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
accommodates all Bulletin 160 SSC models (both analog and preset speed models). Refer to the Bulletin 160 SSC User Manual, Chapter 5.
