Displaying running status
To display the running status in hexadecimal format, each state has been assigned to bit 0 to 15 as
listed in Table 3.7. Table 3.8 shows the relationship between each of the status assignments and the
LED monitor display. Table 3.9 gives the conversion table from 4-bit binary to hexadecimal.

Bit Notation Content Bit Notation Content
15 BUSY 1 when function code data is being
written.
7 VL 1 under voltage limiting control.
14 Always 0. 6 TL Always 0.
13
WR
Always 0. 5 NUV 1 when the DC link circuit voltage
is higher than the undervoltage
level.
12 RL 1 when communication is effective
(when run commands and set
frequencies commands are issued
via communications). 4 BRK Always 0.
11 ALM 1 when an alarm has occurred. 3 INT 1 when the inverter output is
stopped.
10 DEC 1 during deceleration. 2 EXT 1 during DC braking.
9 ACC 1 during acceleration. 1 REV 1 during running in the reverse
direction.
8 IL 1 under current limiting control. 0 FWD 1 during running in the forward
direction.
