Full Coil Configurations
Lower speeds is desired. This configuration is also referred to as full chopper. In full coil mode, the
motors should be run at only 70% of their rated current to prevent overheating.

Connections to 8-lead Motors
8 lead motors offer a high degree of flexibility to the system designer in that they may be connected in series
or parallel, thus satisfying a wide range of applications.
Series Connections
A series motor configuration would typically be used in applications where a higher torque at lower speeds
is required. Because this configuration has the most inductance, the performance will start to degrade at
higher speeds. In series mode, the motors should also be run at only 70% of their rated current to prevent
overheating

Parallel Connections
An 8 lead motor in a parallel configuration offers a more stable, but lower torque at lower speeds. But
because of the lower inductance, there will be higher torque at higher speeds

Power Supply Selection
The Microstep Driver can match Large and small size stepping motors (from Nema size 17 to Nema size 34).
To achieve good driving performances, it is important to select supply voltage and output current properly.
Supply voltage determines the high speed performance of the motor, while output current determines the
output torque of the driven motor (particularly at lower speed). Higher supply voltage will allow higher
motor speed to be achieved, at the price of more noise and heating. If the motion speed requirement is low,
it
’
s better to use lower supply voltage to decrease noise, heating and improve reliability.
