The functioning of the speed limitation when using an external potentiometer can be selected using parameter
126.
The desired limitation speed is set using a potentiometer connected to socket ST2/2-4. The maximum/minimum
value of speed limitation is set using parameters 124/125.
124
Maximum value for speed limitation with external potentiometer
125
Minimum value for speed limitation with external potentiometer
126 = 0
Function "external potentiometer" Off.
126 = 1
The external potentiometer is active whenever the pedal is pressed forward.. The drive always
runs with the set speed limitation.
126 = 2
The external potentiometer is active only if an input is set at "25" by means of parameters
240...249. If the selected input is enabled and the pedal pressed forward, the drive runs at limited
speed. The speed limitation can be enabled and disabled anywhere in the seam using the key.
126 = 3
Speed depending on high lift by means of potentiometer e. g. Juki (LU-2210/2260).
126 = 4
Speed depending on high lift by means of potentiometer e. g. Dürkopp Adler (767).

Key 8
Parameters 300-309, 330, 331 for A1 and 310-319, 335, 336 for A2 determine when and how long the signals
are enabled or disabled, or other conditions take effect.
When a V820/V850 control panel is used, signals A1/A2 can be assigned to a seam using key 8 (slide-in strips
6, 8, 9 and 10).
Using parameter 300/310 it is possible to set which output (M1-M11 or VR) can be switched by A1/A2.
Using parameter 301/311 it is possible to select if signal A1/A2 is effective until the seam end, stop at the seam
end, over time or during stitch counting.
301/311 0
to end of seam (parameter 320)
1
Over time (parameter 304/305/314/315)
2
Until stop at the seam end
3
During stitch counting (parameter 308/309/318/319)
4
Puller function (parameter 309/319)
Using parameter 302/312 it is possible to select if the signal A1/A2 shall be effective at the start of the seam,
after light barrier sensing or at the seam end.
302/312 0
Signal at the beginning of the seam
1
Signal after light barrier sensing
2
Start of the signal when the drive stops at the seam end
3
Signal from light barrier covered at the start of the seam
4
Signal switchable only manually
Using parameter 303/313 it is possible to select if the signals shall be activated with or without delay.
302/313 0
Without delay time
1
After a delay time (parameter 308/318)
2
After a stitch count (parameter 309/319)
The delay time can be selected using parameter 304/314.
The ON period can be selected using parameter 305/315.
