoder. 0
(Incremental
encoder)
4 Rotation Direction
Selection with an
Absolute Encoder
(DIRINV) Set the rotation direction when using an absolute encoder.
0: Forward rotation selection
1: Reverse rotation selection
Set reverse rotation direction (= 1) in the following situations.
• When the DIR terminal of the SERVOPACK is connected to 0 V and reverse
rotation connection is selected when using an absolute encoder-compatible
SERVOPACK. Refer to the SERVOPACK operating manual for details on
reverse rotation connection with a SERVOPACK.
• When the Reverse Direction Selection (Cn30 bit 8) of the VS-866 is set to ON
when using an absolute encoder-compatible VS-866. Reverse the PB0 connec-
tion to ensure the same phase relationship as the SERVOPACK. Refer to the
VS-866 user’s manual for details.
0
(Forward
rotation)
