Setting Motor Rated Current
Set the rated current value on the motor nameplate in parameters E2-01 (for motor 1) and E4-01 (for motor 2).
This set value is the electronic thermal base current.
Setting Motor Overload Protection Characteristics
Set the overload protection function in L1-01 according to the applicable motor.
The induction motor's cooling abilities differ according to the speed control range. Consequently, you must
select the electronic thermal protection characteristics to match the applicable motor's tolerance load charac-
teristics.
The following table shows the motor type and tolerance load characteristics.

General-purpose
motor (standard
motor)
Use this motor for
operations using a
commercial power
supply. This motor
construction yields
best cooling effect
when operating at 50/
60 Hz.
When operating continu-
ously at 50/60Hz or less,
motor overload detection
(OL1) is detected. The
Drive outputs the error
contact, and the motor
coasts to a stop.
2
Drive motor
(constant torque)
(1:10)
This motor yields a
cooling effect even
when operating at
low speeds (approx.
6Hz).
Operates continuously at 6
to 50/60Hz.
3
Vector motor
(1:100)
This motor yields a
cooling effect even
when operating at
extremely low speeds
(approx. 0.6Hz).
Operates continuously at
0.6 to 60Hz.
