1.2.2 Applicable incremental rotary encoder
- 32 -
An incremental rotary encoder to be used for the FANUC
SYNCHRONOUS BUILT-IN SERVO MOTOR Dis series must
satisfy the following specifications:
- The output from the rotary encoder is an analog signal at 1 Vp-p.
- A reference mark signal (Z-phase signal or another signal) is
output from one device or the rotary encoder is distance coded.
If reference mark signals are output from two or more devices, an
alarm may occur when the same signal is detected for the second time.
To rotate the motor infinitely, the encoder should output the
waveforms of binary count. If not, the motor cannot rotate infinitely.
Example:
Encoder output 2
n
λ/rev. Rotate without limitation
・・・・・・
・・・・
Encoder not output 2
n
λ/rev. Rotate with limitation
Contact an encoder manufacturers to get more detail information
about the encoders.
NOTE
Rotary encoder manufacturers are responsible for the
specifications, performance, guarantee, and other
items of their rotary encoders.
For details, contact the relevant manufacturer.
