32 | Axm ii / AxP Configurable Motion Control Platform
4.1 PoweR STage
» Innovative Ac-Ac converter without DC bus electrolytic capacitor, which provides instant
availability at power-on and correct input current waveform, in line with the future IEC
555 norm;
» Auto tuning of current limit vs. supply voltage and ambient temperature; single drive for
0-240 Vac (AxP) or 198-460 Vac (AxM) supply;
» 8 kHz carrier power IGBT stage, 16 kHz ripple frequency, built-in full power, limited duty
cycle brake resistor; full power braking chopper;
» Forced ventilation controlled by the drive temperature (the fan is turned on only above
50°C) to limit dust accumulation; the drive temperature is monitored and available for
programmable cycle self-limiting;
»
Full power stage intrinsic protection (overtemperature, short circuit to ground and be-
tween motor wires) with fault condition non volatile storage.
»
Control and power stages have separate and independent power supplies for emergency
shutdown and debugging
»
Real time temperature observer for each power chip, with adaptive current limit.
4.2 ConneCTions
High speed sensor interface (E1 and C1)
» two independent inputs, configurable
» a main general pourpose encoder input (E1) which can be programmed to receive the
following signals:
ENDAT serial encoder (ENDAT 2.1 and 2.2 supported)
SINCOS 5 channel encoder (2 absolute analog tracks, 2 incremental analog tracks, in-
dex)
Resolver
Incremental Encoder
» A secondary encoder I/O (C1 - 2 MHz) wich can be programmed as incremental digital
encoder without commutation tracks or Endat serial encoder.
Encoder simulation output, line driver, with programmable conversion rate with reference to
the main one (allovable on C1 connector)
On the C1 connector there is also the Can interface. See the connection list on par. 7.3
User Interface (connectorsi U1, U2 and P1):
» 2 analog differential programmable inputs
» 2 analog programmable outputs
» 8 digital programmable inputs
» 4 digital programmable outputs
» 1 Watch-dog relay with N.O. and N.C. contacts 1A, 250V
See connection tables beginning on Cap. 5
The encoder
simulation output
can be used
alternatevely
with the auxiliary
encoder input.
