7. Description of the PicoDrive drive system
The PicoDrive drive system is an electronically commutated, brushless DC motor.
The drive system comprises the following main assemblies:

7.1 Motor QE3760/QE5540
Themotor is a synchronous motor. Ithas a permanent-magnet rotor, an opto-electronic commutation
transmitter (rotor position sensor) that is mounted on the fan side, and a stator with three-phase
winding.
The rated output of the motor (shaft output) is 375W (QE3760) / 550W (QE5540) in S5 mode. The
rated speed of the motor is 6000 rpm (QE3760) / 3700 rpm (QE5540); the maximum speed is 9000
rpm(QE3760)/4000 rpm (QE5540).
Themotor has two connection cables
a) four-conductorwith four-contactAMPspecial plug (X1) for connecting the statorwindings to the
control system
b) six-conductorshieldedwithnine-contactD-subconnector(X2)forconnectingthecommutation
transmitter to the control system.

The control system casing is suspended from below and screwed to the table top with four screws
whichareincludedwith delivery.
The mains connection is single-phase via the three-conductor cable exiting from the back by means of
a locally used plug with earthing contact.
The control unit has peripheral function controls

7.3 Speed control unit SCU2
The SCU2 is secured beneath the machine table using the bracket included and is mechanically
connected to the machine treadle by means of a pitman rod.
The SCU2 is connected electrically via the nine-connector coupling to the X3 connector on the back of the
control unit.
TheSCU2isananalogue,mechanical-electricalconverterthatconvertsthetreadlepathintoananalogue
control voltage. This analogue output voltage of the SCU2 is digitalised in the control unit so that the
treadle path is subdivided into 26 stages (-2, -1, 0, 1D to 22D).

7.4 External PicoTop control panel
The PicoTop control panel(Fig. 7.14) has the following components
-a single line display with an 8-digit LCD matrix
-4setting ranges: A+ / A-, B+ / B-, C+ / C-, D+ / D- (when TE on)
-the T11 key (PM) for choosing the mode
"manualsewing"or "programmedsewing".
-the T10 key (TE) for switching on the "Alter set values" mode
such as backtack stitches, parameters values.
-the T9 key (paging) to change the function type
such as backtack stitches, parameters values and speed.
-8keys(T1...T8) for machine functions (when TE off)
Function of keys T1 … T8 for machine functions
-T1 frontbacktack (on / off)
-T2 end backtack (on / off)
-T3 needle position at sewing stop (up / down)
-T4 threadtrimming(on / off)
-T5 presser foot position at sewing stop (up / down)
-T6 presserfootposition after end of seam section (up / down)
-T7 sewingwithlight barrier (on / off)
-T8 function key F1
The keys T1…T8, T10 and T11each have a signal light (LED).
The T9 key has no signal light (LED).
Each LED gives an optical response regarding the switch status of the function allocated to the respective key.
If the function is switched on,If the function is switched off,
the LED lights up! thentheLEDis off!
