EN1-EN4, Encoder1-4
Description
These groups are "place holders" or connection points
for the different encoders that are available to the
system
In earlier versions of the DMC 2 firmware, there have only been two position
sensors available, RD1 and RD2. RD1 has been hard connected to the regulator
and the commutation of the motor. RD2 has been connected to the Gear box/CAM
input.
With the introduction of ENDAT encoders and incremental encoders in the DMC
firmware it became necessary to be able to select which encoder to use for
respective function. This selection is controlled via the EN1..EN4 groups.
The output from the ENx groups are connected to the other system functions as
follows:
EN NO FUNCTION
EN1 Goes to the pos/speed regulator.
EN2 Goes to the gear box/cam input.
EN3 Free for general use by PL program.
EN4 Free for general use by PL program.
For commutation selection see the Motor.Comm member.
BACKWARD COMPATIBILITY NOTE
Previous versions of the DMC firmware had both Pg.PosOffs and RD1.PosOffs
members pointing at the same variable. Thus executing a REFPOS statement
changed both Pg.PosOffs and RD1.PosOffs. This behavior is preserved if the
EN1.Source has the value 16. It is currently not possible to set the EN1.Source
(if changed) to 16 by other means that resetting the system.
To update an application to be compatible with the new firmware NOT using the
backward compatibility mode you only need to change all references from
RD1.PosOffs to Pg.PosOffs.
FUNCTION
The Enx functions act as a selector switch for redirection of various signals, mainly
for feedback purposes. The default settings are set so that backward compatibility
with DMC1 is achieved.
