larger than P18.41, system releases auxiliary
pressure alarm by changing BIT9 of P19.14 to 1
and emergency stop will be applied.
0: Temperature PID
1: Analog P2
2: 485 communication (address 0X201C, writing
of 1000 corresponds to 100.0%, 100.0%
corresponds to the max. output frequency of the
fan)
0: Air compressor mode, the fan inverter starts
and stops automatically based on the
temperature
1: Terminal, the fan inverter starts and stops by
enabling terminals.
2: 485 communication (address 0X201B, write 1
to start, write 3 to stop)
0–120%
Add automatic frequency reduction function.
When output current is larger than automatic
frequency reduction threshold, output frequency
will be adjusted by the regulator to ensure the
running current of the master will not exceed
automatic frequency reduction threshold.
0–8000h
When this parameter is set to "0", the
maintenance time-out function is invalid. If it is
set to non-zero value, then the system will
release maintenance time-out pre-alarm by
changing BIT11 of P19.14 to 1 in cases where
the working time, after part maintenance
pre-alarm, exceeds the value set by P18.45.
P19.00–P19.04 displays the set value of
maintenance time on five kinds of parts. When
the accumulated working time of the part
exceeds the corresponding set value, the system
will release pre-alarm by changing the BIT of
P19.14 to 1. If set to "0", working time pre-alarm
of the parts will be invalid.
