From a digital input perspective, it needs to have just one 'run' command to start and stop the drive. According to the manual, three other inputs can be setup for preset frequencies. Terminal 1 is jumped to terminal 11 Dig input 2: Would like to use this as an 'run 'input. +24 VDC at this terminal should start the drive. It should then look at the preset frequency bits to determine the speed reference. Removing +24 VDC should make it coast to a stop. Dig input 5: Preset frequency bit 1 Dig input 6: Preset frequency bit 2 Dig input 3: Preset frequency bit 3 Here are some of the current settings: P43 – 0 Hz P44 - 60 Hz P45 – 1 P46 – DigIn TrmBlk P47 – Preset Freq P48 – DigIn TrmBlk P49 – Preset Freq P50 – DigIn TrmBlk P51 – Preset Freq T62 – 2 Wire FWD T63 – Preset Freq T64 – Edge trigger T65 – Preset Freq T66 – Preset Freq A410 – 0 Hz A411 – 5 Hz A412 – 10 Hz A413 – 20 Hz A414 – 30 Hz A415 – 40 Hz A416 – 50 Hz A417 – 60 Hz With these settings, as soon as +24 VDC is applied on digital input 2, the drive starts and ramps up to 60 Hz. It coasts to a stop once the 24VDC is removed. It completely ignores the preset frequency bits. This is probably a configuration error as two different drives are behaving exactly alike. Please let me know what needs to be changed so the drive uses the A410..A417 values for the speed. Thanks [/INST] Welcome to ENGAGE, @Sid Gopal ! You should change P049 and P051 to a different Speed Reference source than the one selected for P047 You can for example set P049 to 1 and P051 to 2 No two speed reference can have the same value. Cycle power to the drive after setting the parameters. Hope this helps, ​fuzzy logic Please don't forget to use the LIKE button and highlight the decisive answer : REPLY > Make Best Answer​​ \\n </s>
