6-24 Mounting and Installation Rexroth IndraDrive Multiple-Line Arrangement of Drive Controllers Control Cabinet with Multiple-Line Structure Note: Particular attention should be paid to the maximum allowed air intake temperature of components when they are arranged in multiple lines in the control cabinet. Where necessary, cooling air guides are to be provided with blowers specially used for this purpose. additional blower conveying direction of heated air in flow-off area intake area of cooling air for upper device line conveying direction of heated air in flow-off area intake area of cooling air for lower device line outlet air to cooling unit air guide supply air from cooling unit Fig. 6-30: Example of arrangement for multiple-line structure with components DOK-INDRV*-FU*********-IB01-EN-P
Rexroth IndraDrive Mounting and Installation 6-25 6.2 Electrical Installation DOK-INDRV*-FU*********-IB01-EN-P Note: For successful project planning of the electrical installation with regard to EMC, also observe the Project Planning Manual on the drive system Rexroth IndraDrive. The explanations below will help you detect and remove malfunction. Rules for Design of Installations with Drive Controllers in Compliance with EMC Mains Filter Control Cabinet Grounding Line Routing Interference Suppression Elements Twisted Wires Lines of Measuring Systems Digital Signal Lines Analog Signal Lines The following rules are the basics for designing and installing drives in compliance with EMC. Correctly use a mains filter recommended by Rexroth for radio interference suppression in the supply feeder of the AC drive system. All metal parts of the cabinet have to be connected with one another over the largest possible surface area to establish a good electrical connection. This, too, applies to the mounting of the EMC filter. If required, use serrated washers which cut through the paint surface. The cabinet door should be connected to the cabinet using the shortest possible grounding straps. Avoid coupling routes between lines with high potential of noise and noise-free lines, therefore signal, mains and motor lines and power cables have to be routed separately from another (this eliminates mutual interference!). Minimum clearance: 10 cm. Provide separating sheets between power and signal lines. Separating sheets have to be grounded at several points. Lines with high potential of noise at the drive controller are lines for the mains supply (incl. mains synchronization), lines at the motor connection and DC bus connections. Generally, interference injection are reduced by routing cables close to grounded sheet steel panels. For this reason, cables and wires should not be routed freely in the cabinet, but close to the cabinet housing or mounting panels. The incoming and outgoing cables of the radio interference suppression filter have to be separated. Contactors, relays, solenoid valves, electromechanical operating hour counters etc. in the control cabinet must be provided with interference suppression combinations. These combinations must be connected directly at each coil. Non-shielded cables belonging to the same circuit (feeder and return cable) have to be twisted or the surface between feeder and return cable has to be kept as small as possible. Ground cables that are not used at both ends. Lines of measuring systems have to be shielded. The shield has to be connected to ground at both ends and over the largest possible surface area. The shield may not be interrupted, e.g. using intermediate terminals. The shields of digital signal lines have to be grounded at both ends (transmitter and receiver) over the largest possible surface area and with low impedance. Bad ground connection between transmitter and receiver requires additional routing of a bonding conductor (min. 10 mm²). Braided shields are to be preferred to foil shields. The shields of analog signal lines generally have to be grounded at one end (transmitter or receiver) over the largest possible surface area and
