You should use Telegram 1, this are two words: The PLC sendsthe control word and the setpoint to the drive and the drive the statusword and the actuale value. The control and statusword you can find here: http://support.automation.siemens.com/WW/view/en/71762451Chapter 7.3.1.1 ----------------------------------------- To change the ramp times you have to write to parameters. P1120 and P1121. Accessing parameters from a PLC is possible but a more complex. ----------------------------------------- As I wrote in my first post there a several ways to change the direction. ----------------------------------------- Setpoint and actual value are transfered in the 2nd word of the PROFINET telegram and uses a normalisation: 100%=4000hex=16384dec= the value of P2000 in the G120 ----------------------------------------- Example: Control word: The drive starts when the control word changes from 047E to 047F. Frequency setpoint and actual value: The frequency setpoint and actual value are normalised such that 4000hex corresponds to 1500 1/min (assuming P2000 of G120is 1500). The maximum value that should be sent is 7FFF (This is 2999,91 1/min). Here are some typical control and status words to get started (in HEX):
If you use a SIMATIC you can use this examples: S7-300 in STEP7 V5: http://support.automation.siemens.com/WW/view/en/58820849 S7-300 in TIA Portal: http://support.automation.siemens.com/WW/view/en/60140921 S7-1200 in TIA Portal: http://support.automation.siemens.com/WW/view/en/70155469 This examples incude the access to the ramp time paramerters too. --------------------------------------------- *) This will do the same as the orginal line above, but uses a negative setpoint instead of setting the control word bit 11 to rotate in the other direction:

If "block motor" means to make shure it does not run, you should use the integrated safety function STO. refer to this manual (and/or the exampels listed in the post bevore)how to do it. |
