Other Parts Discussed in Thread: DESIGNDRIVE
Hi,
What is the suggested upgrade path for our drive design to support an absolute position feedback sensor, such as HIPERFACE, SIN/COS, HIPERFACE DSL, etc?
We current use the TMS320F28052M that includes InstaSPIN and SpinTAC in ROM. We use InsaSPIN FAST for sensorless operation, and SpinTAC Velocity Control. We also support sensored operation using an incremental encoder using the EQEP module. We need to maintain the capabilities we have, and also add support for at least one type of absolute position sensors (such as HIPERFACE, SIN/COS, HIPERFACE DSL, etc.)
It looks like TIs solution to support position sensors is based on “Position Manager”. But it is not clear to me what processors, if any, support FAST, SpinTAC, and “Position Manager”. And what resources are needed to make a robust position sensor solution?
Are there processor(s) that support FAST, SPINTAC, and “Position Manager”?
For example, the TMS320F28004x series lists InstaSPIN and “Position Manager”, but not SpinTAC. This is also a lower end performance processor, so is the “Position Manager” solution limited?
Should I be looking at a higher end processor (like the Delfino TMS320F2833x) for a robust position sensor solution? In which case is there a replacement for FAST and SpinTAC?
Thanks.
