Mounting and Wiring

Mounting Dimensions

Refer to the diagram for mounting dimensions (Unit: mm). Ensure proper clearance. Note: Do not touch wiring terminals when powered on or within 15 minutes after power off due to potential electric shock. Installation screws are M4.

Main Circuit Wiring

Terminal Definitions:

L1, L2, L3: Three-phase power supply input.
L1, L3: Single-phase power supply input.
U, V, W: VFD output terminals connecting to the three-phase motor.
PE: Grounding terminal (must be reliably grounded with resistance < 10Ω).
P+, PB: Brake resistor terminals.

Important Notes:

No phase sequence requirement for input power.
Optional parts include circuit breaker, contactor, AC reactor, fuse, and brake resistor.
When motor cable length exceeds 100m, an AC output reactor is recommended near the converter to mitigate resonance.
Do not connect capacitors or surge absorbers to the output terminals (U, V, W) as it can damage the inverter.
Protective grounding conductor must be sized appropriately and use yellow/green cable.

Control Loop Wiring

Terminal Definitions:

A, B: RS485 communication terminals (without isolation).
24V, COM, 0V: Power supply for control terminals (24V/COM for NPN, 0V/COM for PNP input).
X1-X5: Bidirectional digital input terminals (support normal input, not high-speed pulse).
Y1: Open collector output terminal (not high-speed pulse).
TA, TB: Relay output terminals (AC 250V/3A, DC 30V/1A).
10V: Provides 10V voltage output to GND.
AI1, AI2: Analog voltage input terminals (0-10V). AI1 also supports 0-20mA (selectable via jumper). AI2 only supports voltage.
AO: Analog voltage output terminal (0-10V).

Operation Panel

Keyboard Layout and Functions

The operation panel allows control of starting, speed regulation, stopping, parameter setting, etc. It features 8 keys:

Programming/Exit: Enter/exit programming mode.
Save/Switch: Save parameters or move to the next menu.
Forward Run: Start forward operation.
Stop/Reset: Stop operation or reset faults.
Increase: Increase value or pause frequency.
Decrease: Decrease value or pause frequency.
Shift/Monitor: Edit data bits or switch display/monitor parameters.
Frequency Setting: Adjust frequency via panel potentiometer.

LED Indicators

The panel includes 5-digit LED displays and status/unit indicators:

Status Indicators: RUN (operation), REV (direction), REMOT (command source), TUNE (tuning/fault status).
Unit Indicators: V (Voltage), A (Current), Hz (Frequency), R/MIN (Speed/%).

Alarm Analysis and Fault Handling

When the inverter encounters an issue, the LED display shows a fault code. The fault relay activates, and output stops. The motor stops freely if rotating.

Common Fault Codes:

Code	Name	Reason	Solution
Err01	Acceleration Over Current	Output circuit short/ground, short acceleration time, low voltage, etc.	Remove peripheral faults, tune motor parameters, increase acceleration time, adjust voltage, use speed tracking start.
Err02	Deceleration Over Current	Output circuit short/ground, short deceleration time, no brake unit/resistor, etc.	Remove peripheral faults, tune motor parameters, increase deceleration time, adjust voltage, add brake unit/resistor.
Err03	Constant Speed Over Current	Output circuit short/ground, low voltage, sudden load, etc.	Remove peripheral faults, tune motor parameters, adjust voltage, cancel sudden loading.
Err04	Acceleration Overvoltage	High input voltage, external force driving motor, short acceleration time, no brake unit/resistor.	Adjust voltage, cancel external force, add brake resistor, increase acceleration time.
Err05	Deceleration Overvoltage	High input voltage, external force driving motor, short deceleration time, no brake unit/resistor.	Adjust voltage, cancel external force, add brake resistor, increase deceleration time.
Err06	Constant Speed Over Voltage	High input voltage, external force driving motor.	Adjust voltage, cancel external force, add brake resistor.
Err07	Buffer Resistance Overload	Unstable supply voltage, main control board abnormal.	Adjust voltage, contact support.
Err08	Under Voltage	Instantaneous power failure, input voltage out of range, abnormal bus voltage, etc.	Reset fault, adjust voltage, contact support.
Err09	VFD Overload	Load too large, motor stall, VFD selection too small.	Reduce load, check motor/mechanical condition, choose higher power VFD.
Err10	Motor Overload	Incorrect motor protection parameters, load too large, VFD selection too small.	Set parameters correctly, reduce load, check motor/mechanical condition, choose higher power VFD.
Err11	Input Lack Phase	Abnormal input power supply, drive board abnormal, etc.	Check peripheral circuit, contact support.
Err12	Output Lack Phase	Abnormal motor lead, unbalanced output, drive board abnormal, module abnormal.	Remove peripheral faults, check motor windings, contact support.
Err13	Overheated Radiator/Module	High ambient temp, blocked air duct, fan damage, module damage.	Reduce ambient temp, clean air duct, replace fan/module.
Err18	Short Circuit Fault of Motor to Ground	Motor short circuit to ground.	Replace motor or cable.
Err44	Communication (Timeout) Fault	Upper computer not working, cable abnormal, incorrect parameters.	Check wiring, cable, and parameters.
