Efka dc 1500 - Intermediate Backtack; Stitch Regulator Suppression;Recall; Holding Power of the Stitch Regulator Solenoid

EFKA FP220A5911
55
The parameters of the end backtack speed and the backtack stitches forward / backward are identical with the standard end
backtack.
Difference from the standard end backtack:
! The drive stops for stitch regulator switching
! The stop time can be set
When using the V820 control panel, direct access by means of the function key (9 key) is possible!

Ornamental backtack On/Off (-F-) 008 = 2
11.7 Intermediate Backtack
Upon pressing an external key according to the preselection of parameters 240...249, the backtack solenoid can be switched
on anywhere in the seam and at standstill.
See List of Parameters chapter Connection Diagram!
11.8 Stitch Regulator Suppression/Recall
Effective in standard and ornamental backtack
The next backtack and/or stitch condensing operation can be suppressed or recalled once by pressing an external key
according to the preselection of parameters 240...249.

11.9 Holding Power of the Stitch Regulator Solenoid
Function with or without control panel Parameter
Time of full power (t10) 212
Holding power of the stitch regulator solenoid (t11) 213
Upper limit stitch regulator ON period (EV-) 255
The stitch regulator solenoid is engaged 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 by means of parameter 203 and
the partial holding power by means of parameter 204.
CAUTION!
If the holding power is set too high, the solenoid and the control may be permanently
damaged. Please observe the permissible duty ratio (ED) of the solenoid and set the
appropriate value according to the table below.
