Hi,
For our new product we want to use your InstaSPIN-FOC with the FAST observer on ACIM motor with the TMS320F280049 (Gen 3). We are currently use the TMS320F28027 (Gen 2).
Unfortunately, the new C2000Ware_MotorControl_SDK (5.01.00.00) doesn't work. The identification with the "is05_motor_id – Motor Parameters Identification" produces anomalous parameters.
The old version of the SDK motorware_1_01_00_18 with the "Lab 2b – Using InstaSPIN out of User RAM and/or FLASH" works very well.
Why has there been a software regression in the algorithm between the old generation and the new ? It is important for us to know when the new C2000 can identify correctly an ACIM motor.
Texas Instruments advised us to start the new designs on the Gen 3 C2000 for end-of-life and performances reasons. Moreover the code is supposed to be compatible between generations:
For help, here our results :
LAUNCHXL-F28027 with the TMDSHVMTRINSPIN:
LAUNCHXL-F280049C with the TMDSHVMTRINSPIN:
The Rr and magnetic current are not valid with the new software. The other parameters seem equivalents.
