to set the drive’s output current limit. When the drive is in VF, SVC or VFPG control mode, output
frequency will decreases as the output current reaches current limit. It is a current stall prevention.
Electronic Thermal Relay Selection (Motor 1)
Electronic Thermal Relay Selection (Motor 2)
Factory Setting: 2
Settings
0: Constant torque output motor
1: Variable torque output motor
2: Disable
It is used to prevent self-cooled motor overheats under low speed. User can use electronic thermal
relay to limit driver’s output power.
Electronic Thermal Characteristic for Motor 1
Electronic Thermal Characteristic for Motor 2
Factory Setting: 60.0
Settings 30.0~600.0 sec
The parameter is set by the 150% of motor rated current and the setting of Pr.06-14 and Pr.06-28 to
prevent the motor damaged from overheating. When it reaches the setting, it will display
“EoL1/EoL2” and the motor will be in free running.

Pr.06-15 sets the heatsink temperature level of the drive. The drive will output an overheating
warning when the temperature exceeds the setting of Pr.06-15. If the setting of Pr.06-15 is higher
than the default setting of the drive, the drive will use the default setting level for warning output.
Capacitor (CAP) overheating level is set by the drive’s default setting, it can not be adjusted.
