*1 When Pr.128 = "50, 51, 60, or 61", the register is valid.
*2 Instructions will be processed in the order they are received. Thus, the read value of an instruction may differ at different timings if other writing
requests are being made.
*3 "n" indicates a value determined by the station number setting.

5.21.3 Details of the remote input and output signals

The following device numbers are for the station number 1.
For the station number 2 and later, the device numbers are different. (Refer to the manual for the CC-Link master module for
the correspondence between device numbers and station numbers.)
 Output signals (from the master module to the inverter)
Output signals from the master module are as follows. (Input signals to the inverter)

0: Stop command

1: Reverse rotation start
• Functions assigned to terminals RH, RM, RL, JOG, RT, AU, CS, MRS, STOP
and RES are activated.
• These signals are set in the initial setting. Using Pr.180 to Pr.189, input signals
assigned to the device numbers can be changed. Some signals are not
controllable via network depending on the settings of Pr.338 and Pr.339. For
example, RYB reset (terminal RES function) cannot be controlled via network.
When "1" is set in the monitor command (R20), the monitored value is set in the
remote register RWr26 to RWr2F, and "1" is set in the monitoring (RX20). While
"1" is set in the monitor command (RY20), the monitored data is always updated.
When "1" is set in the frequency setting command (RY21), the set frequency
(RWw0) is written to RAM of the inverter. While "1" is set, the set frequency
(RWw0) is always applied.
After the writing completes, "1" is set in the frequency setting completion (RX21).
When "1" is set in the frequency setting command (RY22), the set frequency
(RWw0) is written to RAM and EEPROM of the inverter.
After the writing completes, "1" is set in the frequency setting completion (RX22).
To change the frequency consecutively, be sure to write data to the inverter RAM.

• When "1" is set, a start command is input to the
inverter. When "1" is set in RY0 and RY1, a stop
command is input.
• The signals are fixed. They cannot be changed using
parameters.
