b 8 - 0 1 : Energy Saving Gain
This parameter is only available in the V/f or V/f w/PG Control Methods (A 1 - 0 2 = 0 or 1).
This parameter sets, in increments of 1%, the level to which the output voltage is reduced
during the energy-saving operation.

Output Voltage During Energy-Saving Operation
b 8 - 0 2 : Energy Saving Frequency
This parameter is only available in the V/f or V/f w/PG control methods (A 1 - 0 2 = 0 or 1).
The energy saving function will only activate if all of the following conditions are met: a
multi-function input is activated which is set to energy savings (data 6 3), output frequency
is above the Energy Saving Frequency b 8 - 0 2, and the drive is up to its set speed (output
frequency = frequency reference).
B . Energy Saving – Open Loop Vector &

1
This parameter is only available when in the open loop vector or flux vector control methods
( A 1 - 0 2 = 2 or 3). When b 8 - 0 3 is set to a 1, a multi-function contact input is n o t required
to activate energy saving mode. This function is separate and should not be confused with
parameters b 8 - 0 1 and b 8 - 0 2. When the drive detects a lightly loaded motor, the output
voltage will automatically be reduced.
