Motor leads of 200 feet become a problem for motors under about 100hp at 460V. The lower the hp, the shorter the leads can be before needing at least a 3% load reactor. For example, if you have a 5hp motor, the problem is so severe that a load reactor is not enough. You would need at least a dv/dt filter and maybe more. At 50hp, the reactor would be enough.
As to input filters, first check to see if your brand and model of drive already has one. If not, then you must do a harmonic analysis to determine what your power network harmonic content will be. If above the specs of IEEE519, you will want to start adding filters.
