This chapter describes the technical specifications (electrical and mechanical)
of the CFW-09 inverter series.
Operating voltage range:
220-230 V, 380-480 V and 660-690 V models: -15 % to +10 %.
500-600 V models up to 32 A: -15 % of rated input voltage up to 690 V.
500-600 V models higher or equal to 44A:
- 500 V = -15 % to +15 %;
- 525 V = -15 % to +15 %;
- 550 V = -15 % to +20 %;
- 575 V = -15 % to +15 %;
- 600 V = -15 % to +10 %.
500-690 V models:
- 500 V = -15 % to +15 %;
- 525 V = -15 % to +15 %;
- 550 V = -15 % to +20 %;
- 575 V = -15 % to +15 %;
- 600 V = -15 % to +10 %;
- 660 V = -15 % to +10 %

When a line voltage higher than 600 V (rated value) supplies the 500-690 V
models, it is necessary to derate the output current as stated in item 9.1.5.
NOTE!
For models that have rated voltage selection jumper (as described in item
3.2.3) the rated input voltage is defined by its position.
In all models, P296 parameter shall be set to the rated input voltage.
When inputvoltage is lower than motor rated voltagethe motor power will be
reduced.
Other AC input specifications:
Frequency: 50/60 Hz (± 2 Hz).
Phase Unbalance

3 % of rated phase to phase input voltage.
OvervoltageCategoryIII (EN61010/UL508C).
Transient voltages according to CategoryIII.
Minimum line impedance:
1 % voltage drop for models with rated current up to 130A/220-230 V, up to
142A/380-480 V and up to 32 A/500-600 V.
2 % voltage drop for 380-480 V models with rated current 180A and above.
500-600 V modelswithcurrent higher or equalto 44A/500-600 V and all500-
690Vand660-690Vmodels do notrequireminimum lineimpedance,because
they have an internal DC Link inductance.
Refer to
item 8.7.1 guidelines.
Power-up
:
10 ON/OFF cycles per hour maximum (1 every 6 minutes).
