04-05=5: DC braking current
Multi-function analog input AI2 can be used to adjust the DC Injection braking current.
DC braking current parameter 07-07 setting should be set to 0% to use this function.
The inverter rated current = 100%

04-05=6: Over-torque detection level
Multi-function analog input AI2 can be used to adjust the over-torque detection level.
100% of inverter rated current (V/f or V/f + PG control mode)
100% motor rated torque (SLV or SV control mode)
If the multi-function analog input is used to adjust the over-torque level, the internal over-torque detection level
(08-15) is disabled.

4-05=7: Stall prevention level during running
Multi-function analog input AI2 can be used to adjust the stall prevention level during operation.
Inverter rated current = 100%. When AI2 is set to control stall prevention level (04-05 = 7) and parameter 08-
03 (Stall prevention level during operation) is used, then the lesser of the two value becomes the active stall
prevention level during operation.
Example: If the motor power is less than that of the inverter, the operation and the stall prevention of the motor
will be based on the factory settings, multi-function analog input AI2 can be used to reduce the stall prevention
level during operation.
