1) This is maximum load when only one supply voltage is used; when 2 or 3 supply voltages are
used simultaneously the load must be reduced accordingly. The following must be observed:
load24V + load8V + load5V ≤ 6W and load8V + load5V ≤ 2W.
2) 8 V is only available at terminal block X55.

Reference index Bit 0 Reference position index number bit 0 (least signifi-
(LSB) cant bit). Not used in fieldbus mode.
Reference index Bit 1 Reference position index number bit 1. Not used in
fieldbus mode.
GND Ground for 24V is normally bridged with Terminal 39,
but can be set to "OFF" by means of Switch SW 4 on
the control card.
Reset / ENABLE (error Errors are cleared on the rising edge (must be "0"
clear) min. 1 ms. to guarantee edge detection). Not used in
fieldbus mode. To enable operation, this input must
be maintained at "1" in either digital control mode or
fieldbus control mode.
Reference index Bit 4 Reference position index number bit 4 (most signifi-
(MSB) cant bit). Not used in fieldbus mode. Not used in FC
301.
Reference index Bit 3 Reference position index number bit 3. Not used in
fieldbus mode.
Reference index Bit 2 Reference position index number bit 2. Not used in
fieldbus mode.
