2. Specifications:
2.1 Electrical Data
Power Supply Voltage
+9 to +70 VDC
(Residual ripple <5 %)
(The lower limit is monitored by
integrated undervoltage trip)
WARNING: Do not exceed 70V.
Overvoltage will damage the drive.
Auxiliary Voltage Input
+5 to +30 VDC
Supply voltage for the /Error output.
(Refer chapter 7.2)
Nominal Current 9 / 18 A (model dependent)
Peak Current 18 / 36 A (model dependent)
Maximum Power (only achievable with
additional heatsink & proper mounting,
see accessories.)
630 / 1260 W (model dependent)
Switching Frequency 50 kHz
Efficiency 97 %
Induction Specification & caution for low
inductance motors Optional choke modules are often an
economical solution for low inductance or
other motors, if an overheating situation
occurs in regular intervals. Contact
factory service for details.
Power connector The diameter must be suited for the
connecting wires of the current load. The
recommendation is 1,5 mm2(AWG16),
the minimum is 0,13 mm2(AWG28).
Maximum wire diameter with respect to
the plug contact is 2,5 mm2 (AWG14).
Strip the wire insulation of the cables on
a length of 10mm. For stranded wire, use
end sleeves with the corresponding
length. Wire ends have to be inserted
into the contact, until they reach the stop.
Signal terminals For the cabling of the RJ45 plugs, we
recommended shielded CAT5 cables.
The cables are available in different
colours and lengths in the system
accessories.
