When speed display is set using Pr. 37 and Pr. 144, the monitor is 1r/min increments.
Set the monitor code to be referenced. (Refer to page 59) By switching on the RYC
signal after setting, the specified monitored data is set to RWr0/RWr1.
⋅ Specify the set frequency. At this time, whether it is written to RAM or EEPROM
is differentiated by the RYD and RYE signals. After setting the frequency to this
resister, switch on RYD or RYE to write the frequency. On completion of
*1
frequency write, RXD or RXE switches on in response to the input command.
⋅ The setting range is 0 to 400.00Hz (0.01Hz increments). Write "40000" when
setting 400.00Hz.
Set the instruction code for execution of operation mode rewrite, Pr. read/write,
error reference, error clear, etc. (Refer to page 55) The corresponding instruction is
executed by switching on RYF after completion of register setting. RXF switches on
on completion of instruction execution.
When a value other than "0" is set in Pr. 544 CC-Link expansion setting, upper eight
bits are link parameter expansion setting.
Example) When reading Pr. 300, instruction code is 0300H.
Set the data specified by the RWw2 instruction code. (When required)
Switch RYF on after setting the RWw2 and this register.
Set zero when the write code is not required.
