Treadle (speed control unit) Example: Displays the fourth speed stage
Fig. 10.4
Testing treadle stages (speed control unit stages):
By pressing the treadle forwards (on the speed control unit), the active treadle stages are displayed, treadle
stages from -2, -1 to 0, +1 and from 1D to 24D are possible,
depending on the setting for parameter <608> to 0 or 1 means 12 treadle stages,
to 2 or 3 means 24 treadle stages
Depending on how far forwards the treadle is pressed, treadle stages 1D to 12D and to 24D are selected
Treadle stage 0: Treadle at rest
Treadle stage +1: 1. Treadle stage, lower presser foot
Treadle stage 1D: Treadle at first speed stage
Treadle stage 2D: Treadle at second speed stage
Treadle stage 3D: Treadle at third speed stage
Treadle stage 4D: Treadle at fourth speed stage (Fig. 10.4)
to: etc.
Treadle stage 12D: Treadle at twelfth speed stage
max. speed (if parameter <608> = 0 or 1).
or
Treadle stage 24D: Treadle at twenty-fourth speed stage
max. speed (if parameter <608> = 2 or 3).
By pressing the treadle backwards (on the speed control unit), the active treadle stage is shown on the display!
Treadle stage -1D: Treadle in first backwards treadle stage (e.g. lift presser foot)
Treadle stage -2D: Treadle in second backwards treadle stage (e.g. for thread trimming)
The treadle test mode is selected using keys A+ / A- (Fig. 10.4)
