Checking Needle Positions Np1/Np2; Checking The Maximum Speed; Sewing Head Synchronisation - Pfaff PicoDrive P40PD Instruction Manual

10.3

Checking needle positions NP1/NP2

NP1 - needle down (<702>)
NP2 - thread lever up (<703>)
a) Switch on programming level "b" (mechanic level) (see Chp. 9.2 Programming level "b")
b) Call up parameter <702>
c) Press treadle forwards
Response: Machine starts up and positions according to <702>
d) Is the needle position correct?
If yes, then continue with g)
If no, then correct position by :
Turning the handwheel or
using keys D+ or D− on the PicoTop
e) Press treadle forwards
Response: Machine makes one revolution and positions to the same position.
f) Position can be corrected again.
g) The last value set <702> is saved by calling up a new parameter number, e.g. <703>.
h) Proceed in the same way with parameter <703> as described above for parameter <702>.
i) Switch off programming level "b". (See Chp. 9.2 Programming level "b")
10.4

Checking the maximum speed

a) Switch on programming level B (see Chapter 9.2 Programming level "b")
b) Call up parameter number <607>
c) Check parameter value <607> and if necessary correct using
keys D+ and D− on the PicoTop
d) Switch off programming level "b" (see Chapter 9.2 Programming level "b")
10.5

Sewing head synchronisation

If sensors for the up and down position are recognised (in connection with synchronisers PD4, PD5),
parameters <700>, <702> and <703> are not displayed on the control panel.
The up and down positions must then be adjusted using magnets in the handwheel.
