1 Introduction
The HSL-4XMO is a 4-axis motion controller module for HSL sys-
tem. It can generate high frequency pulses (6.55MHz) to drive
stepper or servomotors. As a motion controller, it can provide 2-
axis circular interpolation, 4-axis linear interpolation, or continuous
interpolation for continual velocity. Also, changing position/speed
on the fly is available with a single axis operation.
Multiple HSL-4XMO modules can be used in one HSL system.
Incremental encoder interface on all four axes provide the ability to
correct positioning errors generated by inaccurate mechanical
transmissions. With the aid of on board DSP, the HSL-4XMO can
also perform many real-time applications without compromising
CPU resources. In addition, a mechanical sensor interface, servo
motor interface, and general-purposed I/O signals are provided for
easy system integration.
The HSL-4XMO uses one ASIC (PCL6045) to perform all 4 axes
motion controls and one DSP to communicate with Host PC and
HSL protocol. The motion control functions include linear and S-
curve acceleration/deceleration, circular interpolation between two
axes, linear interpolation between 2~4 axes, continuous motion
positioning, and 13 home return modes. All these functions and
complex computations are performed internally by the ASIC, thus
limiting the impact on the PC’s CPU usage. The DSP can perform
as a motion path-loading manager without consuming Host PC’s
resource. It is more powerful than traditional ASIC-based motion
control card.
