98 EM-ABS-01 for ACU 03/12
8.4.3 Power supply
ia parameter Power supply 1186, you can choose the encoder power supply source.
Dependin
on the power demand of the encoder, you can connect an external power
supply to terminals X410A.1 and X410A.2 (see Chapter
5.3.3 “Power supply”). In this
case, parameter
Power supply 1186 must be set to “2 – Via X410A” or “6 – Via X410A,
Sense”.
The operation modes with meas. line “sense” (
Power supply 1186 = “5 – intern,
Sense” or “6 – Via X410A, Sense”) enable monitoring of the supply voltage of the en-
coder. In these settin
s, deviations will be compensated when the supply volta
e of the
encoder deviates from the set volta
e level. To that end, the volta
e is measured at the
end of the supply line (at encoder).
In operation modes 1 and 2, the voltage is controlled at the EM-ABS-01 module, powe
losses during energy transmission via the supply line will not be compensated.
The encoder can be powered as follows:
− via control terminals X410A.5 (5 … 12 VDC) and X410A.7 (GND) or
− via contacts X412.6 (V
Enc
) and X412.15 (0VL) of the female HD-Sub-D connector.
See chapters 5.3.2 “Control terminals” and 5.3.3 “Power supply”.
Caution!
Always set the Supply voltage 1187 first, then set Power supply 1186.
Otherwise, the encoder might be destroyed by high voltage levels.
Power supply 1186
0 - off
No power supply selected for the encoder. This setting is also used if the
encoder is connected directly to an external power supply.

Note:
Even if the encoder features a measurin
line “sense”, you can chose operation
mode 1 or 2.
