Page 18: Programming Interface
5.1 Configuring the encoder using the software tool SFEM1 & 2 programmable incremental draw-wire encoder is provided with a software expressly developed and released by Lika Electronic in order to easily programme and configure the device. It allows the operator to set the working parameters of the device and monitor whether the device is running properly. -
Page 19: Starting The Program
SFEM1 & 2 programmable draw-wire encoder WARNING Please always close the programming interface before disconnecting the encoder ! 5.2 Starting the program To launch the program just double-click the KIT IP_IQ58_vx.x.EXE executable file. The main page of the configuration interface will appear on the screen. A further page is dedicated to the diagnostic information;... -

Page 21: Setting The Parameters
SFEM1 & 2 programmable draw-wire encoder 5.4 Setting the parameters WARNING To save the data on the EEPROM permanently, after having entered the new value you must press the ENTER button in the keyboard. The parameter is saved instantly. Internal pos. register It is used to show the value in the internal position register, that is: the current position of the encoder. - Page 22 SFEM1 & 2 programmable draw-wire encoder To convert the position value into millimetres (mm) or micrometres (µm) you have to multiply the number of information by the linear resolution of the encoder expressed in millimetres or micrometres. To know the linear resolution of the encoder please consider that the stroke per turn is 200 mm.

Page 23: Counting Direction
SFEM1 & 2 programmable draw-wire encoder Counting direction By default the counting direction is positive when pulling the wire out (the A channel leads the B channel, see the Figure on page 24). This parameter allows to reverse the counting direction, i.e to have a count up when the wire rewinds Counting direction = CCW to have the increasing count around the drum. -
Page 24: Index Position
SFEM1 & 2 programmable draw-wire encoder Index position The encoder provides the zero signal (Index pulse) once every 200 mm / 7.874” of linear displacement (that is once per revolution of the encoder shaft) as relative positioning reference (home position, see the Figure above). In this way a unique position can be identified at a well-known point in the 200 mm / 7.874”... -
Page 25: Max Rpm
SFEM1 & 2 programmable draw-wire encoder Max rpm It allows to optimize the encoder performance (by keeping the most efficient ratio between the encoder rotational speed and the signal edge distance), depending on the maximum speed the application is able to reach. Since the maximum speed and the resolution are strictly correlated, some options may be disabled or limited as you enter increasing resolutions. -
