First G120 for me, I'm mostly on the Logix side. CPU 1516-3 PN/DP, G120 with a CU240E-2 PN and a PM240-2, TIA V17 with Startdrive, standard telegram 1. Drive is green in device view, no buffer entries.
From the PLC I write control word 16#047F and speed setpoint 16#2000 into the telegram with DPWR_DAT. The status word comes back, r0052 in Startdrive shows bit 0, ready to switch on, and that's where it sits. Motor never turns, no fault, no alarm. I re-assigned the device name from scratch and checked p0840 is r2090.0 so the ON command comes off the telegram.
In Logix I'd set the Start bit and go. What does the G120 want that I'm not giving it? Any pointers welcome.
Is the speed setpoint scaled right? On my bench drive 16#4000 is 100 percent, so 16#2000 is only half, and I once had a minimum speed set that made it look dead.
