图1-3-9 欧姆龙三种制动电阻外形及安装尺寸
(a) 3G3IV-PCDBR□B制动单元; (b) 3G3IV-PERF15WJ□安装型制动电阻; (c)3G3IV-PLKEB□安装型制动电阻单元
制动电阻就是能耗制动电阻RB。制动电阻的选择包括电阻的阻值和电阻的容量 (功率),前者决定制动时流过的电流大小,后者决定电阻容许的发热量。由于制动电阻通常工作在断续工作制,因此,电阻容量的选择应考虑工作时间。
欧姆龙 (omRon) 生产的3G31V-PCDBR□B制动单元、3G31V-RERF安装型制动电阻、3G31V-RLKEB□安装形制动电阻单元。其外形及安装尺寸见图1-3-9。
选择时参见表1-3-7。
