0 General-purpose motor, standard rating (8 min.)
1 General-purpose motor, short-term rating (5 min.)
2 Blower-cooled motor, standard rating (8 min.)
3 Blower-cooled motor, short-term rating (5 min.)
4 Electronic thermal overload protection disabled
The GPD 205 protects against motor overload with a UL-recognized, built-in
electronic thermal overload relay.
The electronic thermal overload function monitors motor temperature, based on drive
output current and time, to protect the motor from overheating. When the electronic
thermal overload trips, an “ o
o L L 1 1 ” error occurs, shutting OFF the drive output and
preventing excessive overheating in the motor. When operating with one drive
connected to only one motor, an external thermal relay is not needed. When
operating several motors with one drive, install a thermal overload relay on each
motor.

Induction motors are classified as general-purpose or blower-cooled motors, based on
their cooling capabilities; the motor overload detection function operates differently,
as shown, for each of these two motor types.
