Deceleration to stop using deceleration time 1 (C1-02).
1 Coast to stop
2 Emergency stop using the emergency-stop time (C1-09).

Continue operation (Display “DEV” and continue control.)
4 Deceleration t to stop using deceler action time 1 ( c1 − 02)*2
5 Coast to stop *2
6 Emergency stop using the emergency − stop time (c1 − 09)*2
7 Continue Operation (Displays ”DEV” and continues control )*2
* 1. Speed agreement conditions: The frequency reference and output frequency were entered
in the speed agree detection width set in L4 − 02.
* 2. Speed agreement conditions: The frequency reference and the (actual) motor speed based
on the PG feedback value were entered in the speed agree detection width set in L4 − 02.
D
F1-10 and F1-11 Settings
Constant F1-10 sets the PG speed deviation detection level as a percentage of the maximum output
frequency. Constant F1-11 sets the length of time in seconds that the difference between the motor
speed and reference speed must exceed the PG speed deviation detection level in order to detect a PG
speed deviation (DEV).

Gain Settings
D
When using “V/f control with PG feedback,” set the gain at the minimum output frequency and maxi-
mum output frequency.
Max. Output Frequency Gain Settings: C5-01, C5-02
D
Set the proportional gain (C5-01) and the integral time (C5-02) of the speed control (ASR).
