4 Drive Special Functions
4.1.1 Special Functions
In addition to the control strategies described above, the drive provides additional control flexibility to allow it to integrate into special control system requirements.
The following are just a few examples.
4.1.2 Analog Input Monitoring
Points 87 and 88 can be used to monitor the value of the analog control signals applied to terminals 53 and 54. These points are active even when NO FUNCTION
is programmed for the analog input of the drive. As a result, it is possible to use the frequency converter analog inputs as analog input for the FLN.
4.1.3 Drive Relay Control
While relay 1 and 2 in the Drive usually provide drive status indications, these indications are generally not needed, when the drive is connected to a FLN network.
In some applications, it can be useful to have the FLN control these relays. For example, by controlling one of the relays, the FLN could select the active pump in
a pump sequencing system. For the FLN to control a drive relay, the appropriate Drive parameter (
E-24.0 or E-24.1) must be set to [Bus Control]. Setting relay 1
or 2 to [On] will then activate the corresponding relay.
