上次不小心误将升压器当隔离变压器,结果炸机,修好以后,进行通讯,系统屏幕显示如下(以前用wincc通讯没有类似故障发生):
Data transmission problem of the CP5613/CP5614 !
-> Cause:
a) short circuit on the bus line
b) problems with the bus terminator
c) defect station
d) wrong bus parameters (double station address, TTR is too low, wrong baudrate, ..)
e) other disruptions.
Data transmission problem !
DW_Para1: 0x0 DW_Para2: 0x0
只好将profibus通讯改为uss通讯,在simovis中显示连接良好,但系统无法识别从站,修改地址,系统也可以识别,对应的模块显示为绿色ok。请问这是怎么回事,CB15应该没有问题,故障是不是出在变频器内部?请赐教!!
