7.4 Speed specification
The pump can be actuated by analog or digital means. The
speed setpoint of the pump can be carried out by one of three
options:
à
Analog control voltage,
à
PWM setpoint setting,
à
Digital setpoint setting.
A standard-analog configured pump can be switched to digital
mode at any time with the start command "dU" via the UART
interface. The pump then remains in this mode until it is ac-
tively disconnected from the supply voltage.
