Page 31: Operation Using The Keypad
Chapter 3 OPERATION USING THE KEYPAD This chapter describes inverter operation using the keypad. The inverter features three operation modes (Running, Programming and Alarm modes) which enable you to run and stop the motor, monitor running status, set function code data, display running information required for maintenance, and display alarm data.
Page 32: Overview Of Operation Modes
3.1 Overview of Operation Modes 3.1 Overview of Operation Modes FRENIC-Mini features the following three operation modes: I Running mode : This mode allows you to enter run/stop commands in regular operation. You may also monitor the running status in realtime. I Programming mode : This mode allows you to set function code data and check a variety of information relating to the inverter status and maintenance.

Page 169 - For frequency settings by terminals [12] (voltage) and [C1] (current) and by the built-in potentiometer, setting the gain and bias changes the relationship between those frequency settings and the drive frequency to enable matching your system requirements.

Page 171 Base Frequency Refer to H50. Rated Voltage (at Base Frequency) Refer to H51. These function codes set the base frequency and the voltage at the base frequency essentially required for running the motor properly. If combined with the related function codes H50 and H51, these function codes may set data needed to drive the motor along the non-linear V/f pattern.
Page 172 9.2 Details of Function Codes Defining non-linear V/f patterns (F04, F05, H50 and H51) Function codes F04 and F05 define a non-linear V/f pattern that forms the relationship between the inverter's output frequency and voltage. Furthermore, setting the non-linear V/f pattern using function codes H50 and H51 allows patterns with higher or lower voltage than that of the normal pattern to be defined at an arbitrary point inside or outside the base frequency.

Page 175 150% current of the operation level specified by F11 flows continuously. The time constant of FUJI Electric's general-purpose motors and other induction motors is set to 5 minutes by factory default.
Page 176 9.2 Details of Function Codes Trip immediately (F14 = 0) If an instantaneous power failure occurs when the inverter is in Running mode so that the inverter detects undervoltage of the DC link circuit, then the inverter immediately shuts down its outputs and displays the undervoltage alarm "LU" on the LED monitor. The motor will coast to a stop and the inverter will not restart automatically.
Page 177 • If a coast-to-stop command (BX) is issued during an instantaneous power failure, the inverter exits from the state of waiting for restarting, and enters Running mode. If any run command is issued, the inverter will start at the starting frequency preset. Frequency Limiter (Peak) Frequency Limiter (Bottom) Frequency limiter F15 limits the...
Page 178 9.2 Details of Function Codes Bias (for Frequency Command 1) Refer to C50, C32, C34 and C39. If you select any analog input for frequency command 1, it is possible to define the relationship between the analog input and the set frequency arbitrarily by combining the settings for bias (F18), bias reference point (C50), gains (C32 and C37), and gain reference points (C34 and C39) as shown below.
Page 179 In the above expressions, it is assumed that each function code expresses its data. Example: Setting the bias, gain and its reference point when analog input range from 1 to 5 VDC is selected for the frequency command 1 (Point A) If the analog input is at 1 V, the set frequency is 0 Hz.
Page 180 9.2 Details of Function Codes Starting Frequency Stop Frequency The starting frequency refers to the output frequency that the inverter should output at start up. The inverter shuts down its output at the stop frequency. Set the starting frequency to a level that will enable the motor to generate enough torque for startup.
Page 181 Motor Sound (Tone) Changes the motor running sound tone. This setting is To set the tone Set F27 to: effective when carrier frequencies set to function code level F27 is 7 kHz or lower. Changing the tone level may reduce the high and harsh running noise from the motor.
Page 182 9.2 Details of Function Codes Load Selection/Auto Torque Boost/Auto Energy Saving Operation Allows you to select the load type and enable/disable auto torque boost and auto energy saving operation. The load selection enables an optimal V/f pattern to be selected. Load selection There are two different properties of loads--the torque load which is reversely proportional to the square of speed and the constant torque load.
Page 183 Current Limiter (Operation condition) Current Limiter (Limiting level) F43 enables or disables the current limiter. If it is enabled, the inverter controls the output frequency while keeping the current set to F44 in order to prevent the motor from stalling. With F43, you may select whether the current limiter works during constant speed operation only (F43 = 1) or during both acceleration and constant speed operation (F43 = 2).
Page 184 9.2 Details of Function Codes Calculating discharging capability and allowable loss and then setting function code data Discharging capability (F50) Discharging capability stands for the amount of electric power that a braking resistor can discharge for a single cycle of braking operation. It can be calculated using the braking period and rated motor capacity using equation (1), which is based on the regenerative power in deceleration or equation (2), which is based on that in constant speed operation.

It is intended to apply to the domestic market only.
Page 226: A.2 Noise
Noise This section gives a summary of noises generated in inverters and their effects on devices subject to noise. [ 1 ] Inverter noise Figure A.1 shows an outline of the inverter configuration. The inverter converts AC to DC (rectification) in a converter unit, and converts DC to AC (inversion) with 3-phase variable voltage and variable frequency.
Page 227 App. A Advantageous Use of Inverters (Notes on electrical noise) [ 2 ] Types of noise Noise generated in an inverter is propagated through the main circuit wiring to the power supply and the motor so as to affect a wide range of applications from the power supply transformer to the motor.
Page 228: Noise Prevention
Figure A.5 Electrostatic Noise (3) Radiation noise Noise generated in an inverter may be radiated through the air from wires (that act as antennas) at the input and output sides of the inverter. This noise is called "radiation noise" as shown below. Not only wires but motor frames or control system panels containing inverters may also act as antennas.
Page 229 App. A Advantageous Use of Inverters (Notes on electrical noise) [ 2 ] Implementation of noise prevention measures There are two types of noise prevention measures--one for noise propagation routes and the other for noise receiving sides (that are affected by noise). The basic measures for lessening the effect of noise at the receiving side include: Separating the main circuit wiring from the control circuit wiring, avoiding noise effect.
Page 230 What follows is noise prevention measures for the inverter drive configuration. (1) Wiring and grounding As shown in Figure 1.7, separate the main circuit wiring from control circuit wiring as far as possible regardless of being located inside or outside the system control panel containing an inverter. Use shielded wires and twisted shielded wires that will block out extraneous noises, and minimize the wiring distance.
Page 231 App. A Advantageous Use of Inverters (Notes on electrical noise) (3) Anti-noise devices To reduce the noise propagated through the electrical circuits and the noise radiated from the main circuit wiring to the air, a line filter and power supply transformer should be used (refer to Figure A.10).
