Note that function codes closely related each other for the implementation of an inverter's operation are detailed in the description of the function code having the youngest identifying number.
  • Page 140 Certain source settings (e.g., communications link and multistep frequency) have priority over the one specified by F01. • You can modify the reference frequency anywhere you choose using the gain and bias settings, to these analog inputs (voltages entered via terminals [12] and [V2]; the current entered via terminal [C1]).
  • Page 141 In addition to the run command (F02) described, there are several other sources available with priority over F02: Remote/Local switching, Communications link, Run forward command 2 (FWD2), and Run reverse command 2 (REV2). The table below shows relationship between keying and run commands in running per standard keypad (F02 = 0, rotation direction is defined by the digital inputs).
  • Page 142 Maximum Frequency F03 specifies the maximum frequency at which the motor can run. Specifying the frequency out of the range rated for the equipment driven by the inverter may cause damage or a dangerous situation.

For details, contact your Fuji Electric representative. V/f characteristics The FRENIC-Eco series of inverters offers a variety of V/f patterns and torque boosts, which include V/f patterns suitable for non-linear torque load such as general fans and pumps or for special pump load requiring high start torque.
  • Page 149 Torque boost • Manual torque boost (F09) In torque boost using F09, constant voltage is added to the basic V/f pattern, regardless of the load, to give the output voltage. To secure a sufficient start torque, manually adjust the output voltage to optimally match the motor and its load by using F09.
  • Page 150 Auto energy saving operation This feature automatically controls the supply voltage to the motor to minimize the total power consumption of motor and inverter. (Note that this feature may not be effective depending upon the motor or load characteristics. Check the advantage of energy saving before actually apply this feature to your power system.).
  • Page 151 The figure below shows operating characteristics of the electronic thermal overload protection when F10 = 1. The characteristic factors α1 through α3 as well as their corresponding switching frequencies f2 and f3 vary with the characteristics of the motor. The tables below lists the factors of the motor selected by P99 (Motor Selection).
  • Page 152 Overload detection level (F11) F11 specifies the level at which the electronic thermal overload protection becomes activated. - Data setting range: 1 to 135% of the rated current (allowable continuous drive current) of the inverter In general, set F11 to the rated current of motor when driven at the base frequency (i.e. 1.0 to 1.1 multiple of the rated current of motor (P03)).

Restart mode after momentary power failure (Mode selection) (F14) Data for F14 Mode...
  • Page 154 Restart mode after momentary power failure (Basic operation) The inverter recognizes a momentary power failure upon detecting the condition that DC link bus voltage goes below the undervoltage level, while the inverter in running. If the load of the motor is light and the duration of the momentary power failure is extremely short, the voltage drop may not be great enough for a momentary power failure to be recognized, and the motor may continue to run uninterrupted.
  • Page 155 When the power is recovered, the inverter will wait 2 seconds for input of a run command. However, if the allowable momentary power failure time (H16) elapses after the power failure was recognized, even within the 2 seconds, the waiting time for a run command is canceled.
  • Page 156 Restart mode after momentary power failure (Allowable momentary power failure time) (H16) Specifies the maximum allowable duration (0.0 to 30.0 seconds) from a momentary power failure (undervoltage) occurrence until the inverter is to be restarted. Specify the maximum length of time that can be tolerated in terms of the machine system and facility during which the motor can coast to stop.
  • Page 157 Auto-restart after momentary power failure (Waiting time) (H13) This function specifies the time period from momentary power failure occurrence until the inverter reacts for restarting process. If the inverter starts the motor while motor’s residual electricity is still in a high level, an overvoltage alarm may be recognized due to a high inrush current or temporary regeneration occurrence.
  • Page 158 Restart after momentary power failure (Frequency fall rate) (H14) During restart after a momentary power failure, if the inverter output frequency and the motor rotation cannot be synchronized with each other, an overcurrent will flow, activating the overcurrent limiter. If it happens, the inverter reduces the output frequency to match the motor rotation according to the reduction rate (Frequency fall rate: Hz/s) specified by H14.
  • Page 159 Even if you select the continuous running control, the inverter may not be able to continue operation when the load's inertia is small or the load is heavy, due to undervoltage caused by a control delay. Even in such a case, however, the output frequency when the undervoltage alarm occurred is saved and the inverter will restart at the saved frequency after a recovery from the momentary power failure.
  • Page 160 Frequency Limiter (High) Frequency Limiter (Low) Refer to H63. F15 and F16 specify the upper and lower limits of the output frequency, respectively. H63 specifies the operation to be carried out when the output frequency drops below the frequency limiter (Low) specified by F16 as follows: •...
  • Page 161 Bias (Frequency command 1) Refer to C50, C32, C34, C37, C39, C42 and C44. When any analog input for frequency command 1 (F01) is used, it is possible to define the relationship between the analog input and the reference frequency by multiplying the gain and adding the bias specified by F18.
  • Page 162 Example: Setting the bias, gain and its reference points when the reference frequency 0 to 100% follows the analog input of 1 to 5 VDC to terminal [12] (in frequency command 1). (Point A) To set the reference frequency to 0 Hz for an analog input being at 1 V, set the bias to 0% (F18 = 0). Since 1 V is the bias reference point and it is equal to 10% of 10 V, set the bias reference point to 10% (C50 = 10).

  • Page 164 Starting Frequency Stop Frequency At the startup of an inverter, the initial output frequency is equal to the starting frequency. The inverter stops its output at the stop frequency. Set the starting frequency to a level that will enable the motor to generate enough torque for startup. Generally, set the motor's rated slip frequency at the starting frequency F23.
  • Page 165 Specifying a too low carrier frequency will cause the output current waveform to have a large amount of ripples (many harmonics components). As a result, the motor loss increases, causing the motor temperature to rise. Furthermore, the large amount of ripples tends to cause a current limiting alarm.
