Technical specifications
1)
The data for the rated input current and the power data in hp and kW are
approximate values only; these have been calculated for operation with
synchronous motors for a power factor cos phi =1 and a motor efficiency of
96%. The calculation is based on the rated output current. The rated input
current also depends on the line power factor, for which a typical value of 1
was assumed.
The hp data are based on the NEC and CEC guidelines for the North
American market. The kW values are specified in multiples of 500. Both
approximate values need to be adapted to the motor which is actually
used.
2)
The underlying circuits are based on a drive line-up in which the drives
operate both as motor and generator. Energy is exchanged via the DC link.
The specified power corresponds to the maximum infeed power. The effec-
tive total power of the Motor Modules (taking into account the power flow
direction) may not exceed this infeed power.
3)
Approx. 5 % of the power loss is dissipated in the room.
4)
Without cooling system
5)
The typical current drawn (rms value; cos
ϕ
typ.
= 0,6) of the supply for the
converter open-loop/closed-loop control is specified. The separate sup-
plies for the socket outlets/light or switched auxiliary power feeders
(options
N35 to N38
) have not been taken into account. Values for the typ-
ical current drawn for special configurations (e.g. for dimensioning an
upstream UPS) are available on request.
When using options
L48
(make-proof grounding switch at the converter
input),
L49
(make-proof grounding switch at the converter output) or
L51
(disconnector at the converter output), it should further be taken into
account that for switching operations, additional peak values of up to 10 A
can occur for each make-proof grounding switch or disconnector. This
corresponds to the starting current of a motor used to operate a switch,
which decays from approx. 10 A to approx. 2 A in 200 ms. A switching
operation takes a total time of approx. 2 s. All optionally used make-proof
grounding switches or disconnectors are controlled via the manually-
actuated make-proof grounding switch for the converter DC link (standard)
and therefore switch simultaneously!
6)
Data refer to a sub-system; for details about the number of sub-systems to
be connected on the line or motor side,
see Circuit versions, Pages 5/4
and 5/5
.
7)
The maximum permissible cable lengths must be observed (
see Power
cables, Page 9/13
).
8)
The specified dimensions and weights include doors, panels and cooling
unit, however no options.
9)
Depending on the pressure equalization tank, the cooling unit can have a
maximum cabinet height of 2790 mm.
