GOT-F900 SERIES (CONNECTION) Connection of FREQROL (S500/E500/A500) Inverter 13
13-8
2) Communication setting in inverter
Set the following parameters using the PU (parameter unit) to realize the communication
specifications of the GOT-F900.
Though these parameters can be monitored from the GOT-F900, do not change them. If they are
changed, communication with the GOT-F900 is disabled.
a) S500 Series
- Parameters n1 to n7 and n10 to n12 are set in the built-in parameter unit.
- When parameters are monitored from the GOT-F900, they correspond to parameters Pr. 331
to Pr. 337 and Pr340 to Pr. 342 respectively.
