Here is the Application Example SINAMICS G120 with SIMATIC S7-1200 programmed in TIA Portal (STEP 7 V12, WinCC and Startdrive): http://support.automation.siemens.com/WW/view/en/70155469 You can download STARTER for free: http://support.automation.siemens.com/WW/view/en/26233208, but of cause you can do it with the BOP to parametrate the drive. You can write controlword and setpoint and read statusword, actual value, output current, torque actual error and actual alarm using the telegram frame 352. So it is not required to use RDREC and WRREC to get this informations. Watch this example, you only have to change the hardware configuration (G120 with CU240B instead of a G120C) http://support.automation.siemens.com/WW/view/en/56749384 |

By reading the manual. If you use telegram frame 1 and the I/O Address is 256, you read in IW 256 (or PIW 256 ) the status word and in IW 258 (or PIW 258 ) the actual value. And you write in IW 256 (or PIW 256 ) the control word and in IW 258 (or PIW 258 ) the setpoint. Control and statusword are describend here. The setpoint and actual values are transferred as standards. The reference values are stored in parameter P2000 of the SINAMICS G120. 16384dec = 4000hex = 100% applies here, with 100% referring to the reference value for the transferred variable. Example: If P2000 (reference speed or reference frequency) is 1500 1/min and if a speed of 500 1/min shall be run, then 33% or 5461dec must be transferred. |

Hello, there are own drive libary for S7-1x00, see: http://support.automation.siemens.com/WW/view/de/68034568 With "FB285" it is very comfortable - you send only a ON command instead of thinking about all control word bit`s and so on. The speed is defined as "rpm" instead of "HEX-" (percent) values. Zako |
