FA.20 Motor overload pre-alarm coefficient
FA.21 Motor overload protective coefficient
Long term motor overload would produce serious heat, [FA.21] sets the coefficient of load motor overload protection or
thermal protection; the motor overload protection and motor current curve was inverse, protection curve when FA.21 =
100.0% is shown as follows:
Protection time
60min
2min
So increasing [FA.21] can improve motor overload; overload pre alarm coefficient can be set by [FA.21], when the
motor had reached the degree of overload factor [FA.21] setting, the inverter outputs alarm by terminal, for details
please see Y terminal function.

Malfunction auto-reset times:
0: Off No automatic reset function; manual reset.
1-5: On 1-5 is the automatic reset times;
The inverter would fail or stop during operation due to load fluctuations, voltage fluctuations and other factors. At this
time in order to ensure continuity of system operation, automatic resets of inverter for overload, over current, system
abnormalities, overvoltage, under voltage faults are allowed. The inverter would restart by speed tracking in the process
of self recovery. If the inverter can't restart within the set times, stop output for fault protection; Fault recovery times can
be set up to five times, after 10 minutes running the fault recovery times would be re-recorded and the times before is
automatically cleared. Consecutive failures of restarting might cause harm, so the proposed fault recovery time is 1;
