Servo control upgrades are used when positioning

and accuracy are required. If you need to follow

 a product or a conveying system closely then a

servo upgrade will be what you want. 

When you need controlled braking, ramping up of a motor or harsh

 duty starts and stops, the servo motor best fits these applications. 

Or if you need high speeds and more power

in a small package motor, servo controls are the way to go.
