JB/T 11728-2013Electrical control systems of numerically controlled high-speed wood cut-off machines - Specification (English PDF)

1 Foreword

JB/T 11728-2013 was issued by MIIT on 31 December 2013 and has been in force since 1 July 2014.

2 Scope

This standard is a recommended standard of the Chinese machinery industry dealing with the electrical control system of numerically controlled high-speed wood cut-off machines. It fixes the basic requirements that govern the design, the manufacture and the inspection of such a control system. It applies to machines whose nominal supply does not exceed AC 1000 V or DC 1500 V and that also meet a rated frequency condition. The document is filed under the Chinese classification J50 and the international classification 25.082. Among the standards it quotes are GB/T 4026-2010, GB 5226.1-2008, GB/T 8870.1-2012, GB/T 15969.1-2007, GB/T 24340-2009 and GB/T 26675-2011.
