Input address for the PROFIdrive frame
Output address for the PROFIdrive frame
Telegram UDINT - 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)
