ZM-7205A BLDC Motor Driver Comprehensive User Manual zm7205a manual

| Terminal | Description | Terminal | Description | | :--- | :--- | :--- | :--- | | | AC80-250V Power | Motor Winding (U,V,W) | Connect to Motor | | Hall Signal (H+,H-,HU,HV,HW) | For Hall Sensors | +5V1, VSP, GND1 | Speed Control | | EN, DIR, X1/BK | Enable, Direction, Brake | FG (+), FG (-) | Speed Pulse Output | | ALM (+), ALM (-) | Alarm Output | +5V2, GND2, HU, HV, HW | Hall Sensor Power |

Due to transportation, allow the driver to acclimatize to ambient temperature for 12 hours before applying power if there is a risk of condensation.

The is a high-voltage, high-efficiency Brushless DC (BLDC) motor driver engineered for precision control of medium-power industrial motors. Operating on an integrated high-voltage DC bus (typically 310V DC derived from a 220V AC input), it supports motors up to 1100W with a maximum current threshold of 5A . | Button | Label (common) | Function |

Drives three-phase BLDC motors with or without Hall effect sensors.

The is a high-performance, mid-power motor controller designed to drive both sensored and sensorless three-phase BLDC motors. Utilizing large-scale integrated circuits to replace traditional hardware designs, the ZM-7205A Driver offers superior anti-interference capabilities, rapid response times, and highly stable thermal profiles even under high-current loads.

L.oFF : Open-loop control (Voltage scaling). L.oN : Closed-loop speed regulation via PID. Modulation Strategy Calculate by counting permanent magnets divided by 3

Rotational Speed=150060=25 revolutions per secondRotational Speed equals 1500 over 60 end-fraction equals 25 revolutions per second

Use the built-in knob to adjust speed.

Connect to SV, GND, and +5V terminals. Analog Input: DC input to the SV terminal.
