Basic Knowledge of DALI

1. DALI Digital Addressable Lighting Interface (DALI) is a two-line bi-directional serial digital communication protocol. Each device is assigned a unique static address in the numeric range 0 to 63, making possible up to 64 devices in a basic system. Addresses may be arbitrarily assigned and devices need not be mapped to contiguous addresses (gaps […]

Basic Structure & Operation of Step Motor

• Basic Structure • Operating Principles In response to each individual control pulse and direction signal, the drive applies power to the motor windings to cause the rotor to take a step forward, a step in reverse, or hold in position. For example, in a 1.8 degree two phase step motor: When both phases are energized with DC current, […]
