DETAILS OF INPUT AND OUTPUT SIGNALS
Set the monitor code to be referenced (Refer to
monitored items will be stored in RWr0, RWr1.
Specify the set frequency or speed (machine speed). At this time, whether to write to RAM or
EEPROM is decided with the RYD and RYE settings. After setting the set frequency in this register,
*1*2
set "1" in RYD or RYE to write the frequency. After writing of frequency is completed, "1" is set in
RXD or RXE in response to the input command.
The setting range is 0 to 590.00 Hz (0.01 Hz increments). Write "59000" when setting 590.00 Hz.
When performing torque control under Real sensorless vector control or vector control with Pr.544
CC-Link extended setting = 0, 1, 12, and Pr.804 Torque command source selection = 3, 5,
specify torque command value. The value is written to the inverter either by RYD or RYE. Pr.805
Torque command value (RAM) and Pr.806 Torque command value (RAM, EEPROM) are also
updated at the same time. The setting range and setting increments depend on the Pr.804 setting.
(Refer to page 80.)
Set the instruction code for execution of operation mode rewrite, Pr.read/write, error reference, error
clear, etc. (Refer to
completing the register setting. "1" is set in RXF after completing the execution of the instruction.
When a value other than "0 (100)" is set in Pr.544, upper eight bits are link parameter extended
setting.
Example) When reading Pr.160, instruction code is H0200.
Set the data specified by the RWw2 instruction code. (When required)
Set "1" in RYF after setting RWw2 and this register.
Set "0" when the write code is not required.
Set the monitor code to be monitored. By setting "1" in RYC after setting, the specified monitored
data is stored in RWr4 to 7.
