7.3 Monitoring Input Signals
The status of input signals can be checked with the input signal monitor (Un005). The procedure for the
method of interpreting the display and a display example are shown below.
7.3.1 Interpreting Input Signal Display Status
The input signal monitor (Un005) can be read in the following way. The upper level indicates OFF, and the
lower level indicates ON. All undefined digits are shown in the lower level (ON).
Note: The monitor display and the number of digits shown in a large-capacity
Σ-V SERVOPACK are different from those
for a standard
Σ-V SERVOPACK. Make sure you are reading the displays correctly when checking signal operation.
Note: Input signals use the following circuit configuration.
• OFF: Open
• ON: Short-circuited
