Description
Disable Encoder Fault
Response
R/W
The user can select whether or not the controller
responds to the Encoder fault flags of attached
encoders by setting or clearing the Disable
Encoder Fault Response Flag. This is clear by
default, which means that the controller will
respond to encoder faults in the same way as
drive faults, as described in Disable Drive Fault
Response.
Disable Drive Fault
Response
R/W
The user can select whether or not the controller
responds to the Drive Fault Input (DFI) flag by
setting or clearing the Disable Drive Fault
Response flag. This is clear by default, which
means that the controller will respond to changes
in the DFI flag. (See Drive Fault Input).
Invert Drive Fault Input
Level
R/W
The value of the Drive Fault Input (DFI) flag
(described in this table) will depend on the actual
physical input and the value of the Invert Drive
Fault Input Level (IDFIL) flag. If no current is
flowing to the input and the IDFIL flag is clear
(the default), then the DFI flag will be set. This
would be the case if no drive were attached to
the connector on power up, or if a cable fell off,
or if a standard drive actually faulted. For some
drives, however, the presence of current, not the
absence, indicates a fault. In this case, the user
would wish to set the IDFIL flag, so DFI would be
set if current were flowing to the input.
Invert Motion Direction
R/W
By convention, default wiring, gains, and MULT
values will result in clockwise shaft motion
(viewed from the motor face) when the count is
becoming more positive. But some applications
require that some axes be opposite of this. The
Invert Motion Direction bit will implement this by
inverting the polarity of the signal and feedback
objects attached to the axis. Note that changing
this bit (on or off) on an axis that has an attached
ENC, DAC, or ADC will simply invert the polarity
of those objects by inverting the current MULT or
gain values. This allows the MULT and gain
values to accommodate “unconventional” wiring
but still allow the Invert Motion Direction bit to
change the physical direction. The Invert Motion
Direction bit is saved by
ESAVE
.
Enable CW/CCW
R/W
This flag will change the output of the axis when
configured as a stepper. A setting of 0 means
that step and direction signals are sent to that
drive and a setting of 1 means that CW and
CCW signals are sent to the drive.
Drive Enable Output
R/W
This flag is set by the
DRIVE ON
command and
is cleared by the
DRIVE
OFF
command. Can be
used to manually enable/disable the drive.
Drive Reset Output
R/W
This flag is the same as the
DRIVE
RES
command and is automatically cleared. Can be
used to manually reset the drive.
