Principle of the „IRC Detuning“ function at active choice „torque restriction“.
RESET PWM is generated when the maximal limit of frequency difference „Maximal IRC1,2
difference“ (ID 1085) is exceeded, if the choice „reset PWM“ is active in the parameter „IRC1,2
Detuning“ (ID 1082). “RESET PWM” expires after decrease under „Minimal IRC1,2 difference“ (ID
1084).
Principle of the „IRC Detuning“ function at active choice „reset PWM“
By adjustable filter „Filter dIRC1,2“ (ID 1083), short pulses of IRC can be filtered, quantization
noise is damped and dynamics od torque change can be adjusted.
The impact of IRC detuning to the maximal torque and to the RESET PWM too can be combined
with simultaneous activation of the both options.
8.15 Using the parameter set switching for a special behavior of converter
functions
UNIFREM frequency converters contain 4 user parameter sets, which can be switched and edited
independently in the converter. Set switch period is currently less than 50ms. If the parameter
settings are not different for parameters which block the change on-the-run (like Output phase
sequence), it is possible to switch the sets during operation. The source of the set switch can be
configured to any converter signal. This allows to solve special functions conditioned by changing
the parameters, which individual functional blocks of the converter when using single set do not
allow.
