11.12.3 GC Disturbance [G30]
This menu contain settings related GC-FRT functions
which includes UVRT, OVRT, UFRT, OFRT, AID. It also
provide settings related to open circuit detection and brake
resistor over-load protection. Other than that, normal
operation range for AFR/AFG can also be define in this
menu.
GC NormRange [G31]
Operating range (for supply voltage and frequency) for
normal continues operation of AFR/AFG unit can be
configured in this menu.
Umin [G311]
Menu for defining the minimum supply voltage required for
continues normal operation of AFR/AFG.
Umax [G312]
Menu for defining the maximum allowed supply voltage for
continues normal operation of AFR/AFG.
Fmin [G313]
Menu for defining the minimum supply frequency required
for continues normal operation of AFR/AFG.
Fmax [G314]
Menu for defining the maximum allowed supply frequency
for continues normal operation of AFR/AFG.
Umaxmax [G315]
Absolute maximum voltage that can be injected/supplied by
the AFR/AFG.
GC dU(FRT) [G32]
This menu contain parameters related to dynamic voltage
support during UVRT and OVRT.
dU Imax(P) [G321]
Maximum active current during FRT. Normalized to AFR/
AFG nominal currents.
dU Imax(Q) [G322]
Maximum reactive current during FRT. Normalized to
AFR/AFG nominal currents.
dU Uband [G323]
Voltage insensitivity dead-band.
Voltage steps within the insensitivity dead-band does not
activate dynamic voltage support.
