Output Terminal Functions
6-89
Motor 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-servo
operation 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 condition
ON
Enables 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-servo
command was input.
