PumpDrive 2
NOTE
If the field bus is only used for monitoring purposes, the Control Point parameter
3-6-2 is set to Local.
NOTE
The frequency inverter is reset when a field bus module is replaced or retrofitted.
Menu 3-12 for setting the parameters of the field bus module is then enabled.

3-6-2 Control Point
Toggling the control point from Local to Field

3-12-2-5 Cycle Time, Setpoint/Control Value
Time delay before the message (warning or
alert) is triggered. In a redundant system, only
a warning is output as the auxiliary master can
assume the function. Only if the setpoint/
control value also fails at the auxiliary master is
the alert output, which then triggers the
specified response to setpoint/control value
failure.

3-12-2-6 Cycle Time, Actual Value
Time delay before the message (warning or
alert) is triggered. In a redundant system, only
a warning is output as the auxiliary master can
assume the function. Only if the actual value
also fails at the auxiliary master is the alert
output, which then triggers the specified
response to actual value failure.
