6. OVERVIEW
The STAC6 is a compact 6 amp/phase step motor
driver with a 167 vdc bus (no transformer)
It uses sophisticated software to “tame”
inherent problems with open loop drives
Existing AMP application software ie; Si
Programmer, SCL and Q are seamlessly
integrated into the design
A brand new, non-legacy application named
CONFIGURATOR simplifies set-up

18. Mid range resonance
Mid range resonance occurs in the 4 to
15 rev/sec range
Occurs at speeds when the drive is not
capable of supplying full current
Occurs in natural resonant bands
Half stepping or microstepping often help
Type of coupling is important
Some compliance was useful

19. Mid range resonance
Amount of load inertia is a factor
Sloppy gear boxes/backlash are bad
Viscous damping often helps

20. Mid range resonance
Mathematical analysis shows insufficient
“damping” is the culprit
How do you add damping without a
feedback device?
Answer: Create a “model” of the plant and
let it run in the background. Compare
actual currents and the model currents.
Inject a small “correction” signal from the
model to raise the damping in the actual.

21. Mid range resonance
Model runs a plant that looks like a spring
– mass combination.
Therefore we information about:
The peak torque of the motor (spring)
The total system inertia ie; Jr + Jl (mass)
Dsp engine then calculates the natural
resonant frequency
Freq = sq. rt.{50Tmax/(Jr +Jl)} / 6.28

25. Under the hood - Self Test
On power-up the drive verifies the
resistance of the windings
On power up the drive verifies the
inductance of the windings
The drive therefore needs this data
File motors- no problem
Non standard motors- You must enter

26. Under the hood - VERIFY
AMP has offered position verification on
3540i – very successful
STAC6 offers more
Position verification
Stall detect
Set the error window (just like a servo with
following error)
R&D project for “Stall prevention”
riding the Torque speed curve to lower speeds.

38. MOTOR HEATING
Step motors have Class B insulation
Class B means 130C winding temperature limit
Classical approach to determine current rating
Suspend motor in free air
Adjust the current for a 80C winding temp. rise in
a 40C environment (allows for 10C hot spot)
No iron losses to contribute to temp. rise

39. MOTOR HEATING
STAC6 approach (motor losses are copper
and iron)
Assumed a motor mounting plate
6” x 6” x .25” for NEMA 23
10” x 10” x .375” for NEMA 34
Verify motor winding temp. remains at or below
130C in a 40C environment
NOTE: This can result in case temperatures up
to 95C

40. MOTOR HEATING
Techniques that mitigate the temperature
rise
Idle current reduction (factory default is 90%)
Motor losses vary with speed
10% reduction in running current causes a 21%
reduction in temp rise.

41. MOTOR HEATING
STAC 6 with Step Motors
Thermal aspects are important now
Motors in indexing applications with some
rest time (idle current reduction on) will
exhibit Si5580 type temperature rises
Motors in constant speed applications will
run hotter and need the mechanical
mount to absorb some of the heat
energy.
