Hello, Generally, to achieve higher speeds, the drive inverter output frequency is appropriately increased; this has the disadvantage that the motor torque is reduced. http://support.automation.siemens.com/WW/view/en/25338130 refering to parameterl list: http://support.automation.siemens.com/WW/view/en/10804923/133300 P1080 = Min. frequency P1082 = Max. Frequenz P2000 = Reference frequency |

Hi, there are only this efficiency-data availabel: Power factor _ 0.95 Inverter efficiency 0.12 kW to 75 kW: 96 % to 97 %; 90 kW to 200 kW: 97 % to 98 % To run your motor follow tis steps: P0010 Start Quick Commissioning P0010 must always be set back to ‘0’ before operating the motor. However if P3900 = 1 is set after commissioning this is done automatically P0100 Operation for Europe / N. America For setting 0 and 1 use DIP Switch 2. For setting 2 use P0100 P0304 Rated Motor Voltage Nominal motor voltage (V) from rating plate P0305 Rated Motor Current Nominal motor current (A) from rating plate P0307 Rated Motor Power Nominal motor power (kW) from rating plate. If P0100 = 1, values will be in hp Rated Motor Frequency Nominal motor frequency (Hz) from rating plate P0310 Rated Motor Frequency Nominal motor frequency (Hz) from rating plate P0311 Rated Motor Speed Nominal motor speed (rpm) from rating plate P0700 Selection of Command Source 1 = BOP 2 = Terminal / Digital Inputs (default) P1000 Selection of Frequency Setpoint 1 = BOP 2 = Analogue Setpoint (default) P1080 Min. Motor Frequency Sets minimum motor frequency (0 - 650 Hz) at which the motor will run irrespective of the frequency setpoint. The value set here is valid for both clockwise and anticlockwise rotation.Be aware that below 10Hz your mote can be over heated. P1082 Max. Motor Frequency Sets maximum motor frequency (0 - 650 Hz) at which the motor will run at irrespective of the frequency setpoint. The value set here is valid for both clockwise and anti-clockwise rotation P1120 Ramp-Up Time Time taken for the motor to accelerate from standstill up to maximum motor frequency. P1121 Ramp-Down Time Time taken for motor to decelerate from maximum motor frequency down to standstill P3900 End Quick Commissioning 0 = End Quick Commissioning without motor calculation or factory reset. 1 = End Quick Commissioning with motor calculation and factory reset (Recommended). 2 = End Quick Commissioning with motor calculation and with I/O reset. 3= End Quick Commissioning with motor calculation but without I/O reset. for further information pls see Getting Started Guide: http://support.automation.siemens.com/WW/view/en/38644522 |
