3 Putting into Service
Before putting the control into service, the following must be ensured, checked and/or adjusted:
 The correct installation of the drive, position transmitter and accompanying devices, if necessary
 The correct selection of the trimming operation using parameter 290
 If necessary, the correct adjustment of the direction of motor rotation using parameter 161
 The correct selection of the functions of keys (inputs) using parameters 240...249
 The setting of the transmission ratio between motor shaft and machine shaft using parameter 272
 The setting of the type of position sensor using parameter 270
 If necessary, the setting of the number of angular degrees after the sensor position using parameter 271
 If necessary, the setting of the positions using parameter 171 (possible with all settings of parameter 270)
 The correct positioning speed using parameter 110
 The correct maximum speed compatible with the sewing machine using parameter 111
 The setting of the remaining relevant parameters
 Begin sewing in order to save the set values
4 Top part detection
In machines equipped with a top part detection module (OTE module), all parameters needed for the sewing
process are set according to the values stored in the module.
Whether an OTE module is present and, if so, which module, is tested each time the power is turned on.
Depending on the result of the test, different messages appear on the display of the control panel, and different
operations are possible and/or required:

Program ID of control
older than that of the
OTE module
oLd ProgId (2 sec.)
otE updAtE
0 = do not overwrite OTE
1 = overwrite OTE with the parameters
read out of the control.
The possible options (e.g. 0 or 1) are selected by pressing the + / - keys on the control panel. Confirmation with
the P or E key.
*1)
To determine the transmission ratio, the pedal must be pushed fully forwards. The drive runs at a reduced
speed until the transmission ratio has been determined, then releases the pedal controlled speed. The
display Pulley goes out.
It is also possible to format a top part detection module using parameter 850.
