Signal
Description
RYC
Monitor command
When the monitor command (RYC) is switched on, the monitor value is set to
remote resister RWr0, 1, 4 to 7 and monitoring (RXC) switches on. While the
monitor command (RYC) is on, the monitor value is always updated.
RYD
Frequency setting
command / torque
command
(RAM)
When the frequency / torque setting command (RYD) is switched on, the set
frequency / torque (RWw1) is written to RAM of the inverter.
On completion of write, frequency / torque setting completion (RXD) switches on.
Torque setting command (RAM) is written at the same time during torque control
under real sensorless vector control or vector control.
RYE
Frequency setting
command / torque
command
(RAM, EEPROM)
When the frequency / torque setting command (RYE) is switched on, the set
frequency / torque (RWw1) is written to RAM and EEPROM of the inverter. On
completion of write, frequency / torque setting completion (RXE) switches on.
Torque setting command (EEPROM) is written at the same time during torque
control under real sensorless vector control or vector control.
To change the running speed consecutively, always write data to the inverter RAM.
RYF
Instruction code
execution request
When the instruction code execution request (RYF) is switched on, processing
corresponding to the instruction code set to RWw2, 10, 12, 14, 16 and18 is
executed. The instruction code execution completion (RXF) is switched on after
completion of execution of instruction code. When an instruction code execution
error occurs, a value other than "0" is set in the reply code (RWr2,10,12,14,16,18).
RY1A
Error reset request
flag
If the error reset request flag (RY1A) is switched on only when an inverter fault
occurs, the inverter is reset and the error status flag (RX1A) switches off.
