56 HD3N-TC Series Inverter User Manual V1.0
Ref. code Name Description Setting Range [Default]
F19.19 Stall overvoltage point 220V inverter: 350 - 400 [380V]
380V inverter: 650 - 790 [690V]
If overvoltage occurs during running, properly
increase stall overvoltage gain and decrease F19.19.
Stall overvoltage and braking unit:
Usually when applying braking units to inverter,
please forbid stall overvoltage (F19.18 = 0);
But if feedback energy is too large at loading
moment and delayed energy release of braking
unit, inverter will adopt overvoltage protection. To
avoid protection, enable stall overvoltage and
F19.19 should > action voltage of braking unit.
F = F19.18 × (V
DC
- F19.19)
Auto current limit (F19.20 - F19.21)
Auto current limit is used to limit the load current in real time < F19.21. Therefore inverter will not
trip due to surge current. It is especially suitable for applications with big load inertia or big change
of load.
In auto current limit process, output frequency of inverter may change; therefore, it is recommended
not to enable when stable output frequency is required.
Ref. code Name Description Setting Range [Default]
F19.20 Auto current limit gain 0.000 - 1.000 [0.200]
Output frequency of inverter > F19.21, inverter will limit current to avoid over-current protection.
Adjust F19.20 according to actual load:
If F19.20 is too small, it can not fully limit increase of output current;
If F19.20 is too large, output frequency will fluctuate even system oscillates.
Auto current limt is invalid when F19.20 = 0.
F19.21 Auto current limit threshold 20.0 - 200.0 [150.0%]
Defines the current threshold of auto current limit. The current = F19.21 × rated current of inverter.
When auto current limit is valid, if F19.21 is too small, it may affect the load capacity of inverter.
Terminal detection (F19.23)
Ref. code Name Description Setting Range [Default]
F19.23 Terminal running command detection 0,1 [0]
0: Edge is valid.
