5.3.2 Differences in Servo Connectors
The following table shows differences in servo connectors between the SVA-01A and SVA-
02A Modules.
Hardware
Specifica-
tions
(cont’d) External I/O Inputs 6 points for each axis None
• The general DI points of servo
connectors are used for the
OTR, OTF, and EXT.
• Allocate the DEC, RI, and RIC
to the LIO Module.
• ZERO cannot be used.
• OTF
• OTR
• DEC • ZERO
• EXT
• RI
1 common point for reserve
• RIC
Outputs 2 points for each axis None
• BRK OUT, RO, and ROC have
been deleted.
• BRK OUT • RO
1 common point for reserve
• ROC
Absolute Battery
Inputs Battery inputs from external interfaces
are output to SERVOPACKs via servo
connectors 1CN to 4CN. Connect the battery power supply
directly to SERVOPACKs.
+24 V Inputs for Ser-
vo I/O +24 inputs from external interfaces are
output to SERVOPACKs via servo con-
nectors 1CN to 4CN. Connect the +24 V input connector to
the 3CN connector.
