Yaskawa VS-626 MC5 - Manual (Page 127)

Basic Operation
6.3.1 PG Speed Control Card Settings
- 24
Setting Function
2 Emergency stop using the emergency-stop time (C1-09).
3 Continue operation (PGO is displayed, and continues operation.)
Overspeed Settings: F1-03, F1-8, F1-09
D Overspeed refers to an excessive motor speed.
D Set the conditions (level and time) for detecting overspeed and the stopping method that is used when
an overspeed is detected.

Setting Function
0 Deceleration to stop using deceleration time 1 (C1-02).
1 Coast to stop
2 Emergency stop using the emergency-stop time (C1-09).
3 Continue operation (OS is displayed, and continues operation.)
D F1-08 and F1-09 Settings
Constant F1-08 sets the overspeed detection level as a percentage of the maximum output frequency.
Constant F1-09 sets the length of time in seconds that the motor speed must exceed the overspeed
detection level in order to generate an overspeed fault.
PG Speed Deviation Settings: F1-04, F1-10, F1-11
D PG speed deviation refers to the difference between the actual motor speed and the reference speed.
D These constants set the conditions (level and time) for detecting PG speed deviation and the stopping
method that is used when a PG speed deviation is detected.

2 Emergency stop using the emergency-stop time (C1-09).
3 Continue operation (Displays “DEV” and continues control.)
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).
