5-54 Understanding IMC-S/23x Setups
Publication 999-122 - January 1997
Note that the contact configuration ( NORMALLY OPEN or
NORMALLY CLOSED ) selected for the home limit switch, overtravel
limit switches, and the drive fault input in the machine setup menu
does not affect the state reported by the dedicated input test. A
normally-closed overtravel limit switch, for instance, will test
ON
in its inactive condition, and OFF when activated.
Press ENTER to terminate the dedicated input test.
Checking the Dedicated Discrete Outputs
The dedicated discrete outputs (drive enable and absolute position
strobe) for each axis are tested using the dedicated output test. When
this test is run, the IMC-S/23x displays
and the state of the drive enable and absolute position strobe outputs
may be toggled between
ON and OFF using the indicated key.
Verify correct operation of the drive enable output with your servo
amplifier. If you are using an absolute position transducer for feedback
on this axis, also verify correct operation of the strobe output with the
REC, REC-4096, TEC-242, or AEC-216.
Press ENTER to terminate the dedicated output test.
Checking Flex I/O Discrete Inputs
Discrete inputs on Flex I/O 1794-IB16 or 1794-IA8 modules are tested
in groups of four using the discrete input test. The IMC-S/23x displays
Toggle to the desired Flex I/O module to test and press ENTER.
If the selected module is not an IB16 or IA8 discrete input module,
an appropriate warning message is displayed and you may select
another block.
!
ATTENTION: The dedicated output test activates the
drive enable outputs directly. Ensure that this is safe
before running this test.
