Comprehensive User Guide for Jintech JTE280 Series Variable Frequency Drive (VFD)

I. Control Panel Operations and Parameter Management

1. Panel Interface Fundamentals

The JTE280 features two panel configurations (Fig.4-1/4-2) with essential controls:

• RUN: Start operation (requires P0.03=0)
• REV/JOG: Reverse/Jog (configured via P3.52)
• STOP/RESET: Halt/Reset faults
• PRGM: Access parameters (5-sec hold locks keyboard)
• ▲/▼: Adjust values (real-time speed adjustment)
• <<: Toggle monitoring parameters (J-00~J-11)

2. Factory Reset Procedure

Execute through hierarchical menu:

graph TD
    A[Press PRGM] --> B[Locate P3.01]
    B --> C[Set tens-digit=1 for default]
    C --> D[Confirm with DATA]
    D --> E[Set tens-digit=2 to clear faults]

3. Security Configuration

• Password Protection: Set P0.00 (0001-9999)
• Access Levels (P3.01 units-digit):
• 0: Full access
• 1: Only P3.01 adjustable
• 2: Only P0.02+P3.01 adjustable
• Keyboard Lock: 5-sec PRGM hold

II. External Control Implementation

1. Terminal-Based Motor Control

Critical Parameters:

P0.03 = 1      ; Terminal control mode
P4.08 = 0      ; 2-wire control scheme 1

Wiring Specification:

• Forward: FWD-DCM short
• Reverse: REV-DCM short
• Stop: Open circuit

2. External Potentiometer Configuration

Parameter Chain:

P0.01 = 0      ; Potentiometer mode
P1.01 = 1.00   ; VI gain default
P1.02 = 0.00V  ; Min voltage
P1.05 = 50.00Hz; Max frequency

Connection Protocol:

1. Potentiometer wiper → VI terminal
2. Potentiometer V+ → +10V terminal
3. Potentiometer V- → ACM terminal

Recommended: 10kΩ linear potentiometer

III. Fault Diagnosis Matrix

Code	Description	Root Causes	Corrective Actions
E-01	Acceleration OC	Load surge/short acc.time	Increase P0.17, inspect mechanics
E-02	Deceleration OC	Regenerative energy	Enable P5.02 overvoltage stall
E-11	DC Bus UnderV	Input <305V	Verify supply, set P5.07=1
E-12	DC Bus OverV	Rapid deceleration	Adjust braking parameters
E-15	IGBT Overheat	Cooling failure	Clean vents, reduce loading

Troubleshooting Flow:

1. Resolve hardware issues
2. Press STOP/RESET to clear
3. Analyze history (P6.00-P6.11)

IV. Advanced Application Techniques

1. Multi-Speed Programming

P4.00=1  # M11=Speed-bit1
P4.01=2  # M12=Speed-bit2
# Speed1: M11 ON
# Speed2: M12 ON
# Speed3: M11+M12 ON

2. Winding Control (Textile Applications)

P9.00=1      ; Enable wobble
P9.04=10.0%  ; Amplitude
P9.06=5.0s   ; Cycle time

3. PID Pressure Regulation

P7.00=1      ; Enable PID
P7.10=0.85   ; Proportional gain
P7.16=25.00  ; Preset frequency

Key Operational Notes:

1. High-altitude (>1000m) requires derating (Fig.1-3)
2. Long cables (>30m) mandate output reactors (Sec.1.3.8)
3. Braking resistors must comply with Table 3-25 specifications

This guide synthesizes critical operational knowledge from the 117-page manual. For complete technical specifications, refer to Chapter 9 (Application Examples) and Appendix (MODBUS protocols). Proper implementation of these procedures will optimize drive performance while ensuring operational safety.
