Program example for monitoring the output frequency
The following explains a program to read monitor functions of the inverter.
The following program reads the output frequency of station 1 inverter to D1.
Output frequency read code: H0001 (hexadecimal)
Refer to
for the monitor codes.
(Example) The output frequency of 60Hz is indicated as H1770 (6000).
Program example for parameter reading
The following program reads
Pr.7 Acceleration time
of station 1 inverter to D1.
•
Pr.7 Acceleration time
reading instruction code: H07 (hexadecimal)
• Refer to the Instruction Manual (Detailed) of the FR-A800/FR-F800 inverter for details of the parameter instruction
codes.
• The reply code at the time of instruction code execution is set to D2. (Refer to
NOTE
• For parameters having numbers 100 and later, change their link parameter extended settings (set them to other than H00).
Refer to the Instruction Manual (Detailed) of the FR-A800/FR-F800 inverter for details.
Set monitor code (H01) of output frequency
to RWw0.
Turn on the monitor command (RY0C)
Read output frequency (RWr0) to D1
when the monitoring (RX0C) turns on.
