Due to these changing needs, the people responsible for designing and manufacturing new automation
equipment are being forced to deal with servos and are facing a myriad of difficult choices and questions.
Some of these questions will be discussed. A discussion of a basic servo follows this discussion.
Need a Velocity Loop?
One of the first questions the designer usually asks is: Do I need a velocity feedback loop? Usually the
answer is yes because it provides additional stiffness. The velocity loop is inside the position loop as is
shown in Figure 1.
The bandwidth of the velocity loop is an order of magnitude higher than the position loop that is being
discussed, so the position loop basically sees the velocity command VC equaling the velocity feedback VF
Servo Basics for the Layman Page 2 for frequencies within its bandwidth. This is important so that the velocity loop does not change the gain, and thereby the stability of the position loop. When VF is not exactly equal to VC, there is an additional gain factor A' to help with forcing. This is what provides the higher stiffness.
In the real world, a position loop can sit with a constant error because that error is not so large that it can
develop enough motor torque to overcome static friction. When the velocity loop is added, this error is
multiplied by the additional factor of A' until friction is broken and motion takes place so that VF can
once again equal VC. A simple test can be made to show the impact of a velocity loop. If one grabs the
shaft of a motor without a velocity loop, he will find that he can turn it and hold it out of position
indefinitely. If the velocity loop is activated, he will find that he can initially turn it the same amount, but
it will immediately fight his action and turn the shaft back into position. This is stiffness and it results in
better accuracy.
There is no need to worry about damage to your products during transport. We know how important it is to deliver a product safely. Thanks to our long-term cooperation with UPS, we have developed innovative ways of securing devices for transport.
We use three types of packaging for sending devices:
WOODEN CRATE DESIGNED FOR SERVO MOTORS FOR MAXIMUM SAFETY. BY SECURELY FIXING OUR PRODUCTS, WE ENSURE THAT THEY REACH OUR CUSTOMERS IN PERFECT CONDITION.
INSTAPAK - SPECIALLY SELECTED POLYURETHANE FILLER ADAPTS TO THE SHAPE OF THE DEVICE FOR MAXIMUM PROTECTION
DEDICATED PALLET DEVICES WITH NON-STANDARD DIMENIONS OR WEIGHT, ARE TRANSPORTED ON DEDICATED PALLETS, ALLOWING FOR THE SAFE SHIPPING OF LARGE EQUIPMENT.
