  • Page 56: Changing Parameters

    Basic control operations Programming of the frequency inverter enables the drive to be adapted to your application. The possible settings are arranged in codes, which are numbered in ascending order and start with the letter "C". Each code provides one parameter which can be selected according to the application.

  • Page 58: Parameter Setting By Two Codes

    2.1.1 Parameter setting by two codes Some parameters are set by two codes. A preselection code is used to select the parameter which is to be changed. The parameter is then changed by another code. For example, to set the JOG frequency JOG3, first set the preselection code C038 to -3- and then set the desired frequency for JOG3 via code C039.

  • Page 59: Operating Mode

  • Page 66: Features Of Set-Value

    Features of set-value 1 An analog entry of set-value 1 is possible via input X1/terminal 8, otherwise it is entered via the keypad or the LECOM interfaces. This depends on the selected operating mode (C001). The configuration determines whether the input is unipolar, bipolar, or independently of the operating mode, a digital frequency input.

  • Page 67: Digital Frequency Input

    3.4.2 Digital frequency input With the corresponding configuration (C005) you can use the 9-pole Sub-D socket X5 or X8 as digital frequency input, where two complementary signals shifted by 90° are provided. If you use an HTL-encoder, it is sufficient to provide only the signals A and B. The inputs A\ and B\ must then be bridged using +Vcc (pin 4).

  • Page 68: Features Of Set-Value

    Features of set-value 2 Set-value 2 can only be provided via the differential input X1/terminals 1,2, independently of the selected operating mode (C001). Its value can only be displayed in per cent under code C049. Set-value 2 is processed first by a special ramp generator, before it is added to set-value 1.The ramp times of the ramp generator are set separately via C220 and C221.

  • Page 69: Control Mode

    Gain Set the signal gain after the offset adjustment. First apply that signal to which you want to adjust the internal display (see offset). Then select under C025 the corresponding analog input. Adjust the signal gain such that the desired set-value is obtained.

  • Page 70: V/F Characteristic Control

    3.7.1 V/f characteristic control You have to change from I control (factory setting) to V/f characteristic control if you want to supply several drives with different loads or rated power from one inverter. Also for pump and blower drives to be operated with a square characteristic, a V/f characteristic control is required.
  • Page 71 Voltage boost V In the low speed range, the obtained torque is determined largely by the set voltage boost. If you set V (C016), make sure that the motor cannot be destroyed by overheat. Experience tells that self-ventilated standard asynchronous machines of insulation class B can be operated in a frequency range up to 25Hz only for a short time with rated current.

  • Page 72: I0 Control

    3.7.2 I control "I control" is especially suited for machines with a large breakaway torque. Compared to the V/f characteristic control it provides considerably larger torques up to the motor rated point. The advantages of I control can be used especially for single drives.

  • Page 73: Minimum Field Frequency Fdmin

  • Page 74: Acceleration And Deceleration Times Tir, Tif

    3.10 Acceleration and deceleration times T The ramp generators (main set-value, set-value 2) are programmed using the acceleration and deceleration times. Under C012 and C013, the ramp generator for the main set-value (Set- value 1/JOG frequency) receives its standard setting. The acceleration and deceleration times refer to a change of the field frequency from 0 to the maximum field frequency set under C011.

  • Page 75: Analog Feedback

    Closed-loop speed control For a number of applications, the accuracy which can be obtained with open-loop speed control is often not sufficient. To avoid a speed reduction which occurs when an asynchronous motor is loaded, you can select a configuration with a PI controller. The appropriate configuration depends on the way of set-value input and the actual value input you want to use.

  • Page 76: Frequency Pilot Control

    Frequency pilot control For applications where the feedback signal is directly proportional to the speed of the drive (actual speed) it is advantageous to pilot- control the output frequency with the set-value or feedback. The influence of the PI controller can be limited such that only the maximum machine slip to be expected is controlled.

  • Page 77: Adjustment Of The Feedback Gain

    Closed-loop control without pilot control, closed-loop control of an application datum The PI controller is normally used for the speed control of the connected motor. The large setting ranges of the control parameters also allow the control of an application datum if this depends on the drive speed.

  • Page 78: Manual Adjustment

    4.4.2 Manual adjustment If, for technical reasons, the above described automatic adjustment in idle running is not possible or too inaccurate, you can measure the motor speed by hand and calculate the required feedback gain. Proceed as follows: • Activate the closed-loop speed control (C005) with pilot control of the output frequency by the controller reference (C238 = -1-).

  • Page 80: Freely Assignable Digital Inputs

    Programming of the freely assignable inputs and outputs Most of the inputs and outputs of the frequency inverter are freely assignable via their own codes, i.e. they can be especially assigned to the required signals. Furthermore, these signals can be adjusted in the best possible way by setting facilities. In factory setting, these inputs are already assigned to certain functions.

    Except for the functions "Enable JOG frequencies", "Enable additional acceleration and decleration times" and "Select parameter set", every function can only be assigned to one terminal. If you want to re-assign an input, the previous programming is lost. A function can only be assigned to one input. A double assignment is not possible.
