1 - GENERAL INFORMATION
1.1 - General
The
Powerdrive MD Smart equipment
is one (or more)
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
MD Smart equipment
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 MD Smart equipment
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.
1.2 - Designation of the equipment
Equipment may comprise several variable speed drives to
control several axis depending on the requirements defined
by the client in the specifications. These various variable
speed drives may be supplied by the electrical power
supply located upstream or by the DC bus delivered by the
equipment.
Equipment makes reference to a drawing number THxxxxx
established by the Electrical design service, in accordance
with a specification defined with the client.
This entire plan is sent to the client for validation before
production.
The drawings THxxxxx contain:
- Cover page
- Sheet list
- Wiring rules
- Electrical drawings
- Layout
- Front view of the cabinet with the various dimensions
- Bottom view for fixing to the floor
- Various terminal block connection diagrams
- Parts list giving details of the equipment.
The equipment used is
EC
compliant (compliant with EMC
2014/30/EC and Low Voltage 2014/35/EU Directives).
Equipment made in accordance with specifications and for
the organisation’s use are marked
EC
in accordance with the
LV Directive and EMC compliant.
The cross-section of the supply PE is calculated in
accordance with standard NFC 15-100 (equivalent to IEC
364).
Nameplate
I(A) = maximum input current for 400 V supply, in normal duty.
If there are several variable speed drives, I(A) is equal to the
sum of the currents for all of the variable speed drives.
OEF No. = ALICE order number
TH No. = electrical drawing number
The nameplate is located on the outside of the cabinet, at the
top right-hand side.
