Parameter settings for a motor with
encoder
 Parameter for the encoder (Pr.359, Pr.369, Pr.851, Pr.852)
• Set the encoder specifications.
• The following table shows parameters to be set according to the vector control compatible option to be used.
 Parameter settings for the motor under vector control
• Values in indicate initial values.

0
Set when using a motor for which forward
rotation (encoder) is clockwise (CW) viewed
from the shaft Set for the operation at 120 Hz or
less.
100
Set for the operation at a
frequency higher than 120 Hz.
1
Set when using a motor for which forward
rotation (encoder) is counterclockwise (CCW)
viewed from the shaft Set for the operation at 120 Hz or
less.
101
Set for the operation at a
frequency higher than 120 Hz.
369
C140 851
C240 Number of
encoder pulses
1024 0 to 4096
Set the number of encoder pulses output.
Set the number of pulses before it is multiplied by 4.
The above parameters can be set when a vector control compatible option is mounted.
