OMRON Sysdrive 3G3HV - Detector Cooling Section

The Inverter calculates its mean output power during the time set with n099 for the energy-saving
control of the motor.
The time set with n099 is used as a search operation period, in which the output voltage of
the Inverter in search operation mode changes.
Set n099 to a value larger than the default-set value if the load factor of the motor changes
greatly or the friction factor of the load is large and the motor vibrates.

Set Values
The values set with n101 and n102 are used as voltage change rates, at which the output
voltage of the Inverter in search operation mode changes.
It is usually not necessary to change the default-set values of n101 and n102.
A voltage change rate can be set according to the output voltage of the Inverter.
Set n101 and n102 to values smaller than the default-set values if it is necessary to minimize
the speed ripples of the motor.

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.
Output Power
Press the ENERGY SAVE 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.
Motor
Check that the motor does not stall or vibrate error when the Inverter performs energy-saving
control.
Troubleshooting of Energy-saving Control Problems
If the Inverter in energy-saving mode stalls the motor, vibrates the motor, or
