2. Selection instructions

• Irreversible type: suitable for situations where the motor rotates in one direction, and the system operates in the first or point quadrant. For example, industries such as papermaking, printing, textiles, ignition, plastics, rubber, etc.
• Reversible type: suitable for working environments where motors require rapid braking, frequent starting, fast forward and reverse rotation, and potential energy conversion.
• Simulation cabinet: suitable for unidirectional rotating systems with or without speed measuring generators.
• Digital cabinet: suitable for working systems equipped with speed measuring generators or encoders that require frequent forward and reverse rotation. The digital cabinet can achieve multiple inputs and outputs, facilitating remote control and process control of computers, and meeting the requirements of high-precision speed control and production automation.
