Checking The Direction Of Rotation And Reference Position Of The Needle Bar (Needle Position Np0) - Pfaff PicoDrive P40PD Instruction Manual

10. Commissioning
If the PicoDrive has been stored at temperatures <+5°C, it must be brought up to
an operating temperature between +5°C to +45°C before commissioning.
There must be absolutely no moisture!
Before you can work with the machine, carry out the following:
a) Check the direction of rotation and the reference position of the needle bar
b) Check the needle positions
c) Check the maximum speed
d) If necessary, carry out the gear ratio teach process (see Chp.10.2).
10.1 Checking the direction of rotation and the reference position of
the needle bar (needle position NP0)
a) Switch on programming level "b" (mechanic level) (see Chp. 9.2 Programming level "b")
b) Call up parameter 700
c) Press treadle forwards
Response: Machine starts up and positions to a non-specified position
d) Is the direction of rotation correct?
If yes, carry out the zero point adjustment, continue with e)
If no, then set parameter number 800 and switch on value <800> (*0 ®
or *1 ®
*0), then continue with b)
e) Turn the handwheel on the machine in the direction of movement until the
needle point (approaching from above) reaches the level of the needle plate (= reference
position).
f) Press treadle forwards
Response: Machine makes one revolution and positions to the same position as was previously
set by hand.
g) Set new parameter number or switch off programming level "b"; parameter value <700> is saved,
the zero point adjustment is concluded.
Correct assembly of the timing belt (see Chp. 6.2 in Section 1) will mean that the zero position
(reference position) of the machine shaft will match the zero position of the motor's incremental
encoder.
This ensures optimum running behaviour of the motor!
