(2) Operation commands
(Refer to page 61.)
Any of the following commands can be output from the PLC to the inverter as an
operation command any time:
"
Forward rotation (STF)
"
Reverse rotation (STR)
"
Low speed (RL), middle speed (RM), high speed (RH), inverter output halt
(MRS):
The input signals can be changed using Pr. 180 to Pr. 183 (input terminal
(remote output) function selection).
(3) Running frequency
(Refer to page 64.)
The running frequency is written from the PLC to the inverter when it is changed
(Binary in 0.01Hz increments)
The frequency may either be written to E
2
PROM or RAM.
When changing the frequency continuously, always write the data to the inverter
RAM.
(4) Parameter write
(Refer to page 63.)
Functions can be written from the PLC. Note that write during inverter operation will
result in a write error.
Refer to page 171 for the parameter data codes.
(5) Parameter read
(Refer to page 62.)
Functions can be read to the PLC.
Refer to page 171 for the parameter data codes.
