Lenze g500-B - Absolute Value Encoder

Absolute value encoder
Absolute value encoders can detect the speed, the rotor posion, and the machine posion
with a v
ery high resoluon. They are used for the posioning of dynamic applicaons and do
not require homing.
The digital absolute value encoder AM20-8V-D for one-cable technology is
possible with the following motors:
m850-S120/S3960
m850-S120/M3960
m850-S120/L3960
m850-S140/S3240
m850-S140/M3240
m850-S190/S3000
