5.4 Details of Function Codes
5-152
Assignment of bulk alarm ALM (Function code data = 99)
This function outputs an ON signal when any of alarms is output.
Assignment of braking transistor broken DBAL (Function code data = 105)
When the braking transistor malfunction is detected, this function outputs the braking transistor broken
(alarm
dba
), and outputs an ON signal to DBAL simultaneously. To invalidate the detection of the braking
transistor broken, use the function code H98. (22 kW or lower for 200/400 V class series)
(
Function code H98)
A breakdown of the braking transistor could lead to a damage of the braking resistor or inverter’s
internal units. To detect the integrated braking transistor broken status and to prevent the
secondary damage, use DBAL to turn off the magnetic contactor at the input side of the inverter.
E30
Frequency Arrival Detection Width (Detection Width)
This function sets the operation level (detection range) of the Frequency (speed) arrival FAR and the
Frequency (speed) arrival 3 FAR3.

Output
Signal
Assigned Data Operating Condition 1 Operating Condition 2
FAR 1
This signal always turns off when
the run command is off or the
speed command is "0."
FAR3 72
Both signals turn on when the
difference between the output
frequency (speed detection
value) and the set frequency
(speed command) is within
the frequency arrival
detection range.
When the run command is off, the
speed command is taken as 0.
When the output frequency is within
0 +/- frequency arrival detection
range, an on signal is output.
- Data setting range: 0.0 to 10.0 (Hz)
The operation timings of each signal are as shown below.
