Page 277 Appendix A.5 Interconnecting signals in the inverter Binectors and connectors Connectors and binectors are used to exchange signals between the individual blocks: ● Connectors are used to interconnect "analog" signals. (e.g. MOP output speed) ● Binectors are used to interconnect "digital" signals. (e.g. 'Enable MOP up' command) Figure A-5 Symbols for binector and connector inputs and outputs Binector/connector outputs (CO/BO) are parameters that combine more than one binector...

Appendix A.5 Interconnecting signals in the inverter A.5.2 Example Moving a basic control logic into the inverter A conveyor system is to be configured in such a way that it can only start when two signals are present simultaneously. These could be the following signals, for example: ●...
Page 279 Appendix A.5 Interconnecting signals in the inverter Explanation of the example using the ON/OFF1 command Parameter p0840[0] is the input of the "ON/OFF1" block of the inverter. Parameter r20031 is the output of the AND block. To interconnect ON/OFF1 with the output of the AND block, set p0840 = 20031.

Appendix A.6 Application Examples Application Examples A.6.1 Setting an absolute encoder Encoder data In the following example, the inverter must evaluate an SSI encoder. The encoder data sheet also includes the following encoder data: Table A- 11 Excerpt from the data sheet of the absolute encoder Feature Value Configuring an...
Page 281 Appendix A.6 Application Examples Configuring an encoder When configuring the encoder, you must select an encoder type that has the best possible fit to the real encoder. Precondition You have started to configure the drive. Procedure Proceed as follows to set an absolute encoder in STARTER: 1.
Page 282 Appendix A.6 Application Examples Adapting the encoder data After the configuration you may now adapt the encoder data. Preconditions ● You have now configured an absolute encoder. ● You have completely configured the drive. Procedure Proceed as follows to adapt the encoder data: 1.
Page 283 Appendix A.6 Application Examples 3. … 10. In the "Encoder data" screen form, adapt the settings corresponding to the data sheet of your encoder. The "Details" tab is used for application-specific settings, e.g. to invert the encoder signal. The fine resolution can be separately set for the process data Gx_XIST1 and Gx_XIST2. 2 bit fine resolution is practical for square wave encoders.
