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.

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.
