[Multi-Step Speed Operation]
n
Note: [I/O 12] (Jog Frequency) can be used as one of the
step frequencies.
n Note: If the ‘Jog’ terminal is ON, inverter operates at the
Jog frequency regardless of other terminal inputs.
JOG:
Jog Frequency can be used as one of the step
frequencies. Jog frequency is set in I/O 12.
ACCT_L, ACCT_M, ACCT_H:
[Multi-Step
Acceleration/Deceleration Time]
By setting multi-function input terminals to
‘ACCT_L’, ‘ACCT_M’ and ‘ACCT_H’
respectively, up to 7 different Accel and Decel times
can be used. The Accel/Decel time is set in [I/O 20]
through [I/O 33]
The Accel/Decel time is determined by the
combination of multi-function input terminals as
shown in the following table.

The Time 0 Accel/Decel time is configured by DRV
01-02 and selected when no Accel/Decel input
terminals are active.
Example:
If P4 is configured as ACC_L, P5 as ACCT_M and P6 as
ACCT_H, then P4, P5 and P6 terminals can select the transition
time.
[Multi-Accel/Decel Time Operation]
UP, DOWN:
By using the Up and Down function, the drive can
accelerate to a steady speed and decelerate down to a
desired speed by using only two input terminals.
Example:
If P1 is configured as ‘UP’ and P2 as ‘DOWN’, then Up/Down
operation can be achieved using P1 and P2 terminals.
