Hello,
I will be controlling two Siemens MicroMaster 440 VFD's through profibus.
Does anyone have any sample ladder logic or can point me to a Siemens manual that shows how to start and stop the Siemens MicroMaster 440 VFD?
I know that the drive has a control word but I don't know how the control word is handle in the pLC (S7300). I am writing the program in ladder.(per cust req)
I have started and stopped drives using Allen Bradley PLC's with DeviceNet, but Siemens with Profibus is new to me.
Is Siemens with profibus like Allen Bradley's Devicenet?
I have the Micromaster 440 drive book and I know how the Control word for the drive is set up, (bit00 = on/off) (bit01 = Electrical stop) (Bit03=Pulse enable) but I don't know how the PLC program addresses the drives control word. (Address and function)
Thanks in advance...
