bit 3: Overow detection channel 2
0 on s.h. bit2 overow in ec.34
8 Off Overow detection not active e.g. linear - axes
7.11.11.4 Tachometer at channel 2
Ec.25: Nominal tacho speed
Default value 1500 rpm
Value range 0…16000 rpm
Nominal speed of tacho voltage
7.11.11.5 Evaluation intelligent interface
„Intelligent interface“ is a general term for all encoder interface types which contain their own micro-controller
for the encoder evaluation.
Parameters Ec.36...Ec.38 are only supported with these interface types.
Some encoder contain a so-called „electronic type plate“ if an intelligent interface is necessary for evaluation.
That means: the most important motor and encoder data can be stored in the encoder. Then this data can be
read out and accepted by the inverter at the start-up (for more details see "Ec.38 encoder 1r/w)
Ec.36 Encoder 1 r/w
The encoder is specied in this parameter:
