Drive Characteristics

Over-current Protection

The G7 ASD has an over-current protective function to protect the motor and the drive. The default
setting for this function is the maximum rating of the drive.
When using the drive for an application that controls a motor which is rated significantly less than the
maximum current rating of the drive, the over-current limit (Thermal Overload Protection) setting will
have to be changed to match the application. For further information on this parameter, see
Thermal Protection #1 on pg.

Drive Capacity

The G7 ASD must not be used with a motor that has a significantly larger capacity, even if the motor is
operated under a small load. A drive being used in this way will be susceptible to the high-output peak
current which may result in nuisance tripping.
Do not apply a level of input voltage to a drive that is beyond that which the drive is rated. The input
voltage may be stepped down when required with the use of a step-down transformer or some other type
of voltage reduction system.
