1.8.2 DIAS-Drive Concept
•
1 and 3-axis amplifiers to reduce machine costs. 3-axis amplifiers have advantages
reducing components
•
Auto-range function to optimize the resolution of the actual current value of 10 A axes,
in various configurations.
•
Two different mounting options.
➢
On a mounting place in the control cabinet
➢
Through-hole technology
•
Broad input voltage range from 3 x 230 VAC
-10%
… 3 x 480 VAC
+10%
supplied from TN-
supply or TT-supply with grounded neutral point, with a maximum current of
symmetrical 5000 A
RMS
.
•
TT supplies without grounded neutral lines require additional measures.
•
Charging circuit for limiting the maximum load current at the power-up moment.
•
Fuse installed by user (phase failure is monitored by the amplifier)
•
1-phase operation is possible, e.g. for initial start-up
•
24 V auxiliary supply, galvanically isolated for independent power.
•
Separate 24 Volt connection to power the holding brakes.
•
Noise filter for the main, 24 V auxiliary and holding brake supplies, class A (industrial
use)
•
Housing with connection for the cable shielding
•
Protective functions against:
➢
Under or over voltage in the DC-link circuit.
➢
Several short circuit conditions
➢
Phase error in the main supply
➢
Brake resistance over heating
➢
Over temperature (heat sink, ambient and motor)
•
The overload protection is provided internally by the drive. The load current is limited to
100 % of peak output current. For the thermal protection of the motor the I
2
T regulation
is used.
