INVT Goodrive300-21 Series Operation Manual page 62

Goodrive300-21 integrated machine for air compressor Function instruction
pressure is detected to be below P18.06, automatic loading will be applied. During loading running,
the rotation speed of the master will be controlled by pressure PID. P18.07 is the air supply pressure
when setting stable running of air compressor, the inverter keeps exhaust pressure constant by
regulating the rotation speed of the master. Constant pressure control adopts PID algorithm, and the
frequency reference source of the master is set by P00.06=7, the reference source of PID is
P09.00=10, the reference pressure is set by P18.07. The feedback source of PID is P09.02=8, which
is gained by detecting pressure signal. P9.04, P9.05 and P9.06 adopts system default values.
Note: In above figure, the stop mode of the inverter is operated by P01.08, the default setting is
decelerating to stop.
The inverter is in deceleration process under normal stop command and unloading stage; it changes
to coast to stop mode when emergency stop or fault occur.
