6–6 Detection of Abnormal Pulse Outputs
The Position Control Unit outputs pulse trains in accordance with the pro-
grammed data. When tracing an abnormality, the following should be taken
into consideration.
Number of Pulses in
Pulse Train
The Unit only outputs the number of pulses required to reach the desired po-
sition. Count the number of pulses being output with an up/down counter and
check to see if the proper number of pulses is being output.
Frequency of
Pulse Train Output
The frequency of pulse train output can be observed on a synchroscope at
the constant speed interval of the trapezoidal acceleration/deceleration. To
measure the frequency during acceleration and deceleration, an F/V con-
verter and X-Y recorder can be used.
