4. Verify that the output is off.
Repeat this process for each discrete output that you
are using:
__O1 __O2 __O3 __O4
__O5 __O6 __O7 __O8
2.7.3 Cycle Ready
CYCLE READY cannot be checked without a
program. The
User's Manual discusses this topic.
Later, when you are familiar with programming, you
can write a program that turns CYCLE READY on.
Check this output at that time.
2.7.4 Checking STATUS
Check STATUS later in this chapter when the BDS5 is
active. The STATUS output will turn on when you
enable the BDS5.
2.7.5 Checking Encoder Output
Check the encoder output with a two-channel
oscilloscope. Place Channel 1 on OUTA and Channel
2 on OUTA'. Rotate the motor by hand. You should
see the encoder output on your scope. Repeat this
process for OUTB and OUTB' and for OUTZ and
OUTZ'. Note that OUTZ changes state only at one
point during a full motor revolution.
2.7.6 Checking Encoder Input
If you have encoder input, connect your encoder to
Connector C1. The encoder should not be moving.
Type:
P PEXT
Now rotate the encoder. Type:
P PEXT
PEXT should have changed when you rotated the
encoder shaft.
If the results are not what you expected, use an
oscilloscope to verify that all four signals are reaching
Connector C1.
Note that encoder equivalent inputs are not available if
your system has analog input.
2.7.7 Checking Pulse Input (Optional)
If you have a pulse input option, connect your pulse
input to Connector C1. Stop the pulse train. Type:
P PEXT
Now inject a few pulses. Type:
P PEXT
PEXT should have changed by the number of pulses
you injected. If the results are not what you expected,
make sure that you have set the pulse format switch
properly. Then, use an oscilloscope to verify that all
four signals are reaching Connector C1.
2.7.8 Checking Analog Input
(Optional)
If you have analog input, connect your input voltage to
Connector C2. Adjust the voltage to zero volts. Type:
P PEXT
Wait a few seconds and type:
P PEXT
PEXT should not have changed or should have
changed very little. Now raise the input voltage to a
few volts. Type:
P PEXT
and PEXT should have changed much more than it did
with the input zeroed.
