Electrical data
If Field weakening is needed, the minimum field current of the motor at top speed must be higher
than 0.3 A.
Electronic power supply
X3 is connected to a switch mode power supply with mains of 230 V
AC
or 115 V
AC
.
The power supply unit provides the galvanic isolated DC voltages 30 V, 15 V, 5 V and -15 V for the
control electronics.
In addition the power supply generates galvanically isolated 5 V for the serial communication drivers.
The voltages can be measured at following terminals:
Power part
AC input voltage 110 V -15 % ... 500 V +10 %; single-phase
AC input current < DC output current
Frequency Same as DCS module
AC isolation voltage 690 V
Line reactor (L1) 160 H; 45 ... 65 Hz (inside)
DC output current
50 A
0.3 A ... 50 A
DC output current
60 A
0.3 A ... 60 A; forced cooling (2 x fan)
Power loss at I
F rated
<180 W (at rated current)
Load condition Always L/R > 100 ms (saturation)
X2 Serial communication
