✩Optional dynamic braking resistor capacities are selected for an operation rate of 3%ED.
✩To connect a dynamic braking resistor, set the overvoltage limit operation parameter to "1" (Disabled).
✩To use this inverter in applications that create a continuously regenerative status (such as down- ward movement of a lift, a press or a tension control machine), or in applications that require slowdown stopping of a machine with a significant load inertial moment, increase the dynamic braking resistor capacity according to the operation rate required.
✩To connect an external dynamic braking resistor, select one with a resultant resistance value greater than the minimum allowable resistance value. Be sure to set the appropriate operation
rate in to ensure overload protection.
✩To use a braking resistor without a thermal fuse or to use a braking resistor in mode
" " of , connect thermal relays as shown in the diagram above, to make an operation cir- cuit for stopping operation.
