| Question: | A Siemens Apogee FLN option board is installed on GPD506 bypass drive so a run command can be initiated through network communications. After a safety circuit fault has been reset, the drive will not run again even though it has been commanded to. Why is this happening? |
| Answer: | This problem will occur while using Siemens Application 2712, if specific criteria is not met. The solution includes adding a wire within the bypass cabinet, and correctly setting up the Siemens command points for initiating a network run command.
Here is a detailed description of the solution:
The GPD506 bypass drive has a terminal block labeled TB1 which contains terminals 3 & 4 for connecting run command wires. Since Serial communications is being used for the run command, there needs to be a jumper installed between terminals 3 & 4 to allow the K5 relay inside the cabinet to be energized. The safety circuit is located before this jumper so if it opens, the run command will be broken and the drive will stop.
The Siemens network will control when the drive can restart again. There are several Siemens command points that have to be set correctly for this to occur, and they are shown below. This information is found in the GPD506/P5 Apogee - FLN Technical Manual (TM4029).
