Hello, I am using CU310-2 PN drive, I would like to use the encoder on my motor and connected it to CU310-2 PN but i dont know which encoder to use (can I use this). My motor will be placed almost 200 meters far from the plc (300 series), so which communication (TTL, HTL) should I use? Can anyone suggest me which encoder I can directly connect it to my drive and which communication should be used? If there is any connecting schematic that would be really helpful.. Regards..

Hello,
The encoder that was chosen by you, has RS-422 interface with TTL form of signal at output, that covers easily distance up to 1500 meters.
This encoder has convenient communication interface. So there shouldn't be any problem. There's no information about what are you going to measure. Current, Speed, Position or Power factor??? P.S. Here is a link to: X23 where should be connected an encoder. And some significant pages of that document - 223, 224, 227. Msorich |

Hello Msorich, Thank you for the information. Encoder is going to be used to measure the speed of the motor. Based on your answer I made this schematic, is it correct? Can the encoder directly be connected to CU 310-2 PN and then to PLC as shown above? Isn't SMC30 required any where in the schematic? Temperature on CU-310-2 PN, how does it measure the temperature of the motor. Where do I position the temperature sensor, in the cabinet with drive or on the motor? There are also many digital input, is it necessary to use them or what are they used for? |

I'm sorry missed one of questions.
Other terminals are used by encoders that use pure SSI interface to communicate to CU or SMC. P.S.However, considering quite long distance I would prefer following communication layout. See below attached. Msorich AttachmentCommunication_layout_004.pdf (171 Downloads) |
