F1-10
Excessive
Speed
Deviation
Detection
Level
Configures the speed
deviation fault (DEV)
detection.
DEV fault will occur if the
speed deviation is greater
than the F1-10 setting for a
time longer than F1-11. F1-10
is set as a percentage of the
maximum output frequency
(E1-04).
Speed deviation is the
difference between actual
motor speed and the
frequency reference
command. See F1-04.

Sets the gear ratio between
the motor shaft and the
encoder (PG).
A gear ratio of 1 will be used
if either of these parameters is
set to 0. This function is not
available in flux vector con-
trol.

Parameter 2
Sets the PG pulse count for
