• Set of accel/decel times can be switched by turning ON/OFF the
accel/decel command terminals if input terminal function selection
(H0.02~H0.05) is set to "accel/decel command".
When OFF: F2.01 (accel time 1), F2.02 (decel time 1)
When ON : F2.03 (accel time 2), F2.04 (decel time 2)
Acceleration time: Time required for output frequency to reach
from 0% to 100%.
Deceleration time: Time required for output frequency to reach
from 100% to 0%.
Holding accel/decel (Setting : 10)
OFF Normal operation or restart accel/decel.
ON Holds accel/decel and maintain the present frequency.
• The output frequency can be hold when the accel/decel holding
terminal is ON.
• The output frequency can be kept when the accel/decel holding
terminal is OFF.

• With these settings, the inverter's output frequency can be controlled
by the multi-function inputs.
• Both setting 12 and 13 must be set when using this function.
• This function will operate only when B0.02(
1(
Contact input: contact 1 or 2 on terminal block)
• The upper and lower limits for the output frequency with the up/down
commands are as follows:
- Upper limit=Max. output frequency(C0.02)¡ ¿ High speed limit(F1.01)/100
- Lower limit=Max. output frequency(C0.02)¡ ¿ Low speed limit(F1.02)/100
• If a run command is input, the output frequency will be accelerated to
the lower limit when this function is used.
• If the up/down function is set, the multi-step commands 1 to 8 are
disabled.
