8.9 Positions
Function with or without control panel Parameter
Selection according to position sensor (PGm) 270
Number of angular degrees from the sensor position to position 2 (PGr) 271
Transmission ratio between motor shaft and machine shaft (trr) 272
After setting parameter 270 at “1, 2, 3 or 4“, an angular degree must be selected using parameter 271, which determines the
stop in position 2 or 1 after the sensor position. The angles are preset in modes 31 and 32, parameter 270 = 6. The
transmission ratio must already have been input using parameter 272.
Connection of a sensor (N.O. function) e. g. light barrier to socket B18/7.
The following settings are possible using parameter 270:
270 = 0 - The positions can be generated with the help of the transmitter incorporated in the motor and can be
set by means of parameter 171.
270 = 1 - Setting the sensor to position 2.
- Position 1 is set according to the angular degree setting by means of parameter 271.
- Start measuring from leading edge position 2.
- 0V at input B18/7 (inside of the window)
- +5V at input B18/7 (outside of the window)
270 = 2 - Setting the sensor to position 2.
- Position 1 is set according to the angular degree setting by means of parameter 271.
- Start measuring from trailing edge position 2.
- Input and output level as with setting “1“
270 = 3 - Setting the sensor to position 1.
- Position 2 is set according to the angular degree setting by means of parameter 271.
- Start measuring from leading edge position 1.
- Input and output level as with setting “1“
270 = 4 - Setting the sensor to position 1.
- Position 2 is set according to the angular degree setting by means of parameter 271.
- Start measuring from trailing edge position 1.
- Input and output level as with setting “1“
270 = 5 - There is no position sensor. The drive stops unpositioned. The thread trimmer is suppressed.
270 = 6 - The positions are determined by preset values. The reference position must be correctly set for this
purpose. In machines with position sensors incorporated in the handwheel the reference position is
determined by mechanical adjustment. In all other cases the reference position must be set (see
chapter “Setting the Reference Position”) in order for the angles preset by machine select for
positions 1 and 2 to be correct. If necessary, the preset values can be adapted as described in
chapters “Setting the Positions”.
