Configuration
Special Purpose Variables
Table 5 contains VSD function codes that don’t have their own corresponding
network variables. These codes complement the function codes associated with the
configuration variables in Table 1. For example, the auto-start frequency fall rate
(H14 in Table 5) uses the value in the nciRampDownTm variable (F08 in Table 1) as
a reference.
The Interface Card gives lets you program these function codes with a PC instead of
the VSD keypad by using the following special purpose variables:
• QYL:ULWH3DUDP9DO
• QYL:ULWH3DUDP1XP
• QYL5HDG3DUDP1XP
• QYR5HDG3DUDP9DO
Use the index numbers in Table 5 to represent the VSD function codes.
