Digital and Analog Inputs and Outputs
- Disables Flying-Start: it is valid for P0202≠4. By applying +24 V to the digital input programmed for this
purpose, the Flying-Start function is disabled. By applying 0 V, the Flying-Start function is enabled again,
provided that P0320 be equal to 1 or 2. Refer to the section 12.7.
- Load User 1/2: this function allows the selection of the user memory 1 or 2, in a similar process than
P0204=7 or 8, with the difference that the user memory is loaded from a transition of the DIx programmed for
this function.
When the state of the DIx changes from low level to high level (transition from 0 V to 24 V), the user memory
1 is loaded, provided that the contents of the inverter actual parameters had been previously transferred to the
parameter memory 1 (P0204=10).
When the sate of the DIx changes from high level to low level (transition from 24 V to 0 V), the user memory 2
is loaded, provided that the contents of the inverter actual parameters had been previously transferred to the
parameter memory 2 (P0204=11).
- Load User 3: this function allows the selection of the user memory 3, in a similar process than P0204=9, with
the difference that the user memory is loaded from a transition of the DIx programmed for this function.
When the DIx state changes from low level to high level (transition from 0 V to 24 V), the user memory 3 is loaded,
provided that the contents of the inverter actual parameters had been previously transferred to the parameter
memory 3 (P0204=12).
NoteS!
Make sure that when using those functions the parameter sets (user memory 1, 2 or 3) be totally
compatible with the application (motors, Run/Stop commands, etc.).
It will not be possible to load the user memory with the inverter enabled.
If two or three parameter sets from different motors were saved in the user memories 1, 2 and/or
3, the correct current values must be adjusted at the parameters P0156, P0157 and P0158 for
each user memory.
- Programming Off: when this function is programmed and the digital input is with +24 V, parameter changes
will not be allowed, regardless of the values set at P0000 and P0200. When the DIx input is with 0 V, the
parameter changes will be conditioned to the P0000 and P0200 settings.
- DO2 and DO3 Timer: this function acts as a timer to activate and deactivate the relays 2 and 3 (DO2 and
DO3).
When the timer function for the relay 2 or 3 is programmed at any DIx, and a transition from 0 V to +24 V occurs,
the programmed relay will be activated with the delay set in P0283 (DO2) or P0285 (DO3). When a transition from
13
+24 V to 0 V occurs, the programmed relay will be deactivated with the delay adjusted in P0284 (DO2) or P0286
(DO3).
