Take conveyer belt for example. Its necessary torque does not change with the motor speed. And constant torque usually needs larger starting torque. As the motor generates heat easily when constant torque is applied to lower speed, it is better to increase the horsepower or use the motor special for AC motor drive with constant cooling fan. VT: It is applied to variable-torque load. Such as pump, fan…etc. They are centrifugal machines, who use AC motor drive usually for energy saving. For example, when a fan is running at 50% of the full speed, its necessary torque is smaller than when it is running at full speed. As for the drive with variable torque, it can provide the motor only with necessary torque to save energies. In the applications like this, the maximum transient loads needn’t to be provided extra power. So the drive with variable torque is applied widely for its load endurance. What’s more, the overload current endurance of the drive with constant torque is 150% of rated current for 1 minute, while the drive with variable torque only 120% of rated current for 1 minute because the current of centrifugal machines rarely exceed the rated current. In addition, its starting torque is smaller than that of constant torque.

15. V/f FOC Control Parameters Position Control Torque Control Speed Control Torque Torque Control at Low Speed Torque Control at Zero Speed Frequency ： the function of running speed Voltage: constant V/Hz to maintain constant flux. Frequency, voltage and vector ( phase relations among magnetic field, rotor and stator) use precise current loop adjustor to control current. No control. Speed error is relevant to the motor slip curve. The torque is proportional to the slip. To calculates the optimum slip so that can generate maximum torque and apply it into the whole speed range. Open-loop control. The running speed is not linear in the speed range. It provides linear speed control from 0 to basic speed. Slip induces rotor current to generate torque. Because current and toque can not be instantly controlled, so dynamic response is not good. Magnetic rotor’s flux vector value would be precisely controlled, so that torque can be controlled instantly. Can not be done cause couldn’t control motor torque and it is open-loop control which mean no encoder feedback. Vary precisely because the current of generating torque and the excitation current can be precisely and separately controlled. Also It is available to use encoder feedback for position control. Worse; because frequency reduced will cause rotor’s impedance increase which makes stator and rotor’s coupling become smaller. Armature current does not generate proportional torque which makes motor running efficiency worse. Better: Rotor’s flux vector can be controlled so that it makes rotor’s flux and current vector maintain at 90°. Stator and rotor has the minimum coupling effect which normally only 30% of the rated torque It can be up to 150% of rated torque. AC Motor Drive Comparison between V/Hz and FOC

31. Beside traditional PI control, VE-series also provides PDFF function to reduce overshoot. To enable PDFF function, it need to: 1.Must know inertia first 2.Set 11-00 to 1 3.Adjust 11-04 (the larger number is set and the suppressed overshoot function will be better. But it will cause worse system response) Vector control-PDFF It is recommended to disable this function (Pr. 11-04=0) for Y- △ connection switch and ASR1/ASR2 switch application PDFF PI

43. DEB Function (Deceleration Energies Regeneration) The DEB (Deceleration Energy Backup) function is the AC motor drive decelerates to stop after momentary power loss. When the momentary power loss occurs, this function can be used for the motor to decelerate to 0 speed with deceleration stop method. When the power is on again, motor will run again after DEB return time. ( Can be applied to high speed spindle motor) It doesn't need multi- function terminals DC BUS LV level Soft-start relay ON level (LV+30V) DEB return time counting level (LV+30V+58V) 07-14 Soft-start Relay DEB function is activated Output frequency DEB return time Pr. 07-13 DEB DEC. Time Status 1: Insufficient power supply due to momentary power-loss/ unstable power (due to low voltage)/ sudden heavy-load When Pr. 07-14 is set to 0, the AC motor drive will be stopped. Drive will not ACE. To the frequency before DEB even the power has return

44. Status 3:Some brand can enable DEB function via external terminal. For VFD-VE series, the DEB function can be used by combine deceleration time and EF function. For example, in textile machinery, you will hope that all the machines can be decelerated to stop to prevent broken stitching when power loss. In this case, the system controller will send a signal to the drive, thus, it can be done via combine DEB and EF function. DEB Function (Sequel) DC BUS voltage LV level Soft-start relay ON level (LV+30V) DEB return counting time level (LV+30V+58V) 07-14 Soft start relay DEB function is activated Output frequency DEB return time DEB DEC. time 07-13 Status 2: unexpected power off, such as momentary power loss

45. This function is used to enhance the unstable speed/position due to analog resolution no enough. It needs to use with external input terminals (Pr 02-11~Pr.02-14 set 43). Set Pr. 10-25 as analog input resolution switch frequency Max. frequency for resolution switch of analog simulation value Resolution switch 02-11~02-14 =d43 FORWARDREVERSE AUI 0V AUI +10V AUI -10V Max. output frequency Pr.01-00 Resolution switch frequency Pr. 10-25 Output frequency 0Hz Max, frequency switch waiting time
