Details of input and output signals
The following device numbers are for station 1. For stations 2 and later, the device numbers are dif-
ferent. (Refer to the Master Module User's Manual for correspondence between the device number
and station number.)
● Output signals (master module to inverter)
Forward rotation command
Reverse rotation command
High-speed operation command
(terminal RH function)
Middle-speed operation command
(terminal RM function)
Low-speed operation command
(terminal RL function)
Jog operation command (terminal JOG
Second function selection (terminal RT
Current input selection (terminal AU
Selection of automatic restart after
instantaneous power failure (terminal CS
Output stop (terminal MRS function)
Start self-holding selection (terminal
Reset (RES terminal function)
Frequency setting command (RAM)
Frequency setting command (RAM,
Instruction code execution request
Error reset request flag
Output signals from the master module (input signals to inverter)
No function is assigned in the initial setting.
0: Stop command
1: Forward rotation start
0: Stop command
1: Reverse rotation start
Functions assigned to terminals RH, RM, RL, JOG, RT, AU, CS, MRS, STOP and RES
Signal names are initial values. Using Pr.180 to Pr.189, input signal functions can
be changed. Note that some of signals do not accept a command from the
network according to the Pr. 338 and Pr. 339 settings. For example, RYB reset
(terminal RES function) cannot be controlled via network.
When "1" is set in the monitor command (RYC), the monitored value is set in the
remote register RWr0, 1, 4 to 7, and "1" is set in the monitoring (RXC). While "1" is set in
the monitor command (RYC), the monitored data is always updated.
When "1" is set in the frequency setting command (RYD), the set frequency (RWw1) is
written to RAM of the inverter. While "1" is set, the set frequency (RWw1) is always
After the writing completes, "1" is set in the frequency setting completion (RXD).
When "1" is set in the frequency setting command (RYE), the set frequency (RWw1) is
written to RAM and EEPROM of the inverter.
After the writing completes, "1" is set in the frequency setting completion (RXE).
To change the frequency consecutively, be sure to write data only to the inverter RAM.
When "1" is set in the instruction code execution request (RYF), processes
corresponding to the instruction codes set to RWw2, 10, 12, 14, 16 and 18 are
executed. "1" is set in the instruction code execution request (RXF) after completion of
instruction codes. When an instruction code execution error occurs, a value other
than "0" is set in the reply code (RWr2, 10, 12, 14, 16, and 18).
When "1" is set in the error reset request flag (RY1A) at an inverter fault, the inverter is
reset, then "0" is set in the error status flag (RX1A). Refer to page 5-466 for operation
conditions of inverter reset.

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