This is not a safety function. The line voltage must still be switched off during maintenance and
repair work.

281
282
283
Parameter 281 is used to preselect how the drive is turned back on after the machine run block is lifted.
281 = 0
Back on immediately from any pedal position
281 = 1
Back on only when pedal in 0 position
Parameter 282 is used to determine the effect of the run block switch.
282 = 0
N.O. (switch closed = machine run block on)
282 = 1
N.C. (switch open = machine run block on)
The machine run block is toggled in its function with parameter 283.
283 = 0
Machine run block turned off
283 = 1
Machine run block function 1 (safety function) fastest possible stop without positioning
283 = 2
Machine run block function 2 (control function) with positioning to the currently configured position
The machine run block function is enabled by connecting a switch to socket A/11-33. When using a control
panel, an acoustic signal can be switched on and/or off by means of parameter 127.

In all variants of the machine run block function, sewing foot lifting is possible. Needle up/down and/or its
variants are not possible, however.
6.14.1 Run block (block 1 and 2)
If the machine run block input is active during machine standstill, the drive is stopped despite actuation of the
pedal. Starting is only possible after the input is deactivated.
6.14.2 Machine run block function 1 (safety function) parameter 283 = 1
In start backtack:
 Fastest possible stop without positioning. The start backtack is interrupted.
 Trimming is not possible.
 After lifting of the machine run block, pedal > 1 continues the start backtack and the seam, or pedal –2
starts thread trimming.
