■12. Connecting a sensorless servo (FREQROL-E700EX series)
Make the communication settings of the sensorless servo (FREQROL-E700EX series).
Be sure to perform the inverter reset after updating each parameter.
(1) Communication port and corresponding parameters
GOT connection destination
PU connector
FR-E7TR
(RS-485 terminal block)
(2) Communication settings of sensorless servo
Set the following parameters using the PU (operation panel or parameter unit).
Do not change these parameters, even though they can be monitored from the GOT. If they are changed,
communication with the GOT is disabled.
