Captain, By giving a drive 10V and then flipping to 0V is really no different than a standard analogue input, the only concern you will have is how fast you want the drive to ramp to/from the 10V setpoint. Key parameters: P1080 Min Freq P1082 Max Freq (She'll no take no more) P1120 Ramp-up time P1121 Ramp-down time Check out the Getting Started guide for further info: http://support.automation.siemens.com/WW/view/en/38644522 Scottie |

I have to set set the parameters of the motor too, right ?! And the control by the analog input of the mm420 is always enabled or need a parameter to enable ?! Thanks in advance! |

Dear Graeme, I would like to correct something. P0731 = 52.2 for Inverter running feedback. ** attched settings of P0731. Dear Cpt_KriK, As you told, you want to use the MM420 for soft-staring and soft-stopping the motor. Do you want finally to run the motor on F=50Hz? If yes. Why don't you use the soft-starters (3RW) series. Regards. AttachmentP0731.pdf (158 Downloads) |
