FWD : Running forward TL : Torque limiting RL : Communication selection
REV : Running in reverse (1: H30 = 2 or 3)
EXT : DC braking / pre-excitation IL : Current limiting
INT : Inverter shutdown ACC : Accelerating - (FRENIC-VG is always 0)
BRK : Braking DEC : Decelerating ERR : Function code access error
NUV : DC link voltage established ALM : Alarm relay BUSY : Writing function code
ERR is "0" when function code selecting (writing) and polling (reading) all took place normally. If a selecting or
polling operation was abnormal, ERR becomes "1"
*1
. The cause of the error can be checked in function code
M26 (the table below). When this bit is "1", remove the cause of the error as indicated in M26 and perform
selecting/polling. If all finish normally at this time, ERR and M26 automatically change to "0".
Value of M26 (HEX.) Write/read error
78 (4EH) Accessed unused function code
79 (4FH) Write to read-only function code
Write while running to function code that cannot be changed while
running
Write to function code that cannot be changed when FWD/REV is
ON
80 (50H) Out of range data write
*1 If multiple errors occur simultaneously, the M26 error cause will be shown in the following order of priority:
Selecting (2) > Selecting (1) > Polling (2) > Polling (1).
(For example, if both selecting (2) and polling (1) are errors, the cause of the selecting (2) error will be stored in M26.)
BUSY is "1" during data writing (processing). To successively write data, wait until this bit is "0" before writing
the next data. Data written while this bit is "1" will be disregarded.
