(10) Frequency Command Characteristics Selection
(Sn-10)
Sn-10 = 0 : Forward characteristics of frequency command
(0~10V or 4~20mA /0~100%)
= 1 : Reverse characteristics of frequency command
(10~0V or 20~4mA /100~0%)
(11) Scan Time at Input Terminal
(Sn-11)
•
Setting of scan frequency of input terminal (Forward/Reverse, multi-function
input)
Sn-11 = 0 : Scan input terminals every 5ms.
= 1 : Scan input terminals every 10ms.
(12) Overtorque Detection Selection
(Sn-12)
•
When overtorque detection is enabled, be sure to set the value of the overtorque
detection level (Cn-32) and the overtorque detection time (Cn-33). An overtorque
condition us detected when the current exceeds the overtorque detection level for
longer than the overtorque detection time.

(13) Output Voltage Limitation Selection (Sn-13)
•
In low speed region, if the output voltage from V/f pattern is too high, the inverter
will be driven into fault status. As a result, the user can use this option to set the
upper bound limit of output voltage.
