Data examples
Set min/max speeds
The min/max speed parameters are used to set the minimum and maximum speed from the PROFIBUS
interface. The values are only used if the matching bit in the Control Word is enabled and they are not
zero. All values are 16 bit unsigned in 1/10th of RPM of the head speed.
Fail-safe
The fail-safe user parameter is used to set the correct course of action to take in the event of a PROFIBUS
communications failure. The fail-safe byte is configured as shown in the following table. If no bits are set
or an invalid bit pattern is set the default fail safe behaviour shall be to stop the pump.
Bit Description
0x00 No fail safe action
0x01 Last demanded speed
0x02 Fail-safe speed
The fail-safe speed parameter is used to set the speed at which the pump should be driven is a PROFIBUS
communications error occurs and if bit 1 in the fail safe user parameter is set.
