MOVIDRIVE® MOVITRAC® 31C MOVIDYN® MOVIMOT® Addendum to the Installation and Operating Instructions UWS11A Interface Adapter Edition 06/98 • This addendum does not replace the detailed Installation and Operating Instructions! • Equipment may only be installed by qualified electrical personnel in compliance with the applicable accident prevention regulations and the Installation and Operating Instructions! UWS11A Interface Adapter (Part number 822 689 X) The UWS11A option converts RS-232 signals (e.g. from a PC) to RS-485 signals which are then routed to the RS-485 interface of the respective unit. The UWS11A requires a 24 VDC power supply in accordance with EN61131-2, VIN = 24 VDC -15% / +20% (range 19.2...30 VDC). The maximum power consumption of the option is Imax = 100 mA. The connection between the UWS11A and the PC is made with a shielded commercial interface cable (max. length 5 m (16.5 ft)). The RS-485 interface allows up to 32 units to be networked for communications purposes (max. cable length = 200 m (660 ft)). The UWS11A option has inbuilt dynamic terminating resistors, external terminating resistors must not be connected! 1 2 3 4 5 RS-485 1 2 3 4 5 24V ⊥ RS+ RS⊥ + = 24 VDC - MOVIDRIVE X13: 9 DGND 10 ST11 11 ST12 ® ® max. 5 m (16.5 ft) RS-232 RS-232 MOVITRAC 31C X8: 67 RS-485+ 68 RS48530 0V24 UWS ® MOVIDYN X41: (MKS) X02: (MPB, MPR) 1 RS-485+ 2 RS-4853 0V5 0919 5815 / 0698 MOVIMOT X2: RS+ RS⊥ The UWS11A is mounted on a DIN rail (EN50022-35 × 7.5) in the switch cabinet. ® 01744AXX Dimensions UWS11A in mm (in): W × H × D = 22.5 (0.89) × 75 (2.96) × 83 (3.27) SEW-EURODRIVE GmbH & Co ♦ P.O.
