| Basic Functions |
Overvoltage/Overcurrent Stall Prevention |
Automatically limits current and voltage during operation to prevent overcurrent or overvoltage trips. |
| Torque Limiting and Control |
Torque control is available in vector control mode. Torque is automatically limited during operation to prevent overcurrent trips. |
| Communication |
RS485 Bus |
Modbus RTU, Modbus ASCII |
| Operation |
Run Command |
Keypad, control terminals or serial communication; selectable by multiple methods. |
| Frequency Reference |
10 frequency reference options, including digital setting, analog voltage, analog current, pulse and serial communication; selectable by multiple methods. |
| Auxiliary Frequency Reference |
5 auxiliary frequency reference options for flexible frequency fine-tuning and combined frequency references. |
| Input Terminals |
Standard: 7 DI terminals, with X7 supporting high-speed pulse input up to 10 kHz; 2 AI terminals supporting 0–10 V input, with AI2 also supporting 0–20 mA input. |
| Output Terminals |
Standard: 1 open-collector output, 1 relay output and 2 AO terminals supporting 0–10 V output, with AO2 also supporting 0–20 mA output. |
| Display and Keypad |
LED Display |
Parameter display |
| Key Lock and Function Selection |
Partial or full keypad locking, with configurable functions for selected keys to prevent incorrect operation. |
| Protection Functions |
Phase-Loss Protection |
Output phase-loss protection |
| Overcurrent Protection |
Trips when the current exceeds 2.0 times the rated VFD current. |
| Overvoltage Protection |
Trips when the main-circuit DC voltage is too high. |
| Undervoltage Protection |
Trips when the main-circuit DC voltage is too low. |
| Overtemperature Protection |
Protection is triggered when the rectifier or inverter module overheats. |
| Overload Protection |
Trips after 60 s at 150% of rated current. |
| Environment |
Installation Location |
Indoors, away from direct sunlight; free from dust, corrosive gases, flammable gases, oil mist, water vapor, dripping water and salt. |
| Altitude |
Below 1,000 m; derate by 1% for every additional 100 m above 1,000 m. |
| Ambient Temperature |
−10°C to +40°C; derating is required above 40°C. |
| Humidity |
<90% RH, non-condensing |
| Vibration |
<4.9 m/s² (0.5 g) |
