Switching Accel/Decel Times With Digital Input Terminals; Automatically Switching Acceleration/Deceleration Times; Accel/Decel Time Switching Frequency - YASKAWA V1000 Series Installation & Start-Up Manual

Setting
0 Time is set in units of 0.01 s, making the setting range 0.00 to 600.00 seconds.
1 Time is set in units of 0.1 s, making the setting range 0.0 to 6000.0 seconds.

Switching Accel/Decel Times with Digital Input Terminals

■
Up to four different acceleration / deceleration times can be selected using any two digital
input terminals S1 through S7.
Program two parameters H1-01 through H1-07 to "07" (Accel/Decel Time 1) and "1A"
(Accel/Decel Time 2). The combination of these two inputs activates the acceleration/
deceleration times as shown below. As the contacts of the terminals open and close, the
following acceleration and deceleration time combinations are possible:
Accel/Decel Time 1
H1- = 7
Open (not selected)
Closed
Open (not selected)
Closed

Automatically Switching Acceleration/Deceleration Times

■
The drive can automatically switch between acceleration and deceleration times.
When the output frequency reaches the value set to C1-11, the drive will switch acceleration
and deceleration times as shown in the figure below. Setting C1-11 to 0.0 Hz disables this
function.
