The control mode of the ATV12H018M2 frequency converter is flexible and diverse, suitable for different load requirements. The following are its core control modes and features:

Basic Control Modes
V/F Control (Voltage/Frequency Ratio Control)

Features: The most basic control mode, realizing the speed regulation of the motor by fixing the ratio of voltage to frequency (such as U/f = constant).

Application Scenarios: Suitable for quadratic torque loads such as fans and pumps, and scenarios where precise speed control is not required.

Advantages: Simple control, high stability, and the starting performance can be optimized through parameter adjustment.

Sensorless Flux Vector Control (SVC)

Features: Based on the mathematical model of the motor, achieving more precise control by calculating the excitation component and torque component of the stator current.

Application Scenarios: Suitable for constant torque loads (such as conveyors, mixers), requiring a higher starting torque (up to 150% of the rated torque at 0.5Hz).

Advantages: Good lowspeed torque characteristics, fast dynamic response, and supporting closedloop speed control (external encoder is required).

Starting and Stopping Modes
Starting Modes

Linear Ramp: Smooth acceleration to the set frequency, suitable for most loads.

S Curve Ramp: Adopting nonlinear acceleration/deceleration during starting and stopping to reduce mechanical shock (such as elevators, cranes).

Quick Start: Supporting emergency start requirements, and it needs to be used with a braking unit.

Stopping Modes

Free Stop: Cutting off the output, and the motor stops naturally due to the inertia of the load.

Deceleration Stop: Decelerating to stop according to the set ramp, and DC braking can be set (to prevent the motor from coasting).

III. Communication and Remote Control

Builtin Communication Interfaces

Modbus RTU: Realizing device networking through the RJ45 or RS485 port, supporting the masterslave mode (such as remote control by PLC).

CANopen (Optional Expansion): Used in industrial automation networks to achieve synchronous control of multiple frequency converters.

I/O Control

Digital Input: Supporting 3 programmable inputs (such as forward and reverse rotation, multispeed control).

Analog Input: 1 input of 010V or 420mA, used for speed regulation by an external potentiometer or sensor.

Relay Output: 2 programmable relays, which can be used for fault alarm or status indication.

Advanced Functions
PID Closedloop Control

Realizing the closedloop regulation of physical quantities such as pressure and flow through the builtin PID controller (external sensor is required).

Typical Applications: Constant pressure water supply systems, temperature control.

Automatic Energysaving Mode

Automatically optimizing the V/F curve according to the load change to reduce the motor energy consumption (especially suitable for light load operation scenarios).
