NK280B Parameter Reference
Parameter Name Description
Pn212 Number of Encoder Output Pulses -
Table 5: Wise Driver Parameters Related with Auto Adjustment
Parameter Name Description
Pr000 Rotational Direction Setup It is for setting rotation direction for motor.
• 0000: for forward commands, the motor
rotates towards CW.
• 0001: for forward commands, the motor
rotates towards CCW.
Pr008 Command Pulse Counts per One Motor
revolution
Its value is equal to divide screw-pitch by
pulse equivalent.
Pr009 1st Numerator of Electronic Gear
Pr010 1st Denominator of Electronic Gear
It is for ensuring control system parameters
Electronic Gear Ratio (Numerator) and
Electronic Gear Ratio (Denominator) are
consistent with the same driver parameters.
Pr011 Output Pulse Counts per One Motor
Revolution
Its value is equal to divide PG frequency
dividing ratio(X4) by 4.
Pr015 Absolute Encoder Setup It is for ensuring control system parameter
11001 Encoder Type is consistent with the
driver parameter.
• 0: used as absolute encoder.
• 1: used as incremental encoder.
• 2: used as absolute encoder and ignoring
count overflow of multiple rotations.
• 3: set by manufacturer.
• 4: set by manufacturer.
Parameters for Encoder
If you enable the encoder function, you need to set the parameters.
Use the encoder feedback function to detect or feed back linear movement distance of screw or
angular displacement of the servo motor.
Process of returning to the machine origin and tool calibration are diffferent acccording to the
usage of encoder feedback function.
You need to check nameplate of the encoder used for the servo motor for type information or
digit information.
