Switch-on delay after thread wiper (t7)
Switch-on delay without thread wiper (tFL)
It is possible to prevent unintentional foot lifting before thread trimming when changing from pedal position 0
(neutral) to position -2 by setting a switch-on delay (t2) using parameter
201 .
Holding power of the lifted foot:
The sewing foot is lifted by full power. Then the system switches automatically to partial power in order to
reduce the load for the control and the connected solenoid.
Set the duration of full power using parameter
203 and the partial holding power using parameter 204 .
