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
(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.
*1 Setting items are parameter names described in the manual of sensorless servo (FREQROL-E700EX series).
*2 Settings on the GOT can be changed.
When changing the settings on the GOT, be sure to change the parameters on the inverter to correspond with the GOT settings.
*3 Sensorless servo (FREQROL-E700EX series) default values (No need to change)
