Function Description
Setting Range [Default]
F19.45
Motor auto dehumidifying humidity
F19.46 - 100.0 [80.0%rm]
F19.46
Motor auto dehumidifying humidity delay
0.0 - 30.0 [5.0%rm]
F19.47
Motor auto dehumidifying time
0.1 - 1200.0 [120.0min]
F19.48
Motor auto dehumidification stop interval
0.0 - 6000.0 [0.0h]
When F19.48 = 0, the dehumidification according to the stop interval is invalid.

F20.00
Overload pre-alarm detection
00000 - 31111 [00000]
Unit: Overload pre-alarm detection
•
0: It is active all the time in running status.
•
1: It is active only at constant speed.
Ten: Overload pre-alarm action
•
0: HD3Z doesn’t alarm and continues running when detecting an active overload signal.
•
1: HD3Z alarms and stops running when detecting an active overload signal.
Hundred: Overload detection threshold
•
0: Relates to rated current of motor (alarm E0019: Motor overload).
•
1: Relates to rated current of HD3Z (alarm E0017: Inverter overload).
Thousand: Motor type
•
0: Standard motor. As the cooling effect of the standard motor deteriorates at low speed, HD3Z will
automatically make regulation to the time of motor overload protection.
•
1: Variable frequency motor. The cooling effect of the variable frequency motor is not affected by the
motor speed due to its forced cooling potential, HD3Z will not automatically make regulation to the time
of motor overload protection.
Ten Thousand: Overload protection
•
0: Enable inverter overload protection and motor overload protection.
•
1: Enable inverter overload protection; Shield motor overload protection.
•
2: Shield inverter overload protection; Enable motor overload protection.
•
3: Shield inverter overload protection and motor overload protection.
F20.01
Overload pre-alarm detection value
20.0 - 200.0 [150.0%]
Defines the current value for overload pre-alarm. It relates to rated current of motor or inverter.
F20.02
Overload pre-alarm detection time
0.0 - 60.0 [5.0s]
When output current of HD3Z > F20.01, and duration F20.02, HD3Z will report E0017 fault (Inverter
overload) or E0019 fault (Motor overload).
F20.08
The detection base of lack of input
0 - 80 [30%]
F20.09
The detection time of lack of input
1.00 - 5.00 [1.00s]
F20.08 is percentage related to rated voltage of HD3Z.
When HD3Z detects certain input voltage does not hit the detection base F20.08, and exceeds the preset
detection time (F20.09), HD3Z alarms E0015 fault (Lack of input).
•
F20.08 = 0, HD3Z will not detect input phase loss fault.
F20.10
The detection base of lack of output
0 - 100 [20%]
F20.11
The detection time of lack of output
1.00 - 20.00 [3.00s]
F20.10 is percentage related to rated current of HD3Z.
When HD3Z detects certain output current does not hit the detection base (F20.10), and exceeds the
detection time (F20.11), HD3Z alarms E0016 fault (Lack of output).
•
F20.10 = 0, HD3Z will not detect output phase loss fault.
