3.2 Advanced Tuning Parameters (Vector Control Only)
The following parameters can only be viewed when the parameter acces level is set to
“2 = Advanced” in Param Access Lvl (196).
Current Limit Integral gain. This gain is applied to the current limit error signal to
eliminate steady state current limit error. A larger value increases overshoot during a
step of motor current/load.
Current Limit Derivative gain. This gain is applied to the sensed motor current to
anticipate a current limit condition. A larger value reduces overshoot of the current
relative to the current limit value.
This proportional gain, in conjunction with Bus Reg Ki (160), adjusts the output
frequency of the drive during a bus limit or inertia ride through condition. The output
frequency is adjusted in response to an error in the active, or torque producing,
current to maintain the active bus limit, or inertia ride through bus reference. A larger
value of gain reduces the dynamic error of the active current.

ATTENTION: To guard against unstable or unpredictable operation, the
following parameters must only be changed by qualified service
personnel. Failure to observe this precaution could result in damage to
equipment or severe bodily injury.
