Teach Process For The Gear Ratio - Pfaff PicoDrive P40PD Instruction Manual

10.2

Teach process for the gear ratio

This is required if the motor drives the machine via a V belt (Parameter <802> = 1),
or when there is an increase or reduction in ratio of motor to machine
(unequal 1:1).
Hardware prerequisite: Synchroniser PD3 or another sensor, that
delivers precisely one impulse per revolution. After switching on for the first time or after a master reset,
the control unit recognises the connected synchroniser.
"PULLEY" (Fig. 10.1) is shown in the upper line of the display
The teach phase is introduced by pressing the treadle forwards.
The drive system runs at low speed until the teach phase is concluded.
This process cannot be interrupted!
"PULLEY" is deleted from the display.
Error message:
If no signal is recognised from an external sensor after sewing start and a wait period,
"ERROR 74" is displayed; the drive system stops without position.
