5.4.2 Autotuning
Before Autotuning,
- Check that there is no load on the crane.
- Set P1.1.1. “Password” = 2156
- Set P1.2.2 “Motor selection” = 1 “Free Travel”
- Set Motor nameplate values P1.2.1, P1.2.4.1- P1.2.4.3
- (if value of P1.2.4.3 “Nom Flux Curr” is not available, set to value 0,00. Parameter P1.2.4.3 will be used if it’s
value differs from 0.00. Otherwise P1.2.4.5 “Motor Cos Phi” value will be used.)
- Set Motor nameplate values P1.2.4.5 “Motor Cos Phi” as it will be used when value of P1.2.4.3 is 0.00.
- Check motor connections
-
Go to parameter P1.2.4.6
- Push Start over 2 seconds to start
Autotuning
- Autotuning can be terminated pushing
Stop-button.
- Autotuning values will be accepted
automatically if Autotuning did not fail
or was not terminated.
-
When parameter P1.2.4.6 has value
“3”, Autotuning has been done
successfully.
-
If parameter P1.2.4.6. has value “2”,
Autotuning has failed or has been
stopped. Check motor parameters and
motor connection.
