the
CLR
command to clear the error. Once the error is cleared, move the motor out of
the limit switch.
Latch Input
DMX-CAN has high speed position latch input DI2.
This input performs high speed position capture of both pulse and encoder positions but
does not reset the pulse or encoder position counters.
Note:
When StepNLoop mode is enabled, the position value should be ignored.
Use the
LT
command to enable and disable latch feature. To read the latch status, use
LTS
command.
Following are return value description for
LTS
command.
Return Value
Description
0
Latch off
1
Latch on and waiting for latch trigger
2
Latch triggered
Table 7.4
Once the latch is triggered, the triggered position can be retrieved using
LTP
(latched
pulse position) and
LTE
(latched encoder position) commands.
Sync Output
DMX-CAN has a designated synchronization digital output (DO2). The synchronization
signal output is triggered when the encoder position value meets the set condition.
While this feature is enabled, the designated digital output (DO2) cannot be controlled by
user.
Use
SYNO
to enable the synchronization output feature.
Use
SYNF
to disable the synchronization output feature.
Use
SYNP
to read and set the synchronization position value. (28-bit signed number)
Use
SYNC
to set the synchronization condition.
1 – Turn the output on when the encoder position is EQUAL to sync position.
If the synchronization output is done during motion, the sync output pulse will
turn on only when the encoder position and sync position are equal.
2 – Turns output on when the encoder position is LESS than the sync position.
3 – Turns output on when the encoder position is GREATER than sync position.
Use
SYNS
to read the synchronization output status.
