7.4 SHORT UPS MODULE
The Short UPS module is an accessory that provides autonomy of approximately 500 ms in case of failure of the
MVW3000 inverter auxiliary power supply. After the occurrence of the auxiliary power supply failure, the inverter
remains operational, without faults, during 500 ms.
The module is based on a low voltage frequency inverter, CFW10 and an external capacitor bank, which ensure
the energy supply to the power supplies during the specified period. A filter is added to the inverter output,
necessary because of the characteristic of the fed loads.
The Short UPS feeds the following loads:
PS1S power supply: responsible for feeding the gate drivers.
PS24 power supply: responsible for feeding the control.
General command: input circuit breaker supply and its undervoltage release.
7.4.1 CFW10 Inverter Parameterization
For the correct operation of the Short UPS module, the CFW10 inverter must be parameterized as shown below:
P100 = 1.0 (Acceleration time).
P101 = 0.5 (Deceleration time).
P121 = 57.4 (Output frequency).
P206 = 3 (Auto-reset time).
P222 = 0 (Remote speed reference).
P263 = 0 (DI1 Digital input).
P264 = 0 (DI2 Digital input).
P265 = 4 (DI3 Digital input).
P266 = 6 (DI4 Digital input).
P297 = 10 kHz (Switching frequency).
