This menu contains all the parameters that have a direct effect on
driving of the pump.
HIGH SPEED ADJ
: Sets the rotational speed of the pump when the
low-speed function is not active, expressed either in Hz or KRPM.
LOW SPEED ADJ:
Sets the rotational speed of the pump when the
low-speed function is active, expressed either in Hz or in KRPM.
SOFT START:
enables (YES) or disables (NO) the soft start function.
This parameter is visible only if the controller is configured in
FRONT mode.
EXTERNAL FAN:
it’s possible to operate the external cooling fan
selecting between following options:
ALWAYS ON: the cooling fan is always ON
AUTOMATIC: The vent valve behavior is managed by
the controller (see Drive the External Fan chapter)
SERIAL: the cooling fan is controlled directly via the
serial port.
VENT VALVE MODE:
it’s possible to operate the optional vent valve
selecting between following mode of operation:
AUTO TIME: the valve is controlled by the controller
SERIAL: the valve is controlled by the serial port.
AUTO PUMP SPEED: the valve is controlled by the
controller its king into account the pump’s
deceleration.
VENT VALVE DELAY
: Sets the delay, expressed in seconds, between
stopping of the pump and opening of the vent valve.
VENT OPEN TIME:
sets the time, expressed in seconds, for the vent
vale to stay in open condition. Enter 0 if the valve has to stay open
until the next start.
LOAD GAS TYPE:
selects the type of gas used in the process.
Therefore, the controller limits the power supplied to the pump
according to this setting.

WATER COOLING:
indicates whether
the pump is cooled with water or not.
The controller limits the power supplied to the pump according to this setting.
TMP
r
otor stopping:
to enable set YES, to disable set NO.
STOP SPEED READING:
enables (YES) or disables (NO) the reading
function of the pump rotational frequency during braking, after stop
command.
