Acceleration and Deceleration Characteristics

Switching Acceleration and Deceleration Time Using Multi-Function Input Terminal
Commands
Using the Inverter, you can set four acceleration times and four deceleration times. When the multi-function
input terminals (H1-
) are set to 7 (acceleration/deceleration time selection 1) and 1A (acceleration/decel-
eration time selection 2), you can switch the acceleration/deceleration time even during operation by combin-
ing the on/off status of the terminals.
The following table shows the acceleration/deceleration time switching combinations.
Switching Acceleration and Deceleration Time Automatically
Use this setting when you want to switch acceleration/deceleration time automatically using the set frequency.
When the output frequency reaches the set value in C1-11, the Inverter switches the acceleration/deceleration
time automatically as shown in the following diagram.
Set C1-11 to a value other than 0.0 Hz. If C1-11 is set to 0.0 Hz, the function will be disabled.

S-curve
characteristic time
at acceleration start
All sections of the S-curve characteris-
tic time are set in seconds units.
When the S-curve characteristic time
is set, the accel/decel times will
increase by only half of the S-curve
characteristic times at start and end.
