Monitor the Analog Input [Ai1]/[Ai2] Terminal/Pulse Input [PLA] Terminal
How to check if voltage or current is input correctly to the analog input terminals?
Q
How to see the input frequency of the pulse input terminals?
Analog input [Ai1] monitor [d130]/Analog input [Ai2] monitor [d131]
A
The analog voltage/current input values to the [Ai1]/[Ai2] terminals are displayed as 10-bit data
(0 to 1023) with 10 VDC/20 mA as the maximum.
The value of A/D conversion of the analog input can be monitored.
Considering variations in the input circuit, the monitor values are adjusted at the factory so that
!
the maximum value of 1023 is obtained when values slightly larger than 10 VDC/20 mA are
input.

Analog input [Ai2] monitor
Pulse input monitor [d133]
A
Displays the pulse frequency input from the [PLA] terminal in % where the "Pulse frequency
scale [P055]" setting is 100%.
This monitor is always enabled regardless of the setting of "Pulse input, target function selection
[P003]".
For details, refer to "9.2.8 Setting Frequency Command by Pulse Input".
This monitor counts only pulse input from the [PLA] terminal. In case using the [PLB] terminal
!
and checking its input status, set [P003] to "Speed feedback (01)" and monitor "Detect speed
monitor [d008] or "Current position monitor [d030]".Refer to "9.5.8 Using Encoder Feedback" for
details.
