Key Parameters
1. Main Power Ratings:
Input Supply:
Voltage: 3-phase, 380 - 480V AC (±10%).
Frequency: 50/60 Hz.
Output to Motor:
Voltage: 0 - Input Voltage (3-phase, PWM).
Nominal Output Current (IHD): 32.0 A. This is the drive's continuous current rating under defined conditions.
Maximum Output Current (Imax): Typically 150% of IHD for 60 seconds (e.g., ~48A), allowing for motor starting and overload.
Controlled Motor Power: Approximately 15 kW / 20 HP at 400V supply.
2. Control & Performance Characteristics:
Control Methods:
Open-loop V/f Control: Standard for constant torque and variable torque (e.g., fan/pump) applications.
Sensorless Vector Control: Provides improved low-speed torque, better speed regulation, and dynamic response without a feedback encoder.
Frequency Range:
Output Frequency Range: 0 - 590 Hz.
Speed Control Range: Typically 1:100 in sensorless vector mode.
Switching Frequency: Adjustable, typically up to 16 kHz (affects motor noise and drive losses).
3. Key Features:
User Interface: Integrated keypad with multi-line LCD display for parameter setting, commissioning, and status monitoring.
Programmable I/O:
Digital Inputs: Multiple (e.g., 4-6) programmable digital inputs for start/stop, multi-speed, etc.
Digital Outputs: Programmable relay and transistor outputs for status (running, fault) or control signals.
Analog Inputs: Typically 2 (voltage 0-10V and current 0/4-20 mA) for speed reference or process feedback.
Analog Output: Usually 1 (0/4-20 mA or 0-10V) for output frequency or current indication.
Protection Features:
Motor protection (overload, stall, short circuit).
Drive protection (overcurrent, overvoltage, undervoltage, overheating, phase loss).
Electronic Thermal Overload Relay for the motor.
Built-in Functions:
Flying Start.
Automatic Energy Optimisation (AEO).
DC braking.
Programmable multi-speed operation.
PID controller for process control (e.g., pressure, flow).
4. Braking & Filtering:
Braking Chopper: Not integrated as standard on this model. An optional external braking resistor can be connected for dynamic braking/rapid deceleration if the drive supports it (requires checking the specific variant's capability).
EMC Filter: An internal Class A EMC filter is typically integrated as standard to meet general industrial emission limits. For more stringent environments (Class B), an additional external filter may be required.
5. Communication:
Fieldbus Interface: The -SX- variant often indicates a standard model with a removable communication card slot.
Options: Supports a wide range of plug-in communication modules (sold separately), such as Modbus RTU/RS-485, PROFIBUS-DP, DeviceNet, EtherNet/IP, and others, enabling easy network integration.
6. Mechanical & Environmental:
Frame: IP20 / UL Type Open (for mounting inside a protected control panel).
Cooling: Internal fan cooling.
Mounting: Wall or panel mounting.
Operating Temperature: -10°C to +50°C (with derating above 40°C).
Storage Temperature: -40°C to +70°C.
Humidity: <95% RH, non-condensing.
7. Safety:
Complies with relevant sections of IEC/EN 61800-5-1, UL 508C.
May support integrated Safe Torque Off (STO) safety function as a standard or optional feature (must be verified for this specific part number).
8. Typical Applications:
Pumps and fans (HVAC, water treatment).
Conveyors and material handling systems.
Mixers, agitators, and extruders.
Packaging machines.
General-purpose machine automation.
