Description
P082
Operating mode for field
*
No field
(G166)
0
No field is used (e.g. in the case of permanent-field motors). The
field gating pulses are disabled. Unlike all other cases, the motor
flux (K0290) is not calculated according to the field characteristic
(P120 to P139) as a function of the actual field current (K0265),
but set to the value for 100% rated flux.
Internal field power module
1
The field is switched with the line contactor - this setting must be
selected if the mains supplies for the field and armature power
sections are connected or disconnected simultaneously (field
gating pulses are enabled/disabled at the same time as the line
contactor is closed/opened, the field current decays with the
field time constant).
2
Automatic injection of standstill field set in P257 after expiry of a
time period set in P258, after converter has reached operating
state o7 or higher.
3
Field ACTIVE continuously.
4
The field is switched with the "Auxiliaries ON" (B0251) signal
External field power module (40.00A field)
11
Board C98043-A7044 (40A field power module) is inserted at
connector X102 on board C98043-A7002 or C98043-A7003.
The field is controlled as described in para. 1.
12
As described in para. 11, but
the field is controlled as described in para. 2.
13
As described in para. 11, but
the field is controlled as described in para. 3.
14
As described in para. 11, but
the field is controlled as described in para. 4.
External field device
21
An external field device is used. The setpoint for the external
field device is supplied via connector K0268 (e.g. via an analog
output or the peer-to-peer interface).
The rated DC current of the external field device is set in
parameter U838. This value is also displayed in parameter
r073.001. P076.002 is inoperative.
If the external field device supplies an actual field current signal,
then this can be fed in at P612. If not, then P263 should be set
to 1 or 2.
If the external field device supplies an "I field < I field min"
signal, then this can be fed in at P265.
The field is controlled as described in para. 1.
22
As described in para. 21, but
the field is controlled as described in para. 2.
23
As described in para. 21, but
the field is controlled as described in para. 3.
24
As described in para. 21, but
the field is controlled as described in para. 4.
NOTICE
Even though changes to the parameter value from > 0 to = 0 are
accepted in operating states of ≥ o1.0, they do not take effect until the
converter reaches an operating state of ≥ o7.0.
