DETAILS OF INPUT AND OUTPUT SIGNALS
Signal
0: Other than forward running (during stop or reverse rotation)
1: Forward running
0: Other than reverse running (during stop or forward rotation)
1: Reverse running
*1
The function assigned to the terminal RUN is activated.
*3
1: The output frequency reaches the set frequency.
*3
1: Overload warning activated
*1
The function assigned to Pr.193 is activated.
The function assigned to terminal FU or terminals A, B, and C is activated.
*1
*1
The function assigned to Pr.194 is activated.
*2
*2
Functions assigned to Pr.313 to Pr.315 are activated.
*2
After "1" is set in the monitor command (RYC), and the monitored value is set in the
remote register Rwr0, 1, 4 to 7, "1" is set in this signal. When "0" is set in the monitor
command (RYC), "0" is set in this signal.
After "1" is set in the frequency setting command/torque command (RYD) and the
frequency setting command/torque command is written to the inverter RAM, "1" is set
in this signal. When "0" is set in the frequency setting command/torque command
(RYD), "0" is set in this signal.
Under Real sensorless vector control or PM sensorless vector control, the following
value is also written to RAM and EEPROM at the same time.
• During torque control: Torque command value
• During speed control: Torque limit value
