Hey, I did a lot of research how to switch the motor using an telegram 352 with an s7-1200. I'm using the command 047F to run the motor but my question is when do i need to release or close the brake? I know there is an controle word and there is an status word. I'm not using the brake relay but an relay on the s7-1200 1) Bit 0(STW): Motor is ready for switching on i catch from the invertor 2) when he iss ready then send to the invertor bit 3(enable operation , controle word) 3) Bit 0:ON and Bit 6: enable setpoint i send an cyclus later to the invertor. 4) I get from the invertor bit 1:1 ready for operation and bit 2 operation enabled when does open the brake? when i switch the motor OFF when do i need to close the brake relay(Output S7/1200)? Must i use bit 12 of the status word? I'm new to the G120. See attachement for status and control word. Best regards Thib AttachmentG120_Controle_StatusWord.pdf (253 Downloads) |
