Setting 5: Accel/decel time gain
Adjusts the gain level for the acceleration and deceleration times set in parameters C1-01 through C1-08.
The acceleration time used by the drive is calculated by multiplying this gain level by C1-
× Accel/decel time gain = Drive accel/decel time

Setting 6: DC Injection Braking current
The current level used for DC Injection Braking. Set as a percentage of the maximum output current using.
When setting the bias by parameter, however, make the setting as a percentage of the motor rated current.
Note also that the DC injection braking current is limited by the motor rated current value.

Setting 7: Torque Detection level
Using this setting, the overtorque/undertorque detection level for Torque Detection Selection 1 (L6-01) can be set by an
analog input. The analog input will replace the level set for Torque Detection Level 1 (L6-02). An analog input of 100%
(10 V) will set a torque detection level equal to 100% drive rated current / motor rated torque. Adjust the analog input
gain if higher detection level settings are required. Refer to
Setting 8: Stall Prevention level
This setting allows an analog input signal to adjust the Stall Prevention level.
characteristics. The drive will use either the Stall Prevention level set in L3-06 or the level coming from the analog input
terminal that has been selected, whichever value is lower.

Setting 9: Output frequency lower limit level
The user can adjust the lower limit of the output frequency using an analog input signal.
Setting B: PID feedback
An input set for this function supplies the PID feedback value. This setting requires PID operation to be enabled in b5-01.
