Handys speed is 32-400mm/s. Those limits are enforced by the FW. However, due to acceleration time, the top speed is more like 330-350mm/s. I believe 1 unit is 1mm/s when the stroke length is set to 100mm. The max stroke length on Handy is 96mm (but next FW we will increase it to 100mm on Handy 1.0 and 104mm/s on Handy 1.1)
