Energy-saving
To
perform energy saving, set b8-01 (Energy Saving Mode Selection) to 1. Energy-saving control can be per-
formed
using both V/f control and open loop vector control. The parameters to be adjusted are different for
each.
In V/f control, adjust b8-04 to b8-06, and in open loop vector, adjust b8-02 and b8-03.

Parameters
* 1. The
factory setting is 1.0 when using V/f control with PG.
* 2. The
factory setting is 2.00 s for an Inverter capacity of 55 kW and over.
* 3. The
same capacity as the Inverter will be set by initializing the parameters.
* 4. The
factory settings depend on the Inverter capacity.
* 5. The
factory settings depend on the Inverter capacity. (The values shown are for 200-V class, 0.4 kW Inverters.)
