Programming D-56
890CS Common Bus Supply - Frames B & D; 890CD Common Bus Drive and 890SD Standalone Drive - Frames B, C & D
When set TRUE, the demanded volts are reduced to minimise energy consumption if the drive is operating in a steady state at
light load.

Table
These parameters provide 10 frequency points, which together with the USER VOLTAGE parameters, provide the user defined
voltage profile. (USER FREQ n, USER VOLTAGE n) provide up to 10 (x,y) points on this profile. The USER FREQ
parameters are defined as a percentage of the BASE FREQUENCY parameter (refer to the MOTOR
INDUCTION function
