FUNCTION C
O
DES
Note that, operating the inverter under the condition that the DC fan is locked for long time may shorten the life of
electrolytic capacitors on the PCBs due to local high temperature inside the inverter. Be sure to check with the
LIFE
signal
etc., and replace the broken fan as soon as possible.
Braking transistor error detection (Bit 6)
dba
(40 HP or below)
Upon detection of a built-in braking transistor error, this feature stops the inverter and displays an alarm
dba
. Set data of
this bit to "0" when the inverter does not use a braking transistor and there is no need of entering an alarm state.
Switch IP20/IP40 enclosure (Bit 7) (for basic type of inverters only)
Mounting an IP40 option to inverters of 40 HP or below enables them to conform to IP40. In such a case, switch Bit 7 to "1"
for the protection coordination.
For details, refer to the instruction manual of the IP40 option.
To set data of function code H98, assign the setting of each function to each bit and then convert the 8-bit binary to the
decimal number.
Refer to the assignment of each function to each bit and a conversion example below.
