Contents 2LD556 Microstepping Driver Manual V1.0 2. Specifications 1. Introduction, Features and Applications Electrical Specifications (Tj = 25℃/77℉) Introduction The 2LD545 is a versatility fully digital stepping driver based on a DSP with advanced control Parameters algorithm. The 2LD545 is the next generation of digital stepping motor controls. It brings a unique 2LD545 Min Typical Max Unit level of system smoothness, providing optimum torque and nulls mid-range instability.

Contents Contents Half Coil Configurations Driver Controller ● PUL+ 驱动器与上位控制器的连接 PULS PUL- 电缆最好选择带屏蔽，屏蔽 DIR+ DIR 层连接标准大地或上位控 DIRENB+ 制器接地端。 ENBL ENB- ● As previously stated, the half coil configuration uses 50% of the motor phase windings. This gives lower inductance, hence, lower torque output. Like the parallel connection of 8 lead motor, the torque output will be more stable at higher speeds. This configuration is also referred to as half chopper.

On the other hand, if unregulated supply is used, one may use a power supply of lower current rating than that of motor (typically 50%～70% of motor current).
