Encoders for servo drives

Controlling systems for servo drives

require measuring systems that provide

feedback for the position and speed

controllers and for electronic commutation.

The properties of encoders have decisive

inﬂ uence on important motor qualities such

as:

• Positioning accuracy

• Speed stability

• Bandwidth, which determines drive

command-signal response and

disturbance rejection capability

• Power loss

• Size

• Noise emission

• Safety

Rotary encoder ( actual position value,

actual speed value,

commutation signal)

HEIDENHAIN offers the appropriate

solution for any of a wide range of

applications using both rotary and linear

motors:

• Incremental rotary encoders with and

without commutation tracks, absolute

rotary encoders

• Incremental and absolute angle

encoders

• Incremental and absolute linear

encoders

• Incremental modular encoders
