Section F: Option Parameters
F1 PG Option Set-up
F1-05 PG Rotation Selection
Sets the relationship between the motor rotation direction and PG polarity. (Hall sen-
sor HS4 & HS5 or encoder channel A & B).
The motor's rotation direction applies when viewing the motor shaft from the load
side.
F1-08 Overspeed Detection Level
Setting Range:
Factory Default:
This parameter sets the motor overspeed detection level as a percentage of maxi-
mum output speed (E1-06). Used in conjunction with parameter F1-09 to sense an
overspeed condition.
F1-09 Overspeed Detection Time
Setting Range:
Factory Default:
Sets the elapsed time from when an overspeed condition is detected to when a fault
(or alarm) occurs.
Overspeed Level (F1-08)
Overspeed Fault Signal
A fault signal is output to stop operation after the absolute value of the motor speed
exceeds the set value of F1-08 for the time set to F1-09. The stopping method is set
by F1-03.
