Finally got some results, in drive status word, bit r899.0 = 1, green light. For these days of strugle, I cann`t say for sure what action had made an effect. Maybe, thermal monitor, after enabling p600 to PTC in CU panel, and also setting p603=r35. From control panel in Starter I am able to turn drive on and output some voltage to passive load, in U/f mode (1317=1). I dont have motor for now. Still, starting NC from MCP, gives message "Axis enable missing" with drive status flags and HMI drive status screen as shown in attachment. r2=31 (ready to turn ON). I believe problem is that in my case drive have no encoder while NC tries to run it as a positioner. For now p1300=20 (sensorless control). I`ve come to this conclusion because "Control requested" flag appears when drive is controlled by NC and turns off when controlled from PC. Also, "speed controller enable NC" on status screen equals zero, so no speed setpoint would be passed to drive. I tried to find meaningful information about this flag through all downloadable documents but this is only info I`ve got. Is this true? So, here is question, is this NC able to control drive with only speed control? While integrating position with NC means? It would seems like driving a spindle with no encoder. What parameters should be set? ------------------------------------------------------------------------------------------ AttachmentStatus.zip (147 Downloads) |

Here is all project, PLC and uploaded machine data files. Looks like machine data is not complete, as there is lot of MD parameters not found in these files. Maybe it will help diagnose the problemAttachmentLinearDrive.zip (151 Downloads) |

Yes, spindle drive can be configured as only speed control without encoder. Integrating position means spindle can be configured as position axis provided encoder is configured. To set parameters please refer below manuals. |
