当变频器和PLC的电压信号范围不同时,如变频器的输入信号为0~10V,而PLC的输出电压信号范围为0~5V时;或PLC的一侧的输出信号电压范围为0~10V而变频器的输入电压信号范围为0~5V时,由于变频器和晶体管的允许电压、电流等因素的限制,需要用并、串联的方式接入电阻,以次来限制电流或分去部分电压,以保证进行开闭时不超过PLC和变频器相应的容量。此外,在连线时还应注意将控制电路和主电路分开,控制电路**采用屏蔽线,保证主电路一侧的噪音不传到控制电路Siemens 6AM4900-1AA00-1AA0 + 2x 6AM4940-2AA00-1AA0 Siemens 6AM4900-1AA00-1AA0 + 6AM4940-2AA00-1AA0 + 6AM4940-1AB00-1AA0Heidenhain 358655-10 MELSEC MITSUBISHI A616DAIRexroth MDD115B-N-020-N2L-130GA0 R911247437 Siemens 6FX1127-3AB00 Johnson Pumpe SPX CL65-160 Siemens 7ME6320-4PB12-2AA2 Lenze MCS 19**0-RS0B0-B28N-ST5S00N-R0SU Siemens 6FC5357-0BB15-0AA0Siemens C79040-A445-C9-03-86 + 6AM4935-0AC00-1AA0 + 6AM4900-0AB00-1AA0Grundfos-Zirkulati**pumpe LP 65-125/117 A-F-A-BUBESiemens 1PH7133-2QG02-0C
