Each command may come from any of the drive digital input terminals (either standard or expanded), or can be a logical
combination of terminal inputs, obtained by using the drive internal programmable area
It is anyway possible to assign commands different from the default ones:
For example, if we want the Enable command to come from the digital input 3 of the drive (terminal 24 on the regulation
board), we have to set parameter I.000 Enable src to the value “[4] DI 3”.
Note:
If the source of a command is specified as an expanded DI, and the I/O expansion board is not mounted, the
command will always be inactive (FALSE).
A brief description of each command follows.
Enable src The Enable command must always be present, in order to activate the inverter output bridge. If the
Enable input is not present, or the Enable signal is removed at any time during the Lift sequence, the
output stage of the drive is disabled, and the Run contactor is open, regardless of the status of all the
other inputs.
Run Fwd src (Upward command)
Closing the input 23, the upward Lift sequence is started (see Figure 7.1).
Run Rev src (Downward command)
Closing the input 24, the downward Lift sequence is started (see Figure 7.1).
Note:
The direction of the motion can also be reversed by setting a negative frequency reference. With a negative
frequency reference, the Run Fwd src command will cause a downward motion, while a Run Rev src
command will cause the cabin to move upward.
Note:
The lifting sequence will not start if both Run Fwd src and Run Rev src commands are activated at the
same time.
Freq Sel 1 ... 4 src (Selection of the speed reference)
The binary code defined by the status of these signals selects the frequency reference (speed) for
the ramp generator (see Fig.7.2), according to the following table:

Table 7.2 – Multi-frequencies selection
Note:
The last multi-frequency has also a special meaning when using the backup power supply. If the drive is
being fed by the backup power supply, the frequency reference is clamped to the value defined by the
parameter F. 115 .
If the backup power supply is not used, F.115 can be used as one of the multi-frequencies and is selected by
setting to TRUE all the selectors (Freq Sel 1 to Freq Sel 4).
