text: <s>[INST] 1336F Drive - start stop & change speed - either local through HIM or remote from PLC I have 6 1336F drives that are going from local HIM control only to Local HIM control OR Remote from a PLC. These are 40Hp drives. I have a 10HP drive on the bench right now for testing purposes. I can start stop with a POt and a switch. The 50HP drives have remote HIM's on the door of the panels. My test one has a built in HIM. I put a Y cable into the drive so I can use the same style HIM and a PC using Drive exec. I can start/stop eith by a switch or by the HIM. I can only control speed with a POT. I want to be able to control speed from either the remote HIM or PLC (4-20mA) I also want to start stop either from the PLC or local. I want to use TB3-28, when a 1, use PLC control when a zero use HIM control. SO??? what param am I missing? Thanks George [/INST] I got this part going. Now a different question. When using the PLC, any way to prevent the HIM from Starting it? PLC, I will send 110V to Pins 1 & 28 (Start & Use PLC to control Speed But can I also use an Input to disable the HIM from start control? Thanks George \\n </s>
