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

Encoder 1 Rotation
Selection
Sets the output sequence for the A and B pulses from the encoder, assuming that the motor
is operating in the forward direction.
0 : Pulse A leads in FWD Direction
1 : Pulse B leads in FWD Direction

Encoder 1 Pulse Monitor
Scaling
Sets the ratio between the pulse input and the pulse output of the encoder as a 3-digit
number. The first digit is the numerator and the second and third digits set the denominator.
The dividing ratio = (1 + x)/yz when the setting value is a 3-digit value (xyz).

(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 [Maximum Speed]

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].

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]
