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!
