BE05, BE1, BE2 brake The current values IH (holding current) listed in the tables are rms values. Use only ap- propriate instruments for measuring rms values. The inrush current (acceleration cur- rent) IB only flows for a short time (ca. 160 ms) when the brake is released. There is no increased inrush current if a BG or BMS brake rectifier is used or if there is a direct DC voltage supply – only possible with brakes up to size BE2.
