    Overload Characteristic 2.6 Time dependent overload curve If the load current exceeds the rated current but is below the over current level, an overload timer begins counting. The rate at which the timer increments is a function of load current. The higher the current the faster the increments. When the counter reaches the limit the fault E.OL is triggered and the output to the motor is shut off.

The COMBIVERT F5 will drop the carrier frequency to 4kHz if necessary to be able to continue to provide current to the motor. Once the output frequency rises above 3Hz or the current drops below the levels listed below, the carrier frequency will be returned to the higher value.

  • Page 56: Initial Start-Up

    Initial Start Up 5. Initial Start-up 5.1 Selecting The Confi guration Before trying to operate the drive it is necessary to establish the correct mode of operation. The F5 drive is capable of driving different types of motors both open and closed loop. Therefore prior to operation, the type of motor and mode of operation (open or closed loop) must be established.

  • Page 57: Setting The Control Type

    Initial Start Up 5.3 Setting The Control Type The COMBIVERT drive supports six different control modes, digital speed selection and control, analog speed control, analog torque control. The drive’s I/O will need to be set up according to the desired scheme. From the table below select the desired control scheme and adjust the corresponding number in parameter LF.2.

  • Page 58: Induction Motor Data

    Initial Start Up 5.5.2 Induction Motor Enter the motor rated speed (rpm) in LF.11. For IM this value is not Data the synchronous speed but the full load rpm which is always less than synchronous speed. An example is a 6 pole motor; the synchronous speed is 1200 rpm but the rated speed is lower, about 1165 rpm.
  • Page 59 Initial Start Up 3) If the controller is providing the speed command via analog or serial command, set the inspection speed value in the controller to zero. If the drive is providing the command there is no need to change the inspection speed in the drive.

    Initial Start Up 5.6 PM Synchronous Motors 5.6.1 Motor Overload The COMBIVERT drive is capable of providing solid state motor overload protection. If it is desired that the drive provide this protection, turn the function “on” in parameter LF.08. The drive uses the motor current from LF.12.

  • Page 61: Auto-Tuning Pm Motors

    Initial Start Up 5.6.3 Auto-Tuning PM For best performance the resistance and the inductance of the PM motor motors must be measured by the drive. Use the following steps to complete the measurement for PM synchronous motors. Set up 1) Make sure the rated motor speed (LF.11), rated motor current (LF.12), rated motor frequency (LF.13), rated motor torque (LF.17) and contract speed (LF.20) are entered into the drive before you begin.

  • Page 62: Machine Data

    Initial Start Up FAIL : the measurement sequence was interrupted, i.e. the inspection switch was released prematurely, or the controller dropped the enable signal to the drive. Verify if the controller is dropping the signal by fi rst setting LF.3 to conf and try again. If the controller still drops the enable and the motor contactor, the problem lies in the controller.

    Initial Start Up 5.8 Encoder Parameters LF.26...LF.29 and optionally parameters LF.76 and LF.77 are Feedback used to establish the encoder feedback. 5.8.1 Encoder card The most important point is to verify that the installed feedback card matches verifi cation the encoder type on the motor. The drive supports many different types of encoders, some of which require different feedback cards as options.

    Initial Start Up 5.8.3 Other encoder Enter in LF.27 the pulses per revolution of the encoder, i.e. 1024, 2048, adjustments 4096 etc. LF.28 can be used to swap the encoder channels such that the encoder is incrementally counting in the same direction as the motor. Initially leave this parameter set to 0 or no reversal.

  • Page 66 Initial Start Up Initial Steps 1) Verify the motor is correctly connected to the drive, i.e. phase U->U, V->V, W->W. With PM motors you can not have an arbitrary phasing. If direction reversal is required, the system direction can be reversed in LF.28 after the pole position is learned.

  • Page 67: Absolute Encoder Setup (No Ropes)

    Initial Start Up FAILd: The encoder position samples are not consistent within 4,000 counts after 11 samples. In this case try the procedure again and note the learned values. If all displayed values are consistent, it would be sufficient to use an approximate average and enter it into LF.77.
  • Page 68 Initial Start Up the actual position value of the encoder. As the motor moves this value will change. When the motor rotor has aligned with a pole, the value will stabilize. At this point, the alignment has been found. Continue holding the inspection switch as the drive will then try to move the motor clockwise and counter clockwise to verify the motor’s rotation is consistent with the encoder’s.

  • Page 69: Absolute Encoder Setup (With Ropes)

    Initial Start Up The following will outline the procedure for aligning an absolute encoder for 5.11.3 Absolute Encoder use with a permanent magnet motor and the following encoders: HIPERFACE, Setup (with ropes) ENDAT, SIN/COS. The motor must be mounted in place and be electrically connected to the elevator controller.
  • Page 70 Initial Start Up Alignment Process 1) Set LF.3 = P Lrn. The display should confi rm with StArt. 2) Press and hold the inspection up switch. Motor current will begin to fl ow in one phase and the current will ramp up to the motor’s rated value. The motor sheave should turn slowly and then stop when the motor rotor has lined up with one of the motor poles.

  • Page 71: Absolute Encoder Position Verifi Cation

    Initial Start Up 4) For high speed runs under load, it may be necessary to raise 0.LF.36 to a higher value. This value should not be set to a value higher than the motor manufacturer’s peak torque value, usually 2.0 to 2.4 times the motor’s rated torque.

    Initial Start Up 5.11.5 Encoder It is necessary to determine whether or not the motor encoder is in Synchronization phase with the rotation of the motor. As an example the motor is turning clockwise and the encoder is indicating clockwise rotation. The problem TTL, H T L , SI N /C OS comes when the encoder indicates rotation opposite to the actual rotation...

  • Page 73: High Speed Tuning

    Initial Start Up 5.12 High Speed Tuning For optimum control of the elevator, it is recommended to learn the system 5.12.1 System Inertia inertia and activate the feed forward torque controller. Feed forward control Learn reduces the dependence on the speed feedback from the motor by predicting what the system will do and providing the required torque command based on that prediction.

  • Page 74: Feed Forward Torque Control, Fftc

    Initial Start Up 9) Run the car up and down a few times. Note that during the acceleration, the same value should be reached and then a much lower value during the constant speed portion of travel. Disregard the values during deceleration.

  • Page 75: Speed Gain Adjustment

    Initial Start Up 5.12.3 Speed When not using the FFTC or when the gain of the FFTC must be kept lower, Gain Adjustment the speed control gains play a greater rol in controlling the elevator. Always start adjustment with the proportional gain LF.31 and then proceed on the the integral gains in LF.32 and LF.33.
  • Page 76 Initial Start Up LF.31 = 5000 Loud audible noise or vibration from the motor, lower the value in steps of 500 until the noise/vibration stops. LF.42 Integral Gain The integral gain is responsible for correcting long term average error in speed as well as providing increased control and rigidity at lower speeds for starting and stopping.
  • Page 77 Initial Start Up LF.33 provides an offset to the gain value at low speeds. Again this parameter provides two adjustments; one for acceleration and one for deceleration. During starting and stopping it is necessary to have higher gain values to overcome friction as well as maintain good control.
