Remark： The external brake resistance must be configured when drawing
machine inverter matches wire retracting motor. The reason is that inverter need to
be provided bigger start-up and brake current and it brings out higher DC bus
voltage when it accelerates and decelerates in short period. Technique index and
spe.of EDS1100 Series inverter indicated as attached list 1-2.
