P081
*
EMF-dependent field weakening
0 No field-weakening operation as a function of speed or EMF
(100% of rated motor field current is applied constantly as the
internal field current setpoint).
1 Field-weakening operation by internal closed-loop EMF control
to ensure that in field-weakening operation, i.e. at speeds above
the motor rated speed (="field-weakening activation limit
speed”), the motor EMF is maintained constantly at the setpoint
EMF
set
(K0289) = P101 – P100 * P110 (field current setpoint is
the product of the EMF controller output and the precontrol
component determined by the actual speed according to the
field characteristic).
NOTE
When P081=1, a valid field characteristic must be available (P117=1),
otherwise the optimization run for field weakening (P051=27) must be
executed.

Operating mode for field
0 Internal field is not used (e.g. for permanent-field motors), 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.
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.
Note:
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.

Selection of actual speed value
0 Actual speed value is not yet selected (fixed value 0%)
1 Actual speed value supplied by "Main actual value” channel
(K0013) (terminals XT.103, XT.104)
2 Actual speed value supplied by "Actual speed from pulse
encoder” channel (K0040)
3 Actual speed value supplied by "Actual EMF" channel (K0287),
but weighted with P115 (operation without tacho)
4 Actual speed value is wired up freely (selected in P609)

Selection of closed-loop speed / current or torque control

2 Operation under closed-loop current / torque control (the
setpoint supplied by the ramp-function generator output is input
as a current or torque setpoint (speed controller is bypassed)

P085 Wait period after cancellation of inching command
After an inching command has been cancelled, the drive dwells in operating
state o1.3 for the time period set in this parameter with the controllers
disabled, but the line contactor closed. This wait period does not
commence until n<n
min
(P370, P371) is reached. If a new inching
command is input within this period, then the drive switches to the next
operating state (o1.2 or lower). However, if the time runs out without a new
inching command being entered, then the line contactor drops out and the
drive switches to operating state o7 (see also Section 9).
