Control Units
3.1.5 Aux-function (An.30)
The A-servo has only one analog input, the Aux-function can be used also with other input values (e.g. PI con-
troller output, motorpoti).
3.1.6 Voltage input / external power supply
The supply of the control circuit through an external voltage source keeps the control in operational condition
even if the power stage is switched off. To prevent undefined conditions at external power supply the basic
procedure is to first switch on the power supply and after that the inverter.
3.2 Control circuit A-servo
3.2.1 Terminal strip X2A
Tightening torque 0.22…0.25 Nm (2 lb inches).
Use shielded/drilled cables
Lay shield on one side of the inverter onto earth
potential
No NPN control is possible at A-servo!

Supply of the driver circuit
This input must be supplied with an external voltage of 20…30 V DC
±0 % / 0.2 A (U
BR
max. 3.6 Vss). An error reset is executed when
switching off this voltage
18 Transistor Output 1 O1
