1:10V
STOPPED
Allows the user to select the correct supply voltage for the pulse encoder.
Encoder Type
1875
Same as PNO 1874
0 0:SIN COS STOPPED
Allows the user to select the encoder type connected.
SINCOS type is incremental encoder type. Associated to a PMAC motor, setting up the position offset needs to be done at each drive
power on or after a trip related to the encoder.
Encoder Lines
1876
Same as PNO 1874
512 1 to 1048576 STOPPED
Allows the user to select the correct number of lines per one encoder revolution.
Encoder Invert
1877
Same as PNO 1874
FALSE
STOPPED
Reverses the encoder direction if set to TRUE. The encoder direction needs to be correct if encoder feedback is used to control the
motor in vector mode. The autotune identifies whether the parameter is in the correct state required to control the motor, and changes
it if necessary ( for Induction motor only ). It is possible to do this manually, by attempting to run the motor, and changing the
parameter if necessary until the motor is controlled correctly.
Encoder Speed
1892
Same as PNO 1878
x. RPM NEVER
The encoder mechanical speed measured by the encoder, in revolutions per minute.
