S A voltage change rate can be set according to the output voltage of the Inverter.
S Set
n101 and n102 to values smaller than the default-set values if it is necessary to minimize the
speed ripples of the motor.

H Effective Energy-saving Control
Take the following steps to check whether the Inverter in energy-saving mode is saving unnecessary
power supply to the motor.
1. Output Power
Press
the ENERGY SA
VE Key and POWER Key to check whether the output power of the Inverter
in energy-saving mode is lower than that of the Inverter not in energy-saving mode.
2. Motor
Check
that the motor does not stall
or vibrate error when the Inverter performs energy-saving con
-
trol.
H Troubleshooting of Energy-saving Control Problems
If the Inverter in energy-saving mode stalls the motor, vibrates the motor, or does not
save unnecessary power supply to the motor, refer to the following table to check the
probable cause of the trouble and take countermeasures against the trouble.
Running
conditions of the motor may inhibit the Inverter from performing ef
fective ener
-
gy-saving control.
Problem Probable cause Remarks
Output power does not
change
Inverter is running at a
frequency exceeding 120 Hz
The Inverter does not save unnecessary
power supply to the motor while the
Inverter is running at a frequency
exceeding 120 Hz.
