1 - GENERAL INFORMATION
1.1 - General
The
Powerdrive MD2S
is a variable speed drive with very
high performance levels that can be used to control:
- Induction motors without a speed sensor (open loop mode
select
) for applications that do not need rated torque
control above 1/10
th
of the rated speed.
- Induction motors 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 MD2S
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 performance of the
Powerdrive MD2S
is compatible
with use in all 4 quadrants of the torque/speed plane with the
braking module option incorporated.
With IP54 protection (optional), installation is possible directly
next to the machine in harsh environments.

Relative humidity
In accordance with IEC 60068-2-56
< 90% non condensing
Altitude
≤ 1,000 m without derating
> 1,000 m up to 4000 m maximum (as
required):
•
Current derating of 1% per
additional 100 m
E.g.: for 1,300 m, derate the Ico and
Imax currents by 3%
