4 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
If necessary, the correct adjustment of the direction of motor rotation using parameter 161
Verify using parameter 280 that the appropriate series is connected
The setting of the reference position using parameter 170
The setting of the positions using parameter 171
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
Start sewing in order to save the set values
If the power is turned off before sewing has been started, the settings get lost!
5 Setting the Basic Functions
5.1 Direction of Motor Rotation
Functions Parameter
Direction of motor rotation (drE) 161
Parameter 161 = 0 Clockwise motor rotation
Parameter 161 = 1 Counterclockwise motor rotation (look at the motor shaft)
5.2 Selection of the Machine Series
Functions Parameter
Display of the machine series (SEL) 280
The various machine models are specified by resistors. The following resistance values (tolerance ± 1%) are provided:
Machine model = 271, N291, 8967 = 100Ω
204, 205, 221, 266, 366 = 220Ω
069, 267, 268, 269, 4180, 4280 = 680Ω
381, 382, 467, 767, 768 = 1000Ω
The special functional sequences for this machine type and the various preset values are activated depending on the resistor
identified. The machine select is displayed using parameter 280. The resistance value is displayed in Ohm directly on the
control panel.
ATTENTION
If the motor is mounted differently, e. g. at a different angle or with gear, make sure
that the value set using parameter 161 corresponds to the direction of rotation.
