Functional Features
Power input
Input voltage: (380–460) V (-15% to +10%), three-phase power supply, voltage unbalance < 3%.
Input frequency: 45-65 Hz
Transient Voltage Dip: When the input voltage drops below AC 300V during a three-phase AC (380–460) V power supply, undervoltage protection is activated after 15 ms.
Power output
Motor output voltage: 0 VAC to input voltage, three-phase power supply
Output frequency: V/F control: 0.00–300.00 Hz
Overload rating: 150%, 60s
Output frequency accuracy: ±0.01% (digital command, -10 to +45°C); ±0.1% (analog command, 25±10°C)
Digital input/output
Optocoupler-isolated inputs: 8 channels, with 24V high- and low-level triggering levels that are user-configurable; input functions are customizable. Open-collector outputs: 4 channels, with output functions that are also customizable.
Relay output: 2 normally open channels; 2 normally open and normally closed contacts.
Analog input and output
Analog voltage inputs: 2 channels, -10 to +10 VDC or 0 to +10 VDC, accuracy: 0.1%
Potentiometer voltage: Provides a +10VDC power supply (maximum 20mA) for setting the speed of the potentiometer.
Control characteristics
Control method: V/F control
Starting torque: 2.50 Hz, 150%
Speed regulation accuracy: ±2%; with slip compensation, an accuracy of ±0.5% can be achieved.
Carrier frequency: 2–8 kHz. The default carrier frequency varies depending on the inverter power rating. Frequency setting resolution: 0.01 Hz (digital command); ±0.06 Hz/120 Hz (analog command, 11-bit + unsigned).
Torque Boost: Automatic Torque Boost, Manual Torque Boost
V/F Curve: User-defined V/F curve, linear V/F curve, and five types of reduced-torque characteristic curves
Automatic voltage regulation: Automatically adjusts the duty cycle of the output PWM signal based on fluctuations in the bus voltage.
Automatic frequency adjustment: Automatically adjusts the output frequency to follow fluctuations in the bus voltage, maintaining constant torque.
Transient Power Failure Handling: In the event of a transient power outage, uninterrupted operation is achieved through bus voltage control.
Energy consumption braking capability: For power ratings of 75 kW and below, a built-in braking unit is provided, with an external braking resistor connected externally.
DC braking capability: Braking current: 0.0–120.0% of rated current
Common DC Bus: The entire series enables multiple inverters to share a common DC bus for power supply.
Environmental conditions
Applicable environment: Install in an environment that is free from direct sunlight, dust, corrosive gases, flammable gases, oil mist, steam, and dripping water.
Ambient temperature: (-10～+40)℃
Altitude: <1000m
Ambient humidity: (5–95)%, condensation is not allowed.
Vibration: 3.5 m/s², 2–9 Hz; 10 m/s², 9–120 Hz
