Light-load Acceleration 2 Fault (OL6) Protection Operation (S4-14) 

 

Setting 

Operations after Detection  

Fault Type  

0 

Deceleration to stop (Deceleration by selected deceleration time) 

Major fault (fault  contact output is enabled.)  

1 

Coast to stop 

Major fault (fault contact output is enabled.)  

2 

Deceleration to stop (Deceleration by fast stop time.) 

Major fault (fault contact output is enabled.)  

3 

Acceleration prohibited (Operation continues) 

Minor fault (reset when run command is opened and stopped.) 

*All are detected  during run only. 

 

When the setting value is 0, 1, or 2: 

“O16” will flash on the operator screen until the reset command input is pushed after Light-load 2 Fault has been 

detected. 

 

When the Setting Value is 3: 

“O16” will flash on the operator screen until the motor comes to a complete stop and the Run 
Command relay is opened if a Light-load 2 Fault is detected. 

  

 

Note: When the setting value is “ 3” (Minor Error Setting), then “OL6” will continue flashing 

on the operator screen, even if the RESET key is depressed.  

 
 

6.5 Overload Detection  

Limits drive operations (Safety Procedures) based on the the torque reference for the drive or the size of the output 

current.  This limit is set by adjusting parameter values.  Detection operations and detection levels can be set in two 
groups: 

When parameter b1-02 equals zero (Operator Operation), Overload Detection will not operate.

 

No. 

Name  

Description 

S5-01   Overweight Detection 

Operation Selection 1  

Enables and disables overload detection, determines the conditions for detection, and the operations that follow 

detection. 
 
0: No overload detection. 
1: Detection only during Speed Agree, acceleration prohibited  (continue running).  Minor error.  
2: Detection while running, acceleration prohibited  (continue running). Minor error. 
3: Detection only during Speed Agree.  Decelerate to stop at Fast Stop Time (C1 -09).  Minor error.  
4: Detection during run. Decelerate to stop at Fast Stop Time (C1 -09).  Minor error.  
5: Detection only during Speed Agree.  Interrupt output current. Serious error.  
6: Detection during run. Interrupt output current. Serious error.  

     Setting Value is 1 or 2: 

After overload detection conditions arise, "OL5" will flash on the operator screen until the Run Command relay 

opens and the motor stops.  

Setting Value is 3 or 4: 

After overload detection occurs, the drive will stop. The Run Command input relay is opened, and "OL5" will 

flash on the screen until the relay is closed again. Once closed, the drive will start to run again. 

Setting Value is 5 or 6: 

"OL5" will flash on the operator screen after overload detection until the fault reset is triggered.  

Note:  With settings 1~4 (minor errors), the operator screen will continue to flash "OL5" even if the RESET key 

is depressed. 

S5-02  Overweight Detection 

Level 1 

Sets the Overload Detection Level: 

・

 

In V/f Control Mode, the motor rated current is 100% 

・

 

In Vector Control Mode, the motor rated torque is 100%. 

S5-03  Overweight Detection  

Time 1 

If the time by which motor current or torque exceeds the value set to S5 -02 is longer than the value set in this 

parameter, then an overweight detection relay is tripped.  

S5-04  Overweight Detection 

Operation Selection 2  

Same as S5 -01. 

S5-05  Overweight Detection 

Level 2 

Same as S5 -02 

S5-06  Overweight Detection  

Time 2 

If the time for the motor current or motor torque set by S5 -05 is longer than the time set in this parameter, then 

overweight will be detected.  

If overload detection has been set to Multi-Function Output (setting = 22 or 23), then the relay is triggered.  See 

the table below for the conditions when the relay is open or closed.
