space and provides more than twice the VCL execution speed.
* Six additional VCL-configurable CAN "mailboxes" significantly increases CAN
master capabilities.
* Advanced Pulse Width Modulation techniques produce low motor harmonics, low
torque ripple and minimized heating losses, resulting in high efficiency.
