15.5.12 Connecting a sensorless servo (FREQROL-E700EX series)


Communication settings
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 (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.
Setting item
PU communication station number
PU communication speed
PU communication stop bit length
PU communication parity check
Number of PU communication retries
PU communication check time interval
PU communication wait time setting
PU communication CR/LF selection
Protocol selection
Operation mode selection
Communication startup mode selection
Communication EEPROM write selection
*1 Setting items are parameter names described in the manual of FREQROL-E700 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.
