1 - GENERAL INFORMATION
1.1 - General
the
POWERDRIVE MD2CS
is a variable speed drive with
very high performance levels that can be used to control:
- 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 MD2CS
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
POWERDRIVE MD2CS
is compatible with
use in all 4 quadrants of the torque/speed plane with the
braking module option .
POWERDRIVE MD2CS drives are IP00 protection
products, designed to be installed in a cabinet with
limit access to only habilited and trained personnel.
A
line reactor and a surge protection module must be
connected to the drive.

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

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.
