Parameter description
Loading operation is available only after the
motor runs at no-load frequency in the time
set by P18.15.
Setting range: 0–3600s
After the system stops, it is necessary to wait
until the time set by P18.16 elapsed before
restart.
Setting range: 0–3600s
When current discharge pressure is higher
than P18.17, the system indicates pressure
pre-alarm by setting BIT8 of P19.13 to 1.
When current discharge pressure is higher
than P18.18, the system indicates pressure
alarm by setting BIT10 of P19.13 to 1, and
emergency-stop will be applied.
Setting range: 0.00–P18.04
than P18.19, the system indicates
temperature pre-alarm by setting BIT9 of
P19.13 to 1.
When the machine head temperature is
higher than P18.20, the system indicates
temperature alarm by setting BIT11 of P19.13
to 1, and emergency-stop will be applied.
When machine head temperature is lower
than P18.21, the system indicates
low-temperature pre-alarm by setting BIT14 of
P19.13 to 1, and air compressor cannot start.
Setting range: -20–150
It is used to calibrate the displayed value of
P19.10 [actual motor output power].
Setting range: 0%–200%
Set the sampling cycle of temperature PID.
Setting range: 0.0–10.0s
It determines the regulation intensity of
temperature PID regulator, the larger the
value of kp, the stronger the regulation
intensity, however, if it is too large,
temperature oscillation may occur, users can
fine-tune based on the default value.
