enables/disables the
Auto-Config process.
0 = disable the Auto-Config process
1 = enable the Auto-Config process
The Auto-Config
process tests motor and
feedback
wiring connections using a series of 6 tests for resolver-based systems
and 8 tests for encoder based systems. To execute the Auto-Config process, the user must first disable the
drive, then set ACONFIG=1, and then enable the drive. The process will
then
execute. The steps of the process are as follows:
Phase 1:
Forced commutation - this phase rotates the motor.
Phase 2: No movement test - if
the motor doesn’t
move, there might be a problem with the motor leads.
Phase 3: Phase current test -
checks to see if the motor leads are
connected
properly.
Phase 4: Counts per cycle test-
checks MENCRES / MPOLES (in encoder
based
systems) or 65536 * MRESPOLES / MPOLES in resolver based systems to
make sure its
accurate.
Phase 5: Direction test - may
fail if two motor lead wires are
switched. User
can change the value of MFBDIR to compensate for failure. See MFBDIR
for more details on correcting a
failure in
this phase.
Phase 6: Resolution accuracy
test - moves the motor 4 revolutions. This
phase
may change the value of MPHASE.
Phase 7: Hall switch test
(encoders with halls only) - may fail if hall
switches are improperly connected. This phase may change the value of
MPHASE or MHINVA / B / C to compensate for
incorrect
results.
Phase 8: Find index test
(encoders only) - moves the motor one
revolution and
searches for index pulse.
