7.4.3.6 Velocity Limit
In analog torque mode, if no limit is set on the motor’s velocity, and the load inertia is small, the motor’s velocity will be very fast, and
could damage the machinery. Therefore, it is very important to set a velocity limit.
The velocity limit for torque mode can be set via analog input 1 (ANA1).
