b 8 - 0 4 : Automatic Energy Saving
Control Gain
b 8 - 0 5 : Automatic Energy Saving
Control Time Constant
These parameters are only available when in the open loop vector or flux vector control
methods (A 1 - 0 2 = 2 or 3). Parameters b 8 - 0 4 and b 8 - 0 5 adjust the energy savings
voltage regulator. Increasing the gain (b 8 - 0 4) and/or decreasing the time constant (b 8 -
0 5) will increase the responsiveness of the energy savings function. If the response is set
too fast, the drive may become unstable. If the response is set too slow, the drive may
respond incorrectly when the motor load is re-applied.
H 1 - 0 1 thru H 1 - 0 6 : Multi-function
Inputs (Term. 3 thru 8)
A multi-function input must be used to
command energy saving operation.
When the external Energy-Saving Operation
command is closed at set frequency, the energy-
saving operation shown below is enabled. In the
energy saving operation, the output voltage is the
value of the energy saving gain ( b 8 - 0 1; factory
set to 80%) multiplied by the V constants defined
by E 1 - 0 5, - 0 8 and - 1 0 .
NOTE
If energy saving operation is enabled before accel
time is complete, output V/Hz is not affected until
set frequency is reached; then output voltage is
reduced by energy-saving gain ( b 8 - 0 1 ) setting.
