Parameter Descriptions
ENERGY SAVING
PREF: 21.09
Default: FALSE
Range: FALSE / TRUE
When set TRUE, the demanded volts are reduced to minimise energy consumption if the drive is operating in a steady state at
light load.
USER FREQ 1 to 10
PREF: 21.10, 21.12, 21.14,
21.16, 21.18, 21.20, 21.22,
21.24, 21.26,21.28
Default: Refer to Parameter
Table
Range: 0.0 to 100.0 %
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
block).
USER VOLTAGE 1 to 10
PREF: 21.9, 21.11, 21.13,
21.15, 21.17, 21.19, 21.21,
21.23, 21.25,21.27, 21.29
Default: Refer to Parameter
Table
Range: 0.0 to 100.0 %
These parameters provide 10 voltage points, which together with the USER FREQ 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 VOLTAGE parameters
are defined as a percentage of the MOTOR VOLTAGE parameter (refer to the MOTOR INDUCTION function block).
