Hi, it sounds that you need to do a commissioning (set up parameter exactly) with your MM440. As first what Control mode you are using? I suggest using SLVC – with that you do not need boost. See p1300 Possible Settings: 0 V/f with linear characteristic 1 V/f with FCC 2 V/f with parabolic characteristic 3 V/f with programmable characteristic 4 Reserved 5 V/f for textile applications 6 V/f with FCC for textile applications 19 V/f control with independent voltage setpoint 20 Sensorless vector control 21 Vector control with sensor 22 Sensorless vector torque-control 23 Vector torque-control with sensor If you are using linear characteristic or FCC the boost is: P1310[3] Continuous boost P1311[3] Acceleration boost P1312[3] Starting boost Did you do a motor identification routine? - see FAQ below Getting Started Guide: MICROMASTER 420/430/440 http://support.automation.siemens.com/WW/view/en/38645759 Parameter List: MICROMASTER 440 http://support.automation.siemens.com/WW/view/en/23708204 Operating Instructions: MICROMASTER 440 0,12 kW - 250 kW http://support.automation.siemens.com/WW/view/en/24294529 FAQ How can I use Sensorless Vector Control (SLVC) on the MM440 or SINAMICS G120? http://support.automation.siemens.com/WW/view/en/7494205 How can I optimize the standard motor identification routine (MOT-ID) for VC and SLVC? http://support.automation.siemens.com/WW/view/en/37690358 |
