Unwanted foot lifting before the thread is cut when transferring to pedal 0 position after stage 2 can be prevented
by setting a power on time lag with parameter t 03 11.
Important
The max. time that the sewing foot can be permanently raised is restricted by parameter t 03 52. After the time
has elapsed it is lowered automatically and can only be raised again by pressing the pedal back (-1). From this
time the restriction time is effective again. Sewing foot monitoring is switched off with parameter t 03 52 = 0.
Holding force of the raised foot
The sewing foot is raised by full activation. Then it switches automatically to partial activation to reduce the load
on the control unit and the connected magnets.
The full activation period is set with parameter t 03 51 and the holding force during partial activation with
