The motor encoder indicates the absolute position within one motor
revolution. If the motor covers more than one revolution during a
positioning movement, the position sensing system must be referenced
with an external rough pulse signal.
If a multi-pole resolver has to be referenced, the resolver angle KK96
(available from software version1.6) has to be connected up to the
motor encoder position detection instead of the rotor position KK90
(P182=96). If KK90 were used, the zero pulse would always be
detected in the pole pitch in which the resolver happens to be
positioned when switched on.
In one mechanical motor revolution, the resolver angle makes the same
number of revolutions as the number of pole pairs of the resolver. The
number of pole pairs of the resolver must therefore be taken into
account in the denominator of the AVWF factor (P180.2).
Position detection uses the zero passage of the connected position
angle as a substitute for a zero pulse. It thus detects the same number
of zero pulses as the resolver's number of pole pairs. The desired zero
pulse is selected with the rough pulse.
The following table provides an overview of the homing modes:
Homing Mode
To right of BERO
P183 = xx11
To left of BERO
P183 = xx21
When using homing mode in technology option F01 or in SIMATIC M7,
the machine data MD5 setting must be identical to P183 [821.3].
The home position is the first rotor zero position
after the negative edge of the rough pulse. The
traversing direction must be positive.
