Double Motor Control Unit
01Overview
Board driving two motors in sync, with independent operating modes.
CND-1102 Double Motor Control Unit is an industrial automation control board designed for dual DC motor drives used in pergola and awning systems. It operates within a 12–24V DC input voltage range and supports up to 10A motor current per channel. With its built-in dual Hall-Encoder input, it independently tracks the position of both motors. It features three different operating modes: Synchronous, Single (independent), and Free (manual). Real-time position and status information is displayed on the built-in OLED screen. Integration with smart home systems is provided through dry contact and shutter inputs.

Datasheet notes
- The board must be mounted inside an enclosure. Do not expose directly to outdoor conditions.
- Before connecting motors, ensure the supply voltage and polarity are correct.
- Encoder cable length should not exceed 3 meters; use shielded cable for longer distances.
- The + and − terminals on CN4 are doubled for parallel connection. Both + terminals and both − terminals are connected to each other.
- Dry contact inputs must be potential-free (volt-free).
- Always perform connection check in Free Mode before commissioning.
- In SYNC mode, it is recommended that both motors are of the same type and same RPM specifications.
- Motors should not be operated without setting the limits.
