5.2.4 Real Time Clock Variable
The drive has a built-in real-time clock. The standard real-time clock has no battery back-up function, which will lead to a time stop if the Drive is unpowered.
Some BACnet Master's can be programmed to send out the date and time as a Broadcast Telegram on a regular basis. The BACnet will update the real-time clock
of the Drive if it receives this type of telegram: “Telegram”.
5.3 Drive Feedback to Network
The BACnet option provides several output variables (nvo’s) to the network, containing important drive -, motor- and I/O feedback data. The BACnet option transmits
bound network variables only and sends feedback data when there is a change in value.
Influence of the digital input terminals upon the Drive Control Mode, par. O-50 Coasting Select to par. O-56 Preset Reference Select
The influence of the digital input terminals upon control of the drive can be programmed in par. O-50 Coasting Select to par. O-56 Preset Reference Select.
NB!
par. O-01 Control Site overrules the settings in parameters O-50 to O-56.
Each of the digital input signals can be programmed to logic AND, logic OR, or to have no relation to the corresponding bit in the control word. In this way a specific
control command i.e. stop / coast, can be initiated by the network only, network AND Digital Input, or Ether Network OR Digital input terminal.
In order to control the drive via BACnet, par. O-50 Coasting Select must be set to either Bus [1], or to Logic AND [2] and par. O-01 Control Site
must be set to Digital and ctrl. word [0] or Controlword only [2].
More detailed information and examples of logical relationship options are provided in the Troubleshooting chapter.
