5.3.4 Precautions on Connecting the SVA-02A Module
Observe the following precautions when connecting the SVA-02A Module.
• Connect the 24-V servo I/O power supply to the CN3 connector.
• Connect the absolute encoder battery power supply directly to the SERVOPACK.
• Connect the OTF, OTR, and EXT signal terminals to the general-purpose input terminals
on the servo connector.
• Output brake output (BRK) signals directly from the SERVOPACK to the brake.
• Zero point latch input (ZERO) signals are not used with the SVA-02A Module.
• Connect the deceleration limit (DEC) signal terminal to the LIO or DI Module, and set it
in OB††01F, using ladder logic programming.
„ Overtravel Function for SVA-02A Module
Note the following items when using the overtravel function for the SVA-02A Module.
• Set bits 13 (Positive Overtravel Selection) and 14 (Negative Overtravel Selection) of fixed param-
eter No. 17 (Motion Controller Function Selection Flags) to 1 (Enabled).
• Connect the OTF and OTR signal terminals to the general-purpose input terminals of the CN1 and
CN2 servo connectors.
With the standard cables, the OTF and OTR signal terminals are also connected to the P-OT and
N-OT terminals on the SERVOPACK. Therefore, overtravel processing for the SVA-02A Module
is performed in the same way as for the SVA-01A Module.
