1. The preceding conguration takes the synchronous motor as an example. The asynchronous
motor has poor energy transfer efciency, and you can reduce the power of the regen. resistor or
increase the resistance of the regen. resistor.
2. It is recommended that you select the regen. resistor closest to the minimum resistance.
3. "x 2" indicates that two sets are required. Take NICE-L-C-4110 as an example: "9 x 2, 18000 x 2,
MDBUN-90-T x 2" indicates that two sets of (9 Ω, 15000 W) regen. resistor + MDBUN-90-T braking
unit are connected in parallel to the controller. "x 3" indicates that three sets are required.
