About this Manual
This manual describes information required for designing, testing, adjusting, and maintaining large-capacity
models of servo systems in the Σ-V series.
Keep this manual in a location where it can be accessed for reference whenever required. Manuals outlined on
the following page must also be used as required by the application.
Differences between Large-capacity Σ-V SERVOPACKs and Standard Σ-V
SERVOPACKs
The differences between the large-capacity Σ-V SERVOPACKs and the standard Σ-V SERVOPACKs are
described below. Equipment damage may occur if these items are used or set incorrectly.
• CN1 Connector
The number of pins on the CN1 connector is different on a large-capacity Σ-V SERVOPACK (50 pins) and
a standard Σ-V SERVOPACK (26 pins).
If you are using both types of SERVOPACK, use the correct connector model numbers when ordering and
the correct signal assignments.
• Factory Settings of Parameters
The factory settings of the following parameters are different: Pn50A.3, Pn50B.0, and Pn511.0.
Make sure that you consider any differences in the factory settings if you copy the parameters from a stan-
dard Σ-V SERVOPACK to a large-capacity Σ-V SERVOPACK.
For details, refer to 3.4.1 Input Signal Allocations.
• Monitor Displays
The monitor display digits are different for P-OT, N-OT, and /DEC.
Make sure you are reading the displays correctly when checking signal operation.
For details, refer to 7.3 Monitoring Input Signals.
