◆ C1-11 Accel / Decel Switch Frequency

Setting Range: 0.0 ~ 200.0 Hz

Factory Default: 0.0 Hz

The iQpump 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 iQpump 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.
