W Description
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
RES Number of bits for fine resolution Gn_XIST1 (cyclic
actual encoder value)
RES Number of bits for fine resolution Gn_XIST2 (abso-
lute value of the encoder)
RES Number of differentiable encoder revolutions for a
multi-turn absolute value encoder
(For a single-turn absolute value encoder = 1;
for an incremental encoder = 0)
RES Load distance per revolution of an externally mount-
ed encoder
RES Homing mode
0: Homing mark only
1: Homing mark and proximity switch
2: Digital input
DIR Side of the digital input for passive homing:
FALSE: Negative side
TRUE: Positive side
DIR Homing direction / homing mark approach direction
0: Current homing direction
1: Positive homing direction
2: Negative homing direction
RON Byte number of the digital input
RON Bit number of the digital input
