Electronic thermal O/L relay (Select)
This function is used to select between the following three values:
0 Inactive
1 Active············4-pole standard motor
2 Active············4-pole forced air motor
Electronic thermal O/L relay(Level)
0. 1 4
to

Set the value obtained by multiplying the motor rated current by coefficient K in the table below ac-
cording to the wiring length between the drive and motor.
Drive HP
0’ 132’ 165’ Max. 330’
1/8 K=1.2 External thermal is
recommended.
1/4 K=1 K=1.1
1/ 2 to 5 K=1
This function sets the operation level of an electronic thermal O/L relay by using an
ampere value according to the motor rated current.
20 to 135% of the drive rated current can be set.
Values less than 9.99A can be set in 0.01A step and values more than 10.0A can be set
in 0.1A step.
