Preparing for Operation
n31
Electronic Thermal Reference Current
Setting range
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.
n32
Electronic Thermal Protection
Setting range
•This constant is used to set an electronic thermal characteristic.
•If 4 is set in this constant, "no thermal protection" is assumed, so motor overload will not
be detected.
Value
0 Standard motor with standard ratings
1 Standard motor with short-time ratings
2 Dedicated motor with standard ratings
3 Dedicated motor with short-time ratings
4 No thermal protection
Note If a single Inverter is used to operate more than one motor, 4 must be set in n32 or
0.0 must be set n31 and a thermal relay must be connected to each of the motors.
n33
Stall Prevention During Deceleration
Setting range
This constant is used to select the action to prevent overvoltage during deceleration.
Value
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.
