When there is no assignment,
acceleration/deceleration time 1 (F07, F08)
are valid.

When ready for jogging “JOG” is ON, switch to the mode with which
jogging operation is possible (data = 10) ( function code C20).
When performing
forced stop
-
H56
Turning the forced stop “STOP” command OFF causes the motor to
decelerate to a stop in accordance with the deceleration time for forced
stop (H56).
After the motor stops, the inverter enters the alarm state with the alarm
er6 displayed (data = 30).
 Curve acceleration/deceleration (H07)
Select acceleration/deceleration pattern (change pattern of frequency) at acceleration/deceleration.

S-curve
acceleration/deceleration
(Weak)
Smoothen the speed
change and reduce shock
when starting acceleration
and right before the speed
becomes constant, as well
as when starting
deceleration and right before
the deceleration stops.
Weak: Fix acceleration/deceleration
change rate to 5% of the maximum output
frequency within each S-curve range.

S-curve
acceleration/deceleration
(Arbitrary)
Arbitrary: It is possible to set
acceleration/deceleration change rate
arbitrarily within each S-curve range.

Curve
acceleration/deceleration
Linear acceleration/deceleration (constant torque) at or below base
frequency and acceleration becomes gradually slower at or higher than
the base frequency, and acceleration/deceleration with constant load rate
(rated output).
It is possible to accelerate/decelerate with the maximum capability.
-
S-curve acceleration/deceleration
For the purpose of decreasing the shock on the load machine side, smoothen the speed change at the start of
acceleration and right before it becomes constant speed, and at the start of deceleration and right before the stop
of deceleration. As for s-curve acceleration/deceleration values, fix with 5 % for S-curve acceleration/deceleration
(weak), and for S-curve acceleration/deceleration (arbitrary), it is possible to set individually for each 4 locations by
function codes H57 to 60. The specified acceleration/deceleration time determines acceleration of linear part and
the actual acceleration/deceleration time becomes longer than the specified acceleration /deceleration time.
