2. Specifications:
2.1 Electrical Data
Power Supply Voltage +11 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.
Nominal Current 10 A
Peak Current 20 A
Maximum Power (only achievable with
additional heatsink & proper mounting,
see accessories.)
700 W
Switching Frequency 49 kHz
Efficiency 95 %
Induction Specification & caution for low
inductance motors
Integrated choke 370 µH
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 terminals
The diameter must be suited for the
current load. The recommendation for
the drive is 1,5 mm
2
(AWG16). Maximum
wire diameter with respect to the terminal
is 2,5 mm
2
(AWG14) or 1,5 mm
2
(AWG16) for stranded wires. Strip the
wire insulation of the cables on a length
of maximal 8 mm. For stranded wire, use
end sleeves with the corresponding
length.
Signal terminals
The recommendation is 0,5 mm
2
(AWG21), the min. is 0,14 mm
2
(AWG26)
and the max. is 1,5 mm
2
(AWG16). Strip
the wire insulation of the cables on a
length of maximal 7 mm. For stranded
wire, use end sleeves with the
corresponding length.
