GENERAL
Description
Motor, Motor interface
The motor group holds information about the motor and resolver combination used.
It is vital that these registers are set up correctly to get maximum performance from
the system.

FUNCTION
Induction motor definitions
Motor.Poles Sets the number of electrical poles within the motor. Four and
six poles are most common.
A negative value indicates compensation for the phase order.
Motor.PPR The commutation logic needs information about the
commutation source resolution (incs/turn), and this should be
set here. A two pole resolver gives 8192 incs/turn.
Motor.PhAlign Represents
the mechanical alignment between the resolver
and the motor. The manufacturer can normally define this
value. If not, it can be measured with a measuring routine
(PL2 coded) included in the SW package.
Motor.IcalR Since the current control part of the system is analog it needs
Motor.IcalS offset compensation. The values for phase R ( Motor.IcalR)
and phase S ( Motor.IcalS) can NOT be defined and must
be measured at every power up of the system. A measuring
routine (PL2 coded) for these parameters is included in the
SW package.
