Current Limit
Default:
Settings 230V / 460V models:
0–195% (100% corresponds to the rated
current of the drive)
190
575V / 690V models:
0–250% (100% corresponds to the rated
current of the drive)
170
 230V / 460V models: 100% corresponds to the rated current of the drive, refer to Pr.00-01 for
details.
 575V / 690V models: 100% corresponds to the rated current of the drive (Pr.00-01).
 Set the maximum output current of the drive. Use Pr.11-17–Pr.11-20 to set the drive’s output
current limit.

Electronic Thermal Relay Selection 1 (Motor 1)

06-27
Electronic Thermal Relay Selection 2 (Motor 2)
Default: 2
Settings 0: Inverter motor (with external forced cooling)
1: Standard motor (motor with fan on the shaft)
2: Disabled
 Prevent self-cooled motor from overheating under low speed. Use an electronic thermal relay to
limit the drive’s output power.
 Setting the parameter to 0 is suitable for an inverter motor (motor fan using an independent power
supply). For this kind of motor, there is no significant correlation between cooling capacity and
motor speed. Therefore, the action of electronic thermal relays remains stable in low speed to
ensure the load capability of the motor in low speed.
 Setting the parameter to 1 is suitable for standard motor (motor fan is fixed on the rotor shaft). For
this kind of motor, the cooling capacity is lower in low speed; therefore, the action of an electronic
thermal relay reduces the action time to ensure the life of motor.
 When the power is cycled frequently, if the power is switched OFF, the electronic thermal relay
protection is reset; therefore, even setting the parameter to 0 or 1 may not protect the motor well.
If there are several motors connected to one drive, install an electronic thermal relay in each motor.

06-28
Electronic Thermal Relay Action Time 2 (Motor 2)
Default: 60.0
Settings 30.0–600.0 sec.
 Set the parameter to 150% of motor rated current and use with the setting of Pr.06-14 and Pr.06-
28 to prevent motor damage due to overheating. When it reaches the setting, the drive displays
“EoL1 / EoL2”, and the motor coasts to stop.
