Encoder Signal Loss Detect
Sel
Sets the method to stop the motor or let the motor continue operating when the drive detects PGo
[Encoder (PG) Feedback Loss].
0 : Ramp to Stop
1 : Coast to Stop
2 : Fast Stop (Use C1-09)
3 : Alarm Only
4 : No Alarm Display
Note:
When A1-02 = 0 [Control Method Selection = V/f], set H6-01 = 3 [Terminal RP Pulse Train
Function = Speed Feedback (V/F Control)] to enable this parameter.

Overspeed Detection
Selection
Sets the method to stop the motor or let the motor continue to operate when the drive detects oS
[Overspeed].
0 : Ramp to Stop
1 : Coast to Stop
2 : Fast Stop (Use C1-09)
3 : Alarm Only
Note:
When A1-02 = 0 [Control Method Selection = V/f], set H6-01 = 3 [Terminal RP Pulse Train
Function = Speed Feedback (V/F Control)] to enable this parameter.

Speed Deviation Detection
Select
Sets the method to stop the motor or let the motor continue to operate when the drive detects dEv
[Speed Deviation].
0 : Ramp to Stop
1 : Coast to Stop
2 : Fast Stop (Use C1-09)
3 : Alarm Only
Note:
When A1-02 = 0 [Control Method Selection = V/f], set H6-01 = 3 [Terminal RP Pulse Train
Function = Speed Feedback (V/F Control)] to enable this parameter.

(0387)
Overspeed Detection Level
Sets the detection level of oS [Overspeed] as a percentage when the maximum output frequency is
100%.
Note:
• Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output
frequency.
–A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
–A1-02 = 8: E9-02 [Motor Max Revolutions]
• When A1-02 = 0 [Control Method Selection = V/f], set H6-01 = 3 [Terminal RP Pulse Train
Function = Speed Feedback (V/F Control)] to enable this parameter.

Overspeed Detection Delay
Time
Sets the length of time that the speed feedback must be more than the F1-08 level to cause oS
[Overspeed].
Note:
When A1-02 = 0 [Control Method Selection = V/f], set H6-01 = 3 [Terminal RP Pulse Train
Function = Speed Feedback (V/F Control)] to enable this parameter.

Speed Deviation Detection
Level
Sets the detection level of dEv [Speed Deviation] as a percentage when the maximum output
frequency is 100%.
Note:
• Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output
frequency.
–A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
–A1-02 = 8: E9-02 [Maximum Speed]
• When A1-02 = 0 [Control Method Selection = V/f], set H6-01 = 3 [Terminal RP Pulse Train
Function = Speed Feedback (V/F Control)] to enable this parameter.
