For a rotational encoder working with current signals, the current/ voltage terminal ACC/DSUB-ENC-4-IU
can be used.
It is possible to power the sensor from the ENC-4 module. The pertinent specifications are:
max. supply current: 320 mA
typ. encoder with 11
Heidenhain ROD 456, current c: max. 85 mA per (2-signal) encoder
5.1.2 Analog outputs
The analog outputs DAC 01 to 04 provide 4 analog output channels to be used as dynamic control and
actuator signals. The outputs can be defined as the results of calculations performed by imc Online
FAMOS on data from combinations of measurement channels.
The pin configuration of the corresponding DSUB-15:

Highlights
·
±10 V level at max. ±10 mA driver capability and 250 Ω load
·
ensured startup level 0 V without undefined transient states
·
short-circuit protected against ground.
