■ Function: Fixed Speed Auto (Setting: 86)

A digital input can be configured to enable the Fixed Speed Auto (H1-0x = 86) when operating in the Auto Mode. A contact closure into

the multi-function input will enable the Fixed Speed Auto function.

The Fixed Speed Auto will cause the drive to run at the iQpump drive Multi / Maximum Level (P3-02) and disable the PI Control, Sleep

Mode and Lead / Lag operation.

When the digital input is open, the Fixed Speed Auto is disabled.

Note: Pre-charge and Thrust Bearing functions have a higher priority than Fixed Speed Auto.
