DETAILS OF INPUT AND OUTPUT SIGNALS
Turn on the MRS signal to stop the inverter output. (The logic can be changed by the
Pr.17 setting.)
*1
Functions assigned to terminal STOP and RES are activated.
*1
When "1" is set in 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 RYC, the monitored data is
always updated.
When "1" is set in RYD, the set frequency/torque command (RWw1) is written to RAM of
the inverter.
After the writing completes, "1" is set in the frequency setting / torque command
completion (RXD).
*6
Under Real sensorless vector control, vector control, and PM sensorless vector control,
(RAM)
the following value is also written to RAM at the same time.
• During torque control
• During speed control / position control: Torque limit value
When "1" is set in RYE, the set frequency/torque command (RWw1) is written to RAM and
EEPROM of the inverter. After the writing completes, "1" is set in the frequency setting /
torque command completion (RXE).
Under Real sensorless vector control, vector control, and PM sensorless vector control,
*6
the following value is also written to RAM and EEPROM at the same time.
• During torque control
• During speed control / position control: Torque limit value (Pr.544 ≠ "24 or 28")
To change the frequency consecutively, be sure to write data to the inverter RAM.
When "1" is set in 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, 18).
