Installation and Connection
NOTE!
Make sure the CFW-11M inverter has the 2.0x software version or above. For more details, refer to
the "CFW-11M user manual" and the "CFW-11 programming manual".
The examples of
inputs are set to "Without External Rectifier Fault" (P0832 = 6) and "Without External Rectifier Overtemperature"
(P0833 = 4) respectively. On both examples, the CFW-11M will show F414 ("External Rectifier Fault") if DIM1
input (and therefore the RL1 output relay - "UCD1_OK / UDC2_OK" - of the CIR11) opens when the DC
bus voltage is higher than the undervoltage level and the CFW-11M PWM is enabled; or it will display F412
("External Rectifier Overtemperature") if DIM2 input (and therefore the output relay RL3 - "Without Temperature
Fault" - of CIR11) opens.
Figure 3.24 on page 3-22
(P0832 = 5) and "Without External Rectifier Overtemperature Fault" (P0833 = 4), respectively. In this case,
the CFW-11M will display A415 ("External Rectifier High Temperature" alarm) if the DIM1 (and therefore the
RL2 relay output - "Without Temperature Alarm" - of CIR11) opens, and it will display F412 ("External Rectifier
3
Overtemperature") if the DIM2 input (and therefore the RL3 relay output - "Without Temperature Fault" - of
CIR11) opens.
