Unattended Start Protection (USP)
When input is active prevents inverter from starting automatically when a run command is present at time
of power-up. Please refer to Fig.4.3.21a for more details.

03-0X =53:
2-Wire Self Holding Mode (Stop Command).
Refer to the
“2-wire operation with hold function” of parameter 00-02.
03-0X =54:
Switch PID1 and PID2
It will switch PID1 to PID2 when PID2 is ON.
03-0X =55:
RTC Time Enable
When 16-13 (RTC timer function) = 2 (DI setting) and RTC Time Enable is ON, RTC timer function is
enabled.
03-0X =56:
RTC Offset Enable
When 16-30 (Selection of RTC Offset) = 2 (DI setting) and RTC Offset Enable is ON, the inverter will run
depending on RTC offset time setting (16-31).
03-0X =57:
Forced Frequency Run
This function enables with the corresponding of parameter of 23-28 and the source of frequency command
of parameter 00-05 set to the value of 5 (PID given, namely the parameter of10-03 needs to be active).
When any one of the multi-function digital input terminal (S1~S6) is set to the value of 16 (the interdiction
of PID function), pump will not depend on feedback to do any PID output adjustment; simultaneously
another one is set to the value of 57 (forced frequency run) and inverter will have the frequency run setting
depending on the parameter of 23-28. Inverter will stop output when digital input terminals (S1~S6) are
removed.
This function is applied to inverter output being controlled by external pressure sensor (eg. differential
pressure switch) when pressure sensor disconnects.
03-0X =58:
Run Permissive Function
When digital input terminal enables, inverter will stop via the set of parameter 08-30 after Run Permissive
Function function is active.
