Parameter E0.74 is used to control the acceleration / deceleration speed inside
the skip-window, the range for this factor is 1 (normal speed) to 100 (100 times
speed of the normal speed).
The actual acceleration / deceleration time for skip frequency is
shorter than the setting value when the factor is higher than 1.
12.6.2 Jog Function
The 'Jog command' has a higher priority than and is independent of the 'Run /
Stop command'. This function can ONLY be set by digital input or communica-
tion. To use this function, take the following steps:

Once the 'Jog command' is active, the frequency converter runs immediately to
[E0.60] 'Jog frequency' with acceleration / deceleration time defined by 'Jog ac-
celeration time' [E0.61] / 'Jog deceleration time' [E0.62] no matter the convert-
er is running or not. When 'Jog command' is inactive, the motor resumes the
previous status.
●
Converter is at stop
– 'Jog command' active: Accelerate to [E0.60] 'Jog frequency' according to
[E0.61] 'Jog acceleration time'.
– 'Jog command' inactive: Deceleration time is according to [E0.62] 'Jog de-
celeration time'.
●
Converter is running
– 'Output frequency' is higher than 'Jog frequency'
– 'Jog command' active: Decelerate to [E0.60] 'Jog frequency' according
to [E0.62] 'Jog deceleration time'.
– 'Jog command' inactive: Accelerate to previous 'Setting frequency' ac-
cording to [E0.26] 'Acceleration time'.
– 'Output frequency' is lower than 'Jog frequency'
