1 - GENERAL INFORMATION
1.1 - General
The
POWERDRIVE MD2R
is a variable speed drive with
active rectifier allowing to feed back the braking energy of
electrical machine to the mains (operation in the 4 quadrant
of the torque/speed map) and/or to limit the harmonic level of
the power line. (< 5% typique).
The high efficiency performance of the
POWERDRIVE MD2R
can drive :
- Induction motors without speed sensor (open loop mode
select
) for applications that do not need rated torque
control above 1/10
th
of the rated speed.
- Asynchronous or synchronous permanent magnet motors
with virtual speed feedback (flux vector mode with software
sensor function
) for applications that require rated torque
control from 1/20
th
of the rated speed.
Combined with the MDX-ENCODER option, the
POWERDRIVE MD2R
is a drive that can also be used to
control asynchronous or synchronous magnet machines for
applications that require very high dynamic performances,
torque control from zero speed or high speed accuracy
(closed loop vector mode with speed feedback
).
The
POWERDRIVE MD2R
allows also controlling the level of
the reactive current of the power line.
With IP54 protection (optional), installation is possible directly
on the machine itself in harsh environments.

Classification of
environmental
conditions
In accordance with IEC 60721-3-3:
•
Biological classification in accordance
with class 3B1
•
Classification as regards chemically
active substances in acc. with class 3C2
•
Classification as regards mechanically
active substances in acc. with class 3S2
Relative humidity
In accordance with IEC 60068-2-56
< 90% non condensing
Altitude
≤ 1000 m without derating
> 1000 m up to 4000 m maximum
(as required):
• Current derating of 1% per additional
100 m
E.g. for 1300 m, derate the Ico and Imax
currents by 3%
• Operating temperature derating of
0.6°C per 100 m
E.g. for 1300 m, the electrical
characteristics are maintained for an
ambient temperature of
[40°- (3 x 0.6°)] = 38.2°C.
