Control of I component tracking for slave drive

made to follow such that M(set, ncontr.) = M(set, limit),
the speed setpoint is set to the actual speed value

Setting period of speed controller integrator [SW 1.9 and later]
After a positive edge at the binector set in P695, the integrator of the speed
controller is set to the instantaneous value of the connector set in P631.
If a time of > 0 is set on P230, this setting operation is not performed just
once, but the speed controller integrator is set continually to the setting
value for the parameterized time period.

Specifying the dynamic response of the speed control loop
[SW 2.0 and later]
The parameter value is used as the optimization criterion for the speed
control loop.
Note:
Changes to this value do not take effect until the speed controller
optimization run (P051 = 26, see Section 7.5) has been executed.
Setting instructions:
- For drives, for example, with gear backlash, optimization should be
started with low dynamic response values (from 10%).
- For drives with top synchronism and dynamic response requirements,
values up to 100% should be used.

Filtering of line frequency correction (field)
The internal line synchronization for the field gating pulses derived from the
field mains infeed terminals is filtered with this time constant. In operation
on "weak" power supplies with unstable frequencies, for example, on a
diesel-driven generator (isolated operation), the filter time constant must be
set lower than for operation on "constant V/Hz" systems in order to achieve
a higher frequency correction speed.
Using the units position, the line synchronization function can be altered
additionally
as follows:
When the parameter is set to an uneven
number, the measured line zero
crossings for line synchronization are subjected to an extra "filter", may
improve performance in the case of difficulties with brief mains interruptions
(e.g. power supply via sliding current collectors), but may only be set for
constant V/Hz power supplies (not for weak isolated supply systems).
