C241 Encoder rotation
direction
1
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 parameters above can be set when a vector control compatible option is installed.
