Note for Table 8.1 on page 8-2
- 1φ = single-phase power supply, 3 φ = three-phase power supply
(*) This model with the optional RFI filter has single-phase power supply only.
(1) Rated current in permanent duty under the following conditions:
- Recommended switching frequencies. For operation with switching frequencies of 10 kHz, it is necessary a derating of the rated output current
according to Table 8.2 on page
- Ambient temperature around the inverter: -10 °C to 50 °C (14 °F to 122 °F) for inverters with degree of protection IP2X/Nema1 and -10 ºC to 40 ºC
(14 °F to 104 °F) for inverters with degree of protection IP55. For operation of the inverter in environments with higher ambient temperatures around the
inverter, refer to Item 3.3.1 Installation on page
- Air relative humidity: 5 % to 95 % non-condensing.
- Altitude: 1000 m (3.300 ft); above 1000 m (3.300 ft) up to 4000 m (13.200 ft), output current derating of 1 % for each 100 m (330 ft) above 1000 m
(3.300 ft).
- From 2000 m (6.600 ft) to 4000 m (13.200 ft) - maximum voltage (240 V for models 220...240 V and 480 V for models 380...480 V) derating of
1.1 % for each 100 m (330 ft) above 2000 m (6.600 ft).
- Note that the derating specified in the items above also apply to the dynamic braking IGBT (column effective braking current (I
page 3-22).
- Environment with pollution degree 2 (as per EN50178 and UL 508C).
(2) Table 8.1 on page 8-2
ND and HD are presented in
(3) The switching frequency may be automatically reduced to 2.5 kHz, depending on the operating conditions (ambient temperature around the inverter,
output current, etc.) - if P0350 = 0 or 1.
(4) The motor outputs are only reference values for WEG 4-pole motors of 220 V or 440 V. The correct sizing of the VSD must be done according to the
rated current of the motors used.
(5) On the models with single-phase or three-phase power supply, the input current is presented for both cases. The input current for single-phase power
supply is presented first.
(6) The specified losses are valid for the nominal operating conditions, that is, for the rated output current and switching frequency. Exception: the values contained in
Table 8.2 on page 8-3
(7) The dissipated power for flange mounting corresponds to the total losses of the inverter minus the losses on the power modules (IGBT and rectifier).
(8) For the inverter to be supplied with such optional item, it is necessary to specify it in the inverter smart code - exception:
The RFI filter is built-in on models CFW110006S2OFA and CFW110007S2OFA. For further details, refer to
(9) It is not possible to have simultaneously the optional items Nema1 and Safety Stop function on CFW11 inverters of frame size A.
(10) - Ambient temperature around the inverter: -10 to 40 ºC (14 °F to 104 °F).
- Air relative humidity: 5 % to 95 % non-condensing.
- Altitude: 1000 m (3.300 ft); above 1000 m (3.300 ft) up to 4000 m (13.200 ft), output current derating of 1% for each 100 m (330 ft) above 1000 m (3.300 ft).
- Environment with pollution degree 2 (as per EN50178 and UL 508C).
