Introduction: AS M21 series inverter is a universal inverter designed for China's small power segment motor speed control market, with typical VF control technology, but also using no speed sensor vector control technology, the product integrates Germany technology, Chinese manufacturing technology, light and heavy load integration, combined with the application characteristics of domestic small power motor speed regulation, to further strengthen the reliability of the product, environmental adaptability, can well meet the application needs of various small power segment transmission.

STEPAS-M21

Features:

The high-efficiency and energy-saving operation mode can effectively reduce the motor loss and achieve the maximum power saving rate.

Fast dynamic response, using advanced motor model control, even without PG card can quickly respond to sudden changes in load.

The internal temperature of the IGBT is dynamically calculated to ensure that the module operates under the temperature rise limit

Product parameters

Power input

Input voltage: 380-440V (-15% - +10%), three-phase power supply

Input frequency: 45 -65Hz

Instantaneous current drop: When the three-phase AC3B0-440V power supply is < the input voltage is AC300V, the undervoltage protection is protected after 15ms

Power output

Voltage: OVAC – Input voltage

Overload level: 120% for light load, 1min/10min

Efficiency (full load): ≥ 0.94

Output Frequency Accuracy: +0.1% (Digital Command-10- +45C) ; +0.1% (analog 25+10°C)

Control characteristics

Carrier frequency: 1.1-8 kHz

Frequency setting resolution: 0.01Hz (digital command), +0.06Hz/120Hz (analog command 1bit + unsigned)

Running command channel: operation panel given, control terminal given, communication given

Frequency given channel: operation panel given, digital/analog given, communication given, functional function given

Torque Lift: Automatic Torque Lifting; Manual torque lifting

V/F curves: User-defined V/F curves, linear V/F curves and 3 variable torque characteristic curves

Automatic Voltage Adjustment (AVR): Automatically adjusts the duty cycle of the output PWM signal according to the fluctuation of the bus voltage, thereby mitigating the fluctuation of the grid voltage

Effect of output voltage fluctuations

Instantaneous stop and non-stop processing: when the power is instantaneous, the bus voltage control is used to achieve uninterrupted operation

DC braking capacity: braking current: 00 —— 120.0% rated current

Process PID: It can be used for closed-loop control of process quantities

Common DC bus: The whole series can realize the power supply of multiple inverters sharing the DC bus

Over-current and over-voltage frequency reduction function: when the output current and bus voltage exceed the preset value, the frequency reduction operation of the inverter is implemented.

Sensor alarm function: when the temperature and liquid level sensor detection value exceeds the set protection threshold and holds for 10s, the inverter will alarm and stop

Use environment
