C1-11 Accel/Decel Switch Frequency
Setting Range:
0.0 to 200.0 Hz
Factory Default: 0.0 Hz
The Drive can be programmed to automatically switch between the two sets of Accel/Decel parameters on the fly. No digital
input is required. If parameter C1-11 is set to a frequency other than zero, the Drive will use Acceleration 1 and Deceleration
1 whenever the output frequency is equal to or above the value of C1-11 and use Acceleration 2 and Deceleration 2 whenever
the output frequency is below the value of C1-11.
A multi-function input programmed as "Multi-Acc/Dec 1" will have priority over C1-11. For example, if the output frequency
is greater than the value of C1-11 but a digital input configured as "Multi-Acc/Dec 1" is closed then Acceleration 2 and
Deceleration2 are active.
