frequency.
2 : Output Frequency Lower Limit
The output frequency lower limit can be adjusted by the analog input value.
3 : Auxiliary Frequency Command
Sets the auxiliary frequency command 1 when multi-step speed operation is selected. Refer to
L1-00~L1-16 on page 108 ？
4 : Output Voltage Bias
Voltage bias increases the output voltage of the V/F characteristics as a percentage of 200V or
400V depending on the power supply. This function is only available in the V/F Control
method.
5 : Acc./Dec. Time Gain (Decrease Only)
Adjusts the gain for acc./ dec. time assigned to C1-00 to C1-07.
When the acceleration time is assigned to C1-00, the drive acceleration time is calculated
below.
Acc. Time = C1-00 Acc. time × Acc./dec. time gain

6 : DC Braking (DB) Current
Adjusts the DC braking current by the analog input value.
When 10 V voltage or 20 mA current is input, the braking current will be 100% of the drive
rated output current. The actual DC braking current is determined by the analog input value or
the b2-01 value whichever is smaller.
