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:
Note 1. This can be set to a maximum of 120% of the Inverter rated current.
Note 2. Set to the normal rated current of the maximum applicable motor.
n33
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. If a braking resistor is to be connected, always set “1” (no stall prevention during
deceleration) in this constant.
Note 2. If “0” (stall prevention during deceleration) is set in this constant, deceleration
time will be automatically lengthened to prevent overvoltage.
