STOPPED 
 
Allows the user to select the correct supply voltage for the pulse encoder.

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

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.
