This property defines the axis velocity maximum value which when exceeded triggers a Watch Dog condition. The property is implemented as a safety mechanism preventing instantaneous position jumps. Typically its value should be about ten time bigger then VMAX.
 | IMPORTANT |
| The Velocity Safety Limit causes Watch-Dog activation, Therefore it is from absolute importantce to set it to right value (10*Vmax)! |
 | NOTE |
Note that VelocitySafetyLimit and VOSPD should be bigger than: 1000/ser.cycletime/VFac. In cases where vfac is set too low regular velocity values can trigger these. Issue 5267 |
