08- 05 Selection for motor overload protection (OL1)
Range
【xxx0b】：Motor overload is disabled
【xxx1b】：Motor overload is enabled
【xx0xb】：Cold start of motor overload
【xx1xb】：Hot start of motor overload
【x0xxb】：Standard motor
【x1xxb】：Special motor
【0xxxb】：Reserved
【1xxxb】：Reserved
(1) Please set motor overload protection function by parameter 08-05 according to currently
motor.
(2) Turn off the motor overload protection when using two or more motors connected to the
inverter (set 08-05=xxx0b), and provide external overload protection for each motor
(3) With hot start enabled (08-05=xx1xb), motor overload protection occurs in 3 and a half minutes
when operating the motor at 150% of the motor rated current at an output frequency greater
than 60Hz.
(4) When 08-05=x0xxb, overload protection function is based on 70% of the motor rated current
for an output frequency of 20Hz. If the output frequency is lower than 1Hz, the overload
protection function uses 40% of the motor rated current to determine an overload condition.
(5) When 08-05=x1xxb, overload protection function is based on motor rated current for output
frequencies between 6 and 60Hz. If the output frequency is lower than 1Hz, the overload
protection function uses 83% of the motor rated current to determine an overload condition.
(6) To use the built-in motor overload protection function parameter 02-01 (motor rated current)
has to match the motor rated current on the motor nameplate.
08- 06 Start-up mode of overload protection operation (OL1)
Range
【0】：Stop output after overload protection
【1】：Continuous operation after overload protection.
 08-06=0：When the inverter detects a motor overload the inverter output is turned off and the
OL1 fault message will flash on the keypad. Press RESET button on the keypad or
activate the reset function through the multi-function inputs to reset the OL1 fault.
 08-06=1：When the inverter detects a motor overload the inverter will continue running and
the OL1 alarm message will flash on the keypad until the motor current falls within
the normal operating range.
08- 07 Over heat protection (Cooling fan control)
Range
【0】：Auto (Depends on temperature)
【1】：Operate while in Run Mode
【2】：Always Run
【3】：Stop Operation
08 - 38 Delay Time of Fan Off
Range 【0 ~ 600】
 Over heat protection (Cooling fan control) (08-07)
(1) When 08-07=0, the inverter start to run, when heat sink temperature is higher than setting
level, the fan start to run. If the temperature drops period higher than 08-38, the fan stop.
