V/f pattern with two non-linear points
F07
Acceleration Time 1
F08
Deceleration Time 1
E10 Acceleration Time 2
E11 Deceleration Time 2
F07 specifies the acceleration time, the length of time the frequency increases from 0 Hz to
the maximum frequency. F08 specifies the deceleration time, the length of time the frequency
decreases from the maximum frequency down to 0 Hz.
• Selecting an S-shaped pattern or curvilinear acceleration/deceleration pattern
with function code H07 (Acceleration/deceleration pattern) makes the actual
acceleration/deceleration times longer than the specified ones. Refer to the
descriptions of function code H07.
• Specifying an improperly short acceleration/deceleration time may activate the
current limiter or anti-regenerative control, resulting in a longer acceleration/
deceleration time than the specified one.
Acceleration/deceleration time 1 (F07, F08) and acceleration/deceleration time 2
(E10, E11) are switched by terminal command RT1 assigned to any of the
digital input terminals with any of function codes E01 through E03.
