FUNCTION C
ODES
F07, F08 Acceleration Time 1, Deceleration Time 1
E10, E12, E14 (Acceleration Time 2, 3 and 4)
E11, E13, E15 (Deceleration Time 2, 3 and 4)
H07 (Acceleration/Deceleration Pattern)
H56 (Deceleration Time for Forced Stop)
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.
- Data setting range: 0.00 to 3600.00 (s)

Acceleration/

E14 E15 ON ON
The combinations of ON/OFF states of
the two terminal commands
RT2 and
RT1 offer four choices of acceleration/
deceleration time 1 to 4. (Data = 4, 5)
If no terminal command is assigned,
only the acceleration/deceleration time 1
(F07/F08) is effective.
Force to stop - H56
If terminal command STOP (data = 30) is turned OFF, the
inverter decelerates to a stop with the deceleration time
specified by H56. After that, the inverter displays alarm Er6
and enters an alarm state.

Acceleration/Deceleration pattern (H07)
H07 specifies the acceleration and deceleration patterns (patterns to control output
frequency).

code
0 Linear
The inverter runs the motor with the constant acceleration and
deceleration.
-
1
S-curve
(Weak) Weak:
The acceleration/deceleration rate to
be applied to all of the four
inflection zones is fixed at 5% of the
maximum frequency.
-
2
S-curve
(Strong)
To reduce an impact that
acceleration/deceleration
would make on the machine,
the inverter gradually
accelerates or decelerates the
motor in both the starting
and ending zones of
acceleration or deceleration.
Strong:
The acceleration/deceleration rate to
be applied to all of the four
inflection zones is fixed at 10% of
the maximum frequency.
-
3
Curvilinear
Acceleration/deceleration is linear below the base frequency
(constant torque) but it slows down above the base frequency to
maintain a certain level of load factor (constant output).
This acceleration/deceleration pattern allows the motor to accelerate
or decelerate with the maximum performance of the motor.
