Electronic Thermal Reference Current
Setting range
0.0 to
(see note 1) (A)
Factory setting
See note 2
Unit of setting
0.1 (A)
•
This constant is used to set an electronic thermal reference value to protect the motor
from overheating.
Set the rated motor amperage in this constant.
•
If 0.0 is set in this constant, “no thermal protection” is assumed, so motor overload will
not be detected.
•
The setting range and factory setting for this constant are as follows:
3E3EV- Maximum applicable

A2015R 1.5 kW 8.4 (A) 6.2 (A)
Stall Prevention during Deceleration
Setting range
0, 1
Factory setting
0
This constant is used to select the action to prevent overvoltage during deceleration.
Value Description
0 Stall prevention during deceleration
1 No stall prevention during deceleration
Note 1.
Ifabraking resistor is to be connected, always set“1” (no stall prevention during
deceleration) in this constant.
