1 - GENERAL INFORMATION
1.1 - General
The
POwERDRIVE MD2SL
is a liquid-cooled variable speed
drive which combines a diode/thyristor rectifier and an IGBT
inverter. The high performances of
POwERDRIVE MD2SL
allow 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 MD2SL
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 MD2SL
is compatible
with use in all 4 quadrants of the torque/speed plane with the
braking module option.
With IP54 protection (optional). installation is possible directly
in the machine environnement.
