Output Terminal Functions6- 89Motor Overload (OL1) Pre-alarm (Setting: 1F)• This output function is valid when the motor overload protection function is enabled (L1-01 =1).• This output can be used to warn of overheating before the protection function itself operates.Inverter Overheat (OH) Pre-alarm (Setting: 20)• This output function indicates that the temperature of the cooling fins reaches the temperature set in L8-02(the Inverter overheating alarm detection level).Speed reference limit (Setting: 31) (SPEC: E or later only)Zero-servo End (Setting: 33) (SPEC: E or later only)• This output function indicates that zero-servo position control has been completed.• The output is turned ON after the zero-servo command is input and the difference between the zero-servooperation starting position and the current position is within the zero-servo completion width (b9-02).OFF The motor protection function's electronic thermal value is less than 90% of the detection level.ON The motor protection function's electronic thermal value is greater than 90% of the detection level.OFF The cooling fin temperature is less than the "OH Pre-Alarm Level" set in L8-02.ON The cooling fin temperature exceeds the "OH Pre-Alarm Level" set in L8-02.OFF Other than ON conditionONEnables the speed reference limit in the following conditions (During flux vector control method):1. Frequency reference ≥ Frequency reference upper limit (d2-01)Frequency reference ≤ Frequency reference lower limit (d2-02)Frequency reference ≥ Output frequency lower limit of the multi-function analog input(Setting: 9)2. The frequency reference is less than the Min. output frequency (E1-09), and b1-05 is set to 1,2, or 3.OFF The zero-servo command isn't being input or zero-servo position control hasn't been completed.ON The position has been brought within the zero-servo completion width (b9-02) after the zero-servocommand was input.
