Plc Function - Mitsubishi Electric 800 Series Instruction Manual

5.14.17

PLC function

The inverter can be run in accordance with a sequence program.
In accordance with the machine specifications, a user can set various operation patterns: inverter movements at signal
inputs, signal outputs at particular inverter statuses, and monitor outputs, etc.

Desired values can be set.
Because devices D206 to D255 used by the PLC function can
be mutually accessed, the values set to Pr.1150 to Pr.1199 can
0 0 to 65535
be used by the sequence program. The result of performing
calculation by a sequence program can also be monitored by
Pr.1150 to Pr.1199.
(A) Application parameters
Description
The SQ signal is enabled by input from a
command source (external input terminal/
communication).
The SQ signal is enabled by input from an
external input terminal.
When the pulse train is input from terminal
JOG, the number of sampled pulses can be
converted.
The result of conversion is stored to SD1236.
"Number of sampled pulses" = "input pulse
value per count cycle"  "pre-scale setting
value (Pr.417)" "unit scale factor (Pr.416)"
