AGL50-EV 25
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 16 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 specied 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 14, the upward Lift sequence is started (see Figure 7.1).
Run Rev src (Downward command)
Closing the input 16, 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 com-
mand 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 dened by the status of these signals selects the frequency reference (speed) for
the ramp generator (see Fig.7.2), according to the following table:
Freq Sel 4 Freq Sel 3 Freq Sel 2 Freq Sel 1 Code Active frequency reference
Terminal XX Terminal 22 Terminal 20 Terminal 18
0 0 0 0 0 S.200 Rif frequenza 0
0 0 0 1 1 S.201 Rif frequenza 1
0 0 1 0 2 S.202 Rif frequenza 2
0 0 1 1 3 S.203 Rif frequenza 3
0 1 0 0 4 S.204 Rif frequenza 4

1 1 1 1 15 F.115 Rif frequenza 15
(Emergency run freq)
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 dened by the para-
meter 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).
