W Description
RES Encoder type
0: Incremental
1: Absolute
2: Cyclically absolute
RES Inversion of the actual value
FALSE: no
TRUE: yes
RES Encoder system
0: Linear encoder
1: Rotary encoder
RES Mounting type of the encoder
0: Incremental

RON Input address for the PROFIdrive frame
RON Output address for the PROFIdrive frame
RON PROFIdrive frame of the encoder
3: Actual values via drive frame
(NSET (32 bit), NACT (32 bit), actual encoder value,
signs of life)
5: Actual values from drive frame
(NSETP (32-bit), NACT (32-bit), actual encoder
value, sign-of-life, DSC)
81: Actual values via your own encoder telegram
(actual encoder value, signs of life)
83: Actual values via your own encoder telegram
(NACT (32 bit), actual encoder value, signs of life)
For the technology object of external encoders, only
frames 81 and 83 are valid.
(NSET - setpoint speed, NACT - actual speed value)
RES Resolution of a linear encoder (offset between two
encoder pulses)
RES Increments per rotary encoder revolution
