Bulletin

160 SSC

Specific

Extensions

The AC Drive Object includes in its implementation a variable number of 160 SSC specific instance attributes. By adding the number 100 to
any parameter number in the Bulletin 160 parameter table, the resulting number will be a 160 SSC specific instance attribute in the AC Drive
Object. For example, in the 160 SSC drive, parameter 5 displays Bus Voltage. Therefore, attribute # 105 of the AC Drive Object returns Bus
Voltage. This method of extending the AC Drive Object allows for an ODVA compliant implementation of the Drive Profile, and accommo-
dates all Bulletin 160 SSC models (both analog and preset speed models). Refer to the Bulletin 160 SSC User Manual, Chapter 5.
