Possible reasons for the Fuji Electric FRENIC-ECO not having an output voltage despite normal input voltage include:

1. A surge voltage protection event between power lines and ground.
2. Detection of a momentary power failure lasting more than 15 ms, causing the inverter to stop output.
3. An overload or overheating condition triggering alarm codes (0h1 or 0lu), which reduces or stops output frequency.
4. A broken wire or loss of frequency command, causing the inverter to switch to a preset reference frequency or issue an alarm.
5. Incorrect V/f settings or output voltage too low at low frequency due to variable torque settings.

These conditions can prevent normal inverter output even if input voltage is present.

Consult your Fuji Electric representative if these terminals are to be used. Main circuit power input terminals, L1/R, L2/S, and L3/T (three-phase input) 1) For safety, make sure that the molded case circuit breaker (MCCB) or magnetic contactor (MC) is turned off before wiring the main circuit power input terminals.
Page 43 When connecting a PWM converter with an inverter, do not connect the power supply line directly to terminals R0 and T0. If a PWM is to be connected, insert an insulation transformer or auxiliary B contacts of a magnetic contactor at the power supply side. For connection examples at the PWM converter side, refer to the PWM Converter Instruction Manual.
Page 44: Wiring For Control Circuit Terminals
2.3.7 Wiring for control circuit terminals In general, sheaths and covers of the control signal cables and wires are not specifically designed to withstand a high electric field (i.e., reinforced insulation is not applied). Therefore, if a control signal cable or wire comes into direct contact with a live conductor of the main circuit, the insulation of the sheath or the cover might break down, which would expose the signal wire to a high voltage of the main circuit.

Page 46 Table 2.10 Continued Symbol Name Functions - Since low level analog signals are handled, these signals are especially susceptible to the external noise effects. Route the wiring as short as possible (within 66ft(20 m)) and use shielded wires. In principle, ground the shielded sheath of wires; if effects of external inductive noises are considerable, connection to terminal [11] may be effective.

Page 137 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 variable torque load such as general fans and pumps or for special pump load requiring high start torque.
Page 138 Specifying a high torque boost level will generate a high torque, but may cause overcurrent due to over-excitation at no load. If you continue to drive the motor, it may overheat. To avoid such a situation, adjust torque boost to an appropriate level. When the non-linear V/f pattern and the torque boost are used together, the torque boost takes effect below the frequency on the non-linear V/f pattern’s point.
Page 139 Electronic Thermal Overload Protection for Motor F10 to F12 (Select motor characteristics, Overload detection level, and Thermal time constant) F10 through F12 specify the thermal characteristics of the motor for its electronic thermal overload protection that is used to detect overload conditions of the motor inside the inverter.

Page 142 Restart Mode after Momentary Power Failure (Mode selection) Restart after Momentary Power Failure (Restart time) (Frequency fall rate) (Allowable momentary power failure time) F14 specifies the action to be taken by the inverter such as trip and restart in the event of a momentary power failure.
Page 143 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 144 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 145 Restart mode after momentary power failure (Allowable momentary power failure time) (H16) H16 specifies the maximum allowable duration (0.0 to 30.0 seconds) from an occurrence of a momentary power failure (undervoltage) until the inverter is to be restarted. Specify the coast-to-stop time during which the machine system and facility can be tolerated.
Page 146 Auto-restart after a recovery from 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 voltage is still in a high level, a large inrush current may flow or an overvoltage alarm may occur due to an occurrence of temporary regeneration.
Page 147 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 harmonized 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 149 (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 150 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.
Page 151 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.
Page 152 Output adjustment (F30) F30 allows you to adjust the output voltage or current representing the monitored data selected by function code F31 within the range of 0 to 200%. Function (F31) F31 specifies what is output to the analog output terminal [FMA]. Function Meter scale Data for F31...

Page 163 Inverter running -- (RUN) (Function code data = 0) This output signal is used to tell the external equipment that the inverter is running at a starting frequency or higher. It comes ON when the output frequency exceeds the starting frequency, and it goes OFF when it is less than the stop frequency.
Page 164 Motor overload early warning -- (OL) (Function code data = 7) This output signal is used to issue a motor overload early warning that enables you to take an corrective action before the inverter detects a motor overload alarm and shuts down its output.
Page 165 Cooling fan in operation -- (FAN) (Function code data = 25) Under the cooling fan ON/OFF control enabled (H06 = 1), this output signal is ON when the cooling fan is in operation, and OFF when it is stopped. This signal can be used to make the cooling system of peripheral equipment interlocked for an ON/OFF control.
Page 166 Inverter output on -- (RUN2) (Function code data = 35) This output signal comes ON when the inverter is running at the starting frequency or below or the DC braking is in operation. Overload prevention control -- (OLP) (Function code data = 36) This output signal comes ON when the overload prevention control is activated.
Page 167 Frequency detection (FDT) (Detection level) Frequency detection (FDT) (Hysteresis width) This output signal comes ON when the output frequency exceeds the frequency detection level specified by E31, and it goes OFF when the output frequency drops below the “Frequency detection level (E31) – Hysteresis width (E32).” To utilize this feature, you need to assign FDT (data=2) to any of digital output terminals.

To match the property of a control system with that of the motor, select characteristics of the motor and set H03 (Data Initialization) to "2"...
Page 172 Auto-resetting (Times) Auto-resetting (Reset interval) While the auto-resetting feature is specified, even if the protective function subject to retry is activated and the inverter enters the forced-to-stop state (tripped state), the inverter will automatically attempt to reset the tripped state and restart without issuing an alarm (for any faults).
Page 173 Cooling Fan ON/OFF Control To prolong the life of the cooling fan and to reduce fan noise during running, the cooling fan is stopped when the temperature inside the inverter drops below a certain level while the inverter is stopped. However, since frequent switching of the cooling fan shortens its life, it is kept running for 10 minutes once it is started.
Page 174 Curvilinear acceleration/deceleration Acceleration/deceleration is linear below the base frequency (linear torque) but slows down above the base frequency to maintain a certain level of load factor (constant output). This acceleration/deceleration pattern allows the motor to accelerate or decelerate with the maximum performance of the motor.
Page 175 Searching for idling motor speed to follow The frequency drop caused by the current limiting control during auto search for idling motor speed is determined by the frequency fall rate specified by H14. To use the auto search, be sure to enable the instantaneous overcurrent limiting (H12 = 1). Select starting characteristic (STM) (Digital input signal) The (STM) terminal command specifies whether or not to perform auto search operation for idling motor speed at the start of running.
Page 176 Starting patterns The inverter makes its frequency shift in accordance with the starting patterns shown below to search the speed and rotation direction of the idling motor. When harmonization is complete between the motor speed (including its rotation direction) and the inverter output frequency, the frequency shift by auto search operation is terminated.
Page 177 Instantaneous Overcurrent Limiting H12 specifies whether the inverter invokes the current limit processing or enters the overcurrent trip when its output current exceeds the instantaneous overcurrent limiting level. Under the current limit processing, the inverter immediately turns off its output gate to suppress the further current increase and continues to control the output frequency.
Page 178 = 2 y98 = 2 y98 = 3 For details, refer to the FRENIC-Eco User’s Manual, Chapter 4 "BLOCK DIAGRAMS FOR CONTROL LOGIC" and the RS-485 communication User’s Manual or the Field Bus Option Instruction Manual. • When the (LE) terminal command is assigned to a digital input terminal and the terminal is ON, the settings of function code H30 and y98 are effective.
Page 179 Automatic Deceleration H69 specifies whether automatic deceleration control is to be enabled or disabled. During deceleration of the motor, if regenerative energy exceeds the level that can be handled by the inverter, overvoltage trip may happen. With automatic deceleration enabled, when the DC link bus voltage exceeds the level (internally fixed) for starting automatic deceleration, the output frequency is controlled to prevent the DC link bus voltage from rising further;...
Page 180 Cumulative Run Time of Motor You can view the cumulative run time of the motor on the keypad. This feature is useful for management and maintenance of the mechanical system. With this function code (H94), you can set the cumulative run time of the motor to any value you choose. For example, by specifying "0," you can clear the cumulative run time of the motor.
Page 181 Judgment on the life of DC link bus capacitors Whether the DC link bus capacitor (reservoir capacitor) has reached its life is determined by measuring the length of time for discharging after power off. The discharging time is determined by the capacitance of the DC link bus capacitor and the load inside the inverter. Therefore, if the load inside the inverter fluctuates significantly, the discharging time cannot be accurately measured, and as a result, it may be mistakenly determined that the life has been reached.

Page 184 Dew Condensation Prevention (Duty) When the inverter is stopped, dew condensation on the motor can be prevented, by feeding DC power to the motor at regular intervals to keep the temperature of the motor above a certain level. To utilize this feature, you need to assign a terminal command (DWP) (dew condensation prevention) to one of general-purpose digital input terminals (function code data = 39).
