在數控機床上，常用的伺服驅動系統除FANUC公司的產品外，另一主要的產品是SIEMENS的伺服驅動系統。從總體上說，SIEMENS伺服驅動系統亦可以分為直流驅動與交流驅動兩大類，SIEMENS的直流驅動一般都是采用SCR速度控制單元；交流驅動可以分模擬式交流速度控制單元與數字式交流速度控制單元兩種形式。
SIEMENS直流伺服系統一般用于20世紀80年代中期以前進口的數控機床上，配套的CNC有SIEMENS的3、6、8、PRIMOS系統等。常用的規格有6RA26**-6MV30與6RA26**-6DV30兩種規格，前者（6MV30）用于電樞電壓為DC200V的直流伺服電動機驅動，后者（6DV30）用于電樞電壓為DC400V的直流伺服電動機驅動，zui大輸出電流均可以達到175A。驅動器一般與1HU系列永磁式直流伺服電動機（常用）與1GS系列他勵直流伺服電動機配套，組成數控機床的伺服進給驅動系統。驅動系統與CNC的位置控制系統配合，位置增益可以達到301/s以上，適用于大部分數控機床的位置控制。
SIEMENS公司常用的交流模擬式伺服主要有6SC610系列、6SC61lA系列兩種規格。其中，6SC610系列產品為SIEMENS公司早期的模擬型交流伺服驅動產品，它主要與該公司的1FT5系列交流伺服電動機配套，作為數控機床的進給驅動系統使用。系統以±10V模擬量作為速度給定指令，內部采用速度、電流雙閉環控制，PWM調制。該系列產品的伺服驅動獨立組成裝置（不與主軸驅動一體），全部進給軸共用整流電源，軸調節器模塊與功率驅動模塊可根據機床需要選擇。驅動裝置zui大可以安裝6個軸的調節器模塊與功率驅動模塊，輸入電壓為三相交流165V，直流母線電壓為DC210V，6軸zui大總功率可以達到40kW。
6SC611A系列產品為SIEMENS公司在6SC610基礎上改進的模擬型交流伺服驅動產品。它與6SC610的主要區別是：主軸驅動器與伺服驅動器共用電源模塊與控制總線，是一種進給軸、主軸一體化的結構形式，整體體積比6SC610系列大大縮小。6SC61lA系列產品中的伺服驅動器主要與該公司的1FT4、1FT5、1FT6系列交流伺服電動機配套，系統仍然以±10V模擬量作為速度給定指令，其余性能與6SC610相似。
SIEMENS公司常用的交流數字式伺服主要有6SC611D系列、6SC611U系列等規格。其中，SIEMENS 611U/Ue是目前SIEMENS常用的數字式伺服驅動系統，其基本結構與61lA、611D相似，采用模塊化安裝方式，主軸與各伺服驅動單元共用電源。
611U/Ue用于進給驅動的伺服驅動模塊有單軸與雙軸兩種結構型式，帶有PROFIBUSDP總線接口，控制電動機的zui高頻率可以達到1400Hz。伺服驅動模塊帶有SIN/COSlVpp增量編碼器信號接口，編碼器檢測信號可以達到65535脈沖/轉、350kHz，內部還可以進行128倍頻；也可以采用編碼器。611U/Ue驅動器可以與SIEMENS公司的1FT6系列、1FK6系列伺服電動機或IFN系列直線電動機配套，對伺服驅動系統的速度與電流環進行閉環控制。與數控系統配套后，通過CNC的位置環控制，構成全數字式伺服驅動系統。伺服電動機的zui大輸出轉矩可達140N•m。
