r.020, r.021, r.022 Outer Loop PI Regulator

(continued)

The RMI board provides the option to make the torque limit and current limit a function

of the RMI analog input or the RMI frequency input, depending on r.025. When the

RMI board is not present, there is no adjustable limit.

For vector regulation, the torque limit can be adjusted. For V/Hz regulation, the current

limit can be adjusted. The value of r.025 determines the source for the limit. When

r.025 = 0, the limit is set to 4095. When r.025 = 1 or 2, the limit comes from the RMI

board. This can be the RMI analog input or the RMI frequency input. The output of the

torque limit is normalized so that 4095 corresponds to 150%. The output of the current

limit is normalized so that 4095 corresponds to 200%.
