R911278870
The R911278870 (DKR02.1-W200B-BE43-02-FW), produced by Bosch Rexroth Indramat, is an effective drive controller with an IP 20 protection category, verifying its compliance with IEC 529 or EN 60529 standards. It’s built to withstand shock resistance up to 8.4g for 5ms, due to its integrated contactor. During operation, heat dissipation is conducted through the in-built heatsink and air vents atop the housing. The unit can handle a maximum pressure of 160Pa and supplies an airflow of 300m3/h. Energy loss of this controller is assessed by considering set switching frequencies and the motor's nominal current rating.
The controller may overheat if the air inlet/outlet is extremely small. Shipped with mounting essentials like flanges, gaskets, and screws, it can be effectively operated in a temperature range of 5°C to 45°C under rated conditions. Sufficient clearance, preferably 160mm, is necessary at the top and bottom for adequate air circulation. Installation faults could cause malfunction, so ensure leads are accurately mounted. Avoid routing control or signal cables near magnetic fields or high-frequency equipment. Connections between the controller and motor are achieved using power and feedback cables, not exceeding 75m for your convenience. Lastly, remember to connect the drive to the control cabinet or mains' grounded connector system.
