5.3. Example of the operation commands setting
The following explains a program to write a running command for inverter operation to the
buffer memory of the master.
The inverter is operated in accordance with the operation commands written to the remote
outputs (addresses 160H to 1DFH).
The following program outputs the command of forward rotation signal to station 1 inverter.
X0000 X000F X0001
[ SET M200] Forward rotation command (RY00).
[ TO H0000 H0160 K4M200 K1] Writes the operation commands to
buffer memory and outputs to the inverter.
5.4. Example of frequency command setting
The following program changes the running frequency of station 1 inverter to 50.00Hz.
Set frequency : K5000 (Decimal number)
The reply code at the time of instruction code execution is set to D2.
M9036 Reads the remote input (RX00 to RX1F)
[ FROM H0000 H00E0 K4M100 K2]
data of buffer memory to M100 – M131.
X0000 X000F
X0001
X0020
[ PLS M302]
M302 Write setting
[ SET M303]
M303
[ MOV K5000 D100 ] Writes set frequency to RWw1.
[ TO H0000 H01E1 D100 K1]
[ SET M213] Switches on the frequency setting command
M113 RAM (RY1D).
[ FROM H0000 H01E2 D2 K1 ] Reads reply code (RWw2) to D2 when the frequency
setting completion (RX1D) switches on.
[ RST M213] Switches of the frequency setting command (RY1D).
[ RST M303]
M9036 Writes M200 – M231 data to the remote outputs
[ TO H0000 H0160 K4M200 K2 ] (RY00 to RY1F) of buffer memory.
*To continuously change the running frequency from the PLC
When the frequency setting completion (ex.: RX1D) switches on, make sure of that the reply
code in the remote register is 0000H and change the set data (ex.: RWw1) continuously.
