This property defines the axis velocity maximum value that triggers a Watchdog condition when exceeded. The property is implemented as a safety mechanism for preventing instantaneous position jumps. Typically its value should be about ten time greater than VMAX.
 | IMPORTANT |
| The Velocity Safety Limit causes Watchdog activation. It is therefore imperative to set it to the correct value (10×Vmax)! |
 | NOTE |
VelocitySafetyLimit and VOSPD should be greater than: 1000/ser.cycletime/VFac. In cases where vfac is set too low regular velocity values can trigger these. Issue 5267 |
