Note:
This command does not take effect until you cycle power to the drive,
or send the
RESET
command.
The
DMEPIT
command sets the electrical pitch of the magnets for use with
permanent magnet brushless linear motors. The
DMEPIT
value is required to
convert between linear units and rotary units. The electrical pitch can be
equated to one revolution in a rotary motor. Mechanically, the definition of the
electrical pitch is the linear distance between two magnets comprising a full
magnetic cycle. For example, the illustration below shows an electrical pitch
of 42 mm (
DMEPIT42
).
Figure 43 Linear motor track
Important!
For rotary motors, set the
DMEPIT
to zero (0). The Aries drive
uses the
DMEPIT
parameter as the determinant for which type of motor,
linear or rotary, is connected.
