The influence of the digital input terminals upon control of the frequency converter can be programmed in par. O-50 Coasting Select to par. O-56 Preset Reference
Select
. Please note the par. O-01 Control Site overrules the settings in par. O-50 Coasting Select to par. O-56 Preset Reference Select, and Terminal 37 Coasting

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 network only, network AND Digital Input, or Ether Network OR Digital input terminal.

In order to control the frequency converter via PROFIBUS, 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 [0] or [2].

More detailed information and examples of logical relationship options are provided in the Troubleshooting chapter.
