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.
Description
-
Description
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.
Its value is equal to divide screw-pitch by
pulse equivalent.
It is for ensuring control system parameters
Electronic Gear Ratio (Numerator) and
Electronic Gear Ratio (Denominator) are
consistent with the same driver parameters.
Its value is equal to divide PG frequency
dividing ratio(X4) by 4.
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.
