Hi to all Now i control micromaster 440 through profibus.the MM440 used for high pressure pump. I SET IN BOP RAMP UP TIME 20SEC RAMP DOWN TIME 40SEC I am using 2wire control method. i attached the diagram below. The High pressure output in Q4.7. The high pressure output connected to MM440 5th & 9th terminal. When the high pressure pump on MM440 get supply.i switch on the drive ready commend(profibus control) while high pressure pump on.i attached the diagram below. I give constant power supply to main supply of MM440. MY QUESTION IS IF I SWITH OFF THE HIGH PRESSURE PUMP Q4.7. THE MM440 DON'T GET SUPPLY IN THAT TERMINAL. (5&9) DOES NOT CLOSE 1.WHEATHER THE HIGH PRESSURE PUMP IMMEDIATLY OFF OR AFTER 40 SEC(RAMP DOWN TIME) 2. IF IMMEDIATELY OFF MEAN WHAT I SHOULD DO FOR RAMP DOWN.

Dear sunder, I think to my knowledge if you are using ON/OFF1 for digital input 1(terminal 5, P701=1). After you give signal ON it’ll start with ramp up and when you disconnect input it’ll stop with ramp down. But I think you are using profibus so you can take that input to PLC and you can start/stop MM440 through profibus. For that it will be useful this link. I hope this will help you. Regards. |

thanks The drive control terminal get input from PLC output. using profibus i control the speed of the motor.i didn't go to commisioning yet.this is my first project in drives. i set the parameters what i attached below. if there is any modification pls help me to rectify. i set the parameters using my attachment information. your setting should also allow the speed control (using profibus). pls send me the modified value in change column in my attachment.
