Given its role as a Servo PLC, ensure that control wiring for digital I\/O and the System Bus is kept separate from high-voltage motor cables to prevent electromagnetic interference from disrupting the internal logic. All feedback and communication cables must be shielded, with the shield grounded at the drive's EMC plate using 360-degree clamps. Before operation, verify that the 24 VDC control voltage is stable and that the grounding of the control cabinet backplane is consistent, as the high-speed electronics in the 9300-Series are sensitive to voltage transients and ground loops.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Lenze","offers":[{"title":"Default Title","offer_id":53105065951595,"sku":"EVS9321-EI","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/evs9321-ei-hppliv3ia3b.png?v=1776236518","url":"https:\/\/www.plcprotech.com\/products\/evs9321-ei-lenze-9300-series-0-37-kw-intelligent-servo-plc","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
