Description (100% output corresponds to 10 V level)
07
DC injection braking
DC Brakin current
According to analog input voltage (0-10V), change the
level of DC injection current (0-100
％
).
(inverter rated current=100%, the setting of DC injection
current Cn-15 is disabled )
08
Stall prevention level
during running
Run Still Level
According to analog input voltage (1.5V-10V), change the
level of stall prevention during running (30%-200%)
(inverter rated current=100%, the setting Cn-26 is
disabled.)
09
PID control reference
input
PID Command
Multi-function analog input (terminal AUX) used as PID
control reference input (0-10V). Refer to App-1 PID
Application Note.
10
Frequency command
lower limit
Freq. Cmd. Low
Bound
Changes the frequency command lower-limit (0-100
％
)
value according to the then analog input voltage (0-10V)
(Max. output frequency (Cn-02) corresponds to the 100%
analog output. The actual lower-limit is determined by the
maximum value of Cn-19 and the value corresponding to
the multi-function analog input terminal).
11
Jump frequency setting4
Freq Jump 4
Sets the jump frequency 4, according to analog input
voltage (0-10V), while Cn-20 to Cn-23 can be used to set
the jump frequency 1-3 and their jump frequency width.
12
RS-485 communication
application
Comm. Control
The analog value of AUX 0 – 10V can be read through
serial communication (RS485). The scaling is
(0 -10V = 0 – 1024)

The AUX analog input can provide two groups of gain and bias; Sn-29 =1-3 and Sn-29=13-15. When
Sn-29=13-15, the adjustment of gain and bias is similar to the GA series. (See Fig. 9.2.3.17)
