Technical specifications of the NZ2000 series

Series NZ2000 - Small-size vector frequency converters without feedback for general industrial use for a wide range of applications, have the ability to scalar control of the characteristic U / f and vector control without a speed sensor. Scalar mode for controlling the motor speed in most applications, vector mode in cases where high accuracy of maintaining the motor rotation speed is necessary. This device, designed to regulate the speed of rotation of induction motors. The power range of the NZ2000 frequency inverters ranges from 0.4 kW to 250 kW.

Features of the design of NZ2000 frequency inverters :

• Built-in PID controller and PLC, removable remote control;
• Acceleration of the current limit for protection against permanent interference when the current is exceeded;
• Protection during a short-time power failure.
• 2 types of control: Scalar mode (U / f) is the main one and is used for simple motor speed control in most applications. Vector mode is necessary in the case of increased requirements to the accuracy of maintaining the speed of rotation of the motor.
• The output frequency is from 0.1 to 320 Hz.
• Full motor protection: High-precision current measurement, multi-level overload protection, overvoltage and overcurrent protection, short circuit, speed search function, motor thermistor connection and more.
• Advanced interface (6 digital inputs, 2 analog inputs, 1 analog output, 1 digital output, 1 relay output;);
• Built-in RS485 port with support for standard Modbus protocol
• Acceleration / deceleration mode: Linear or s-shaped curve, 4 groups of acceleration / deceleration time; the range is 0.0 ~ 6500.0 sec.
• Acceleration of current limit: Max. limiting the reduction of over-current noise
