2052h Encoder Resolution

Function

Contains the physical resolution of the encoder that is used for commutation.

Object description

PDO mapping no
Allowed values
Preset value 00001000h
Firmware version FIR-v1426
Change history

Firmware version FIR-v1540: "Savable" entry changed from "no" to "yes, category: tuning".

Description

A negative value means that the encoder is driven in the opposite direction of the motor. This can be corrected by reversing the polarity of a motor winding.

Tip: The unit is "pulses per revolution" (ppr), which corresponds to four times the resolution in "counts per revolution" (cpr) (quadrature). This means that for an encoder with a resolution of, e.g., 1000 increments per revolution, the value in 2052h is 4000.
