A. Hi Drive special functions
A.1 Basic notions for using the Hi Drive loom
Il presente paragrafo si limita a riassumere le principali differenze tra un telaio Hi Drive ed un
telaio standard per quanto riguarda il suo utilizzo da parte del tessitore.
Per tutte le informazioni relative al collaudo, alle regolazioni, agli aggiornamenti software, ecc.,
fare riferimento ai paragrafi successivi.
Main differences:
Restart lights. The restart lamps flash whenever the loom is moving (apart from continuous
running); the flashing lamps mean that the loom is not safe; always wait for the lamps to go
out before attempting to carry out any work on the loom.
Oil pump. The oil pump stops if the loom is not restarted within a certain time after a loom stop.
If you try to start the loom up normally under such conditions, only the oil pump will start; only
after a further 7 seconds can you then start the loom up properly at continuous running (the
green and white lamps flash alternatively in the meantime).
Switching the loom on. If the green lamp flashes when you switch the loom on, you need to
press the slow motion button to start the loom reset. Once reset, the green lamp should stop
flashing: the loom is now ready to work. If the “reset failed code n” message appears, press
button “X” to see whether there is an emergency and then see para. D1 “Reset failed code x”
to discover the likely causes.
Hi Drive alarms. The list of Hi Drive alarms and explanations are at the end of this manual.
Most of the Hi Drive alarms can be reset by jogging the loom in slow motion, after which you
can continue to use the loom as normal. If this is not possible, switch the loom off and then
back on again; if the problem persists, technical assistance is required.
Special meanings of the lamps. As well as the standard loom functions, the warning lamps
also have the following extra meanings:
-Flashing green lamp on switching the loom on: request to reset the loom; to do this, press
the slow motion button
-Flashing orange lamp on start-up: waiting for Hi Drive to start up: wait for the lamp to stop
flashing
-steady orange lamp during manual use of the brake: brake released
-alternate flashing of the green and white lamps: this means that you need to wait a few
seconds before starting the loom up at continuous running; likely causes: a) the oil pump
has just started; b) too many start/stop commands one after the other
-flashing white lamp with long intervals: the loom is in pre-alarm mode (e.g. the motor
temperature is too high); read the message on the Console to find out what the problem is.
A.2 Software upgrades and general parameters
After each RTC software upgrade, you may need to configure a few settings:
-The following options need to be set in the Loom Setup page (the one that appears when you
first switch the loom on after changing the software release):
- Hi Drive = YES
- Loom width = specify the loom width

Hi Drive main page (without Memory Card)
A.3 Hi Drive main page
A “Hi Drive main page” is used on the Console; this opens when you press
The Hi Drive main page contains a series of data that can be set by the user. If a Memory Card
level 3 has been inserted, the relevant extra fields will appear in the page.

This page with the Memory Card inserted has that lets you access a second list of
buttons.
The brake status and coupling
status can be as follows:
The status of the coupling is “unknown” during the intermediate stages between its being en-
gaged and released. Moreover, if the coupling is used manually, the status continues to be given
as “unknown” after release and engaging (because the toothed wheels are tooth against tooth,
but not coupled): you need to jog the loom in slow motion to get the “coupled” status.
Data that can be set and displayed without Memory Card:
Engaged Unknown Released
Engaged Released
Brake statuses
Coupling statuses
Continuous loom running
, picks/min. The actual speed
appears at the side.
Oil pump shutdown time
(in minutes): how long after
the loom has stopped before the oil pump should
automatically stop; NB: the actual shutdown time may be
less than that set if the oil pump motor temperature is
particularly high.
Space covered with one slow motion command
(in
1/10 loom degrees).
Drive temperature (at rest here).
Motor temperature.
Oil pump motor temperature (at rest here).
Status of brake and coupling (see table above).
Main encoder value (degrees).
Auxiliary encoder value (degrees).

Extra buttons in the Hi Drive page with Memory Card
A.4 Manual use of the electromechanical brake
Press in the Hi Drive page. The orange lamp comes on, warning that the brake is re-
leased. Press the slow motion button to engage/release the brake.
Then press to return to the normal Hi Drive page.
If using the handwheel, the loom goes into emergency mode and the Hi Drive device switches off.
Disengage the handwheel and return to the normal Hi Drive page; now press the slow motion
button to switch the device back on again.
Note: with 7501.0120 SW release and higher, once the handwheel has been inserted, all
you need do is press the Slow Motion button to release/engage the brake, without having
to use the Console functions.
Go to next/previous list of buttons.
Show status of HDI board inputs and outputs. 2 of these
buttons are present (I/O1 and I/O2).
Access Setup page.
Access Test page, containing several settings that come in
handy when testing the loom.
Access the "Detect start pick-up" page.
