6.17.13 Backtack suppression / backtack call (Function module A)
Function with or without control panel
Parameter
Backtack suppression / recall
(FMA)
250 = 15
When the external key is pressed, the next backtack process can be suppressed or called one time.
Confirmation of the key press is carried out with the LED.
See also section Backtack suppression/backtack call.
6.17.14 Single stitch backwards with stitch length switch(Function module A)
Function with or without control panel
Parameter
Single stitch backwards with stitch length switch
(FMA)
250 = 16
With a key pressed after sewing starts, output A, LED A, and the backtack solenoid are turned on in the
intermediate stop. The drive starts and is positioned in needle position 1.
6.17.15 Speed limitation DB2000 (Function module A)
Function with or without control panel
Parameter
Speed limitation DB2000
(FMA)
250 = 17
Once input A is confirmed, the drive runs at a limited speed n10 (parameter 117)
6.18 Function modules for outputs B and C
The functions for modules A/B/C are identical. The functions of the mode selected with parameter 250 (A), 255
(B), and/or 275 (C) are equivalent to those described in module A.
If the same mode is selected in module B and/or C as in module A, the settings in module A take priority.
The assignment of the inputs and outputs used to the modules are shown in tabular form in section "Function
modules for outputs A / B / C".

6.19 Speed limitation
6.19.1 Speed limitation DB2000/DB3000
Function with or without control panel
Parameter
High lift walking speed (DB2000)
Speed limitation (DB3000)
(n10)
(n11)
117
289
The control inputs on A/9 (DB2000) and A/10 (DB3000) limit speed to 2000 RPM and 3000 RPM respectively.
The limited speeds can be changed with parameters 117 and 289. When the states of the control inputs
change, the corresponding speed limit takes effect or is canceled with a delay of about 50 ms.
NOTE
When simultaneously using different speed limits, the maximum speed is limited the lower value.
