text: <s>[INST] 755 - No fault, no alarm - RUNs but produces no output Summary: Drive is ENABLED, but T1/T2/T3 always=0, HIM says there's an output Power the drive. (No on-site firmware updates have been done…running just as it came from the factory – 11.001) Reset the drive, and each peripheral device, to Factory Settings, using the HIM. Measure the DC+/DC- terminals, = ~680VAC Run the HIM-driven commissioning steps (with exception of autotune), and tell the drive that the HIM should be able to start/stop the drive. Attempt to run the drive. Drive front panel shows an output (in this case, 15HZ), and also it shows an output voltage (~120V). HOWEVER THERE IS NO OUTPUT ON THE T1,T2,T3 TERMINALS. Repeated the effort by loading a parameter set from a good drive, and running the drive from Drive Executive (directly connected to drive with ethernet cable between drive and laptop…just as with the prior good drive). All indications are that the drive is running and producing an output, but nothing shows on the output terminals, wired to a motor or open loop. Removed SafeOff connector, and indication changes from Enabled to Not Enabled. So, the summary of the problem is that both the HIM and DriveExecutive show that the drive is creating an output, both in HZ and volts, but nothing is measured on the drive terminals, connected or unconnected. My biggest concern is why the Drive Output Volts parameter, which claims to be representative of the voltage on T1/T2/T3 would differ, at ALL. Cat. No: 20G11ND5P0AA0NNNNN Series A Firmware: 11.001 Serial Number: 40575849 Options: DriveLogix Ethernet/IP SafeOff Encoder 24I/O HIM [/INST] There's nothing wrong with your procedures for startup. We've encountered this problem a couple of times; replacing the drive is the only solution we've discovered. Rockwell has provided no explanation at this point. \\n </s>
