0x1E8 - Max. velocity
This register sets the maximum allowed instant velocity.
By default, this register limits velocity set-points injected to the velocity control loops above the max velocity level. However if the velocity loop is not enabled it might work as a fault: if the measured velocity is higher than this value the drive triggers a velocity out of limits fault reaction.
The limit is active if at least the velocity loop is enabled. Therefore it works for a velocity and position modes, but it is inactive in current and voltage modes.
On the other hand, the fault is active if velocity loop is disabled. Therefore it is active only in current and voltage modes.
