2.0 Safety in Installation and Operation

2.1 Installation Precautions

1) Install in a secure and upright position in a well ventilated location that is out

of direct sunlight. The ambient temperature should be between -10° C and 40° C (up to 50° C when not enclosed in a cabinet).

2) Allow a clearance space of 4 inches (10 cm) for the top and bottom and

2 inches (5 cm) on both sides. This space will insure adequate ventilation. Use care not to obstruct any of the ventilation openings.

3) Avoid installation in areas where vibration, heat, humidity, dust, steel particles,

or sources of electrical noise are present.

4) Adequate working space should be provided for adjustment, inspection and

maintenance.

5) Adequate lighting should be available for troubleshooting and maintenance.

6) A noncombustible insulating floor or mat should be provided in the area

immediately surrounding the electrical system where maintenance is required.

7) Always ground the unit to prevent electrical shock and to help

reduce electrical noise. A separate ground cable should be run inside the conduit with the input, output, and control power

cables (See Grounding Section 4.3). The metal of the conduit is not an

acceptable ground.

CAUTION

8) Connect three phase power of the correct voltage to input terminals L1, L2, L3

(R, S, T) and connect three phase power from output terminals T1, T2, T3 (U, V, W) to a motor of the correct voltage and type for the application. Size the conductors in accordance with Selection of Main Circuit Wiring Equipment and Standard Cable Sizes Section 4.2.

9) If conductors of a smaller than recommended size are used in parallel to share

current then the conductors should be kept together in sets i.e. U1, V1, W1 in one conduit and U2, V2, W2 in another. National and local electrical codes

should be checked for possible cable derating factors if more than three power

conductors are run in the same conduit.

10) Install a molded case circuit breaker (MCCB) between the power source and the

inverter. Size the MCCB to clear the available fault current of the power source.

11) Use separate metal conduits for routing the input power, output power, and control circuits.

12) Installation of inverter systems should conform to the National Electrical Code,

regulations of the Occupational Safety and Health Administration, all national, regional or industry codes and standards.

13) Do not connect control circuit terminal block return connections marked CC to

inverter earth ground terminals marked GND(E). See Simple Connection Diagrams Section 4.1 and Terminal Connections and Functions Section 4.10.

TOSHIBA

2.1 Installation Precautions (cont'd)

14) If a secondary Magnetic Contactor (MC) is used between the inverter output

and the load, it should be interlocked so the ST-CC terminals are disconnected before the output contactor is opened. If the output contactor is used for bypass operation, it must also be interlocked so that commercial power is never applied to the inverter output terminals (U,V,W).

2.2 Operating Precautions

1) Do not power up the inverter until this entire operation manual is reviewed.

2) The input voltage must be within +/-10% of the specified input voltage. Voltages

outside of this permissible tolerance range may cause internal protection devices to turn on or can cause damage to the unit. Also, the input frequency should be within +/-2 Hz of the specified input frequency.

3) Do not use this inverter with a motor whose rated input is greater than the rated

inverter output.

4) This inverter is designed to operate NEMA B motors. Consult the factory before

using the inverter for special applications such as an explosion proof motor or one with a repetitive type piston load.

CAUTION

5) Do not touch any internal part with

remove the source power and check that the charge and power LED's are out.

A hazard exists temporarily for electrical shock even if the source power is removed.

6) Do not operate this unit with the cabinet door open.

7) Do not apply commercial power to the output terminals T1 (U), T2 (V), or T3 (W)

even if the inverter source power is off. Disconnect the inverter from the motor before applying a test or bypass voltage to the motor.

8) Use caution when setting output frequency. Overspeeding of the motor can cause serious damage to the motor and/or the driven load equipment.

9) Use caution when setting the acceleration and deceleration time. Unnecessarily

short times can cause undue stress and tripping of the drive.

10) The G2+ series of inverters can be operated in a special PWM high carrier

frequency mode for low acoustical noise. When operating in this special mode, where the carrier frequency is greater than 3 KHz, special programming procedures and operating precautions must be followed. Failure to follow

these special programming procedures and operating precautions may result in damage to the inverter and can invalidate the factory warranty

(Contact Toshiba for additional operating and programming information).

DANGER

power applied to the inverter. First

11) Interface problems can occur when this inverter is used in conjunction with

some types of process controllers. Signal isolation may be required to

prevent controller and/or inverter damage (Contact Toshiba or the process controller manufacturer for additional information about compatibility and signal isolation).

2 - 2

TOSHIBA

2.2 Operating Precautions (cont'd)

12) Do not open and then re-close a secondary magnetic contactor (MC) between

the inverter and the load until the inverter has been turned OFF (output frequency has dropped to zero) and the motor has stopped rotating. Abrupt re-application

of the load while inverter is ON or motor is rotating can cause inverter

damage.

13) Personnel who have access to the adjustments and operation of this equipment

should be familiar with these drive operating instructions and with the machinery being driven.

14) The operator of the drive equipment should be properly trained in the operation

of the equipment.

15) Follow all warnings and precautions; do not exceed equipment ratings.

2.3 Confirmation of Wiring

Make the following final checks before applying power to the unit:

1) Confirm that source power is connected to terminals L1, L2, L3 (R, S, T).

Connection of incoming source power to any other terminals will damage the inverter.

2) The 3-phase source power should be within the correct voltage and frequency

tolerances.

3) The motor leads must be connected to terminals T1, T2, T3 (U, V, W).

4) Make sure there are no short circuits or inadvertent grounds and tighten any

loose connector terminal screws.

CAUTION

2.4 Start-Up and Test

Prior to releasing an electrical drive system for regular operation after installation, the system should be given a start-up test by competent personnel. This assures

correct operation of the equipment for reasons of reliable and safe performance. It is important to make arrangements for such a check and that time is allowed for it.

When power is applied for the first time the inverter will come up in the factory settings (See section 6.7 and 6.8). If these settings are incorrect for the application trial run then, before activating the run button, the correct settings should be programmed from the control panel. The inverter can be operated with no motor connected. Operation with no motor connected or use with a small trial motor is recommended for initial adjustment or for learning to adjust and operate the inverter.

2.5 Maintenance

1) Periodically check the operating inverter for cleanliness.

2) Keep the heatsink free of dust and debris.

3) Periodically check electrical connections for tightness (make sure

power is off and locked out).

4.2 Selection of Main Circuit Wiring Equipment and Standard Cable Sizes (Cont'd)

* The customer supplied Molded Case Circuit Breaker (MCCB) or Magnetic Circuit

Protector (MCP) should be coordinated with the available short circuit current. The units are rated for output short circuit faults of 5000A (1 - 50 HP), 10,000A (51 - 200 HP), and 18,000A (201 - 400 HP) according to the UL 508 "Standard for Industrial Control Equipment" Table 57B.4 or CSA Standard C22.2 No.14-M1987 "Industrial Control Equipment" Table 24. The selection of breakers for this table is in accordance with 1987 NEC Article 430. The selection of these breakers takes into consideration motor starting at the low end of the output voltage specifications but does not consider the use of high efficiency motors.

* For multiple motor applications, the magnetic only MCP should be replaced by a thermal

magnetic MCCB. The MCCB should be sized according to 1.25 X (largest motor Full Load Amps) + (sum of all other motor Full Load Amps) to meet National Electric Code (NEC) or Canadian Electrical Code (CEC) requirements.

** Wire sizing is based upon NEC table 310-16 or CEC Table 2 using 75 deg C cable, an

ambient of 30 deg C, cable runs for less than 300 FT., and copper wiring for not more than three conductors in raceway or cable or earth (directly buried). The customer

should consult the NEC or CEC wire Tables for his own particular application and wire

sizing.

** For cable runs greater than 300 FT., consult the factory before installing. *** Use two parallel conductors instead of a single conductor (this will allow for the proper

wire bending radius within the cabinet). Use separate conduits for routing parallel conductors. This prevents the need for conductor derating (see note 3 this page).

Notes:

1.) Auxiliary relays used to switch inverter signals should be capable of switching

low current signals (i.e. 5mA).

2.) The inverter has internal overload protection, but the Local, National, or

Canadian Electrical Codes may require external motor overload protection.

3.) When wiring with parallel conductors, the conductors should be kept together in

phase sets with U1, V1, W1 in one conduit and parallel conductors U2, V2, W2 in another conduit. The ground conductor should be in one of these conduits.

Use separate conduits for routing incoming power, power to

CAUTION

motor, and control conductors. Use no more than three power conductors and a ground conductor per conduit.

4.3 Grounding

The inverter should be grounded in accordance with Article 250 of the National Electrical Code or Section 10 of the Canadian Electrical Code, Part I and the grounding conductor should be sized in accordance with NEC Table 250-95 or CEC, Part I Table 16.

CAUTION

Conduit is not a suitable ground for the inverter.

TOSHIBA

Commands are easily entered via the inverter's keyboard type operating panel. The operating panel enables the user to run/stop the inverter, read/change the operating function settings, and monitor the operating conditions of the inverter. All these operations are accomplished via the inverter's user-friendly software, keypad, and 7 segment LED display. See section 6 for details on the operating panel.

With the G2+, the user can directly access and change any of the built-in functions. The software was designed to make programming and set-up time extremely fast and easy. There is no need to scroll through a long list of functions or flip numerous dip switches just to set one particular function.

Accessing and setting the individual functions can be performed with or without a motor being attached. In fact, all but two of the inverter's functions can be accessed and changed while an attached motor is running.

Monitoring the inverter's operating conditions requires the pressing of a single key. Items which can be monitored include the inverter's output current and output voltage. See section 7.5 for a complete list of items.

The NEMA 4/12 operating panel can be placed up to 5M (15ft) from the inverter's chassis, without any additional electronics, simply by using an optional cable. This feature allows for the continued ease of operation should the inverter be placed inside an enclosure.

In cases where an unknown number of functions may become misadjusted when settings and start over rather than search for the misadjusted functions. Refer to "First

and Second Functions Factory Setting Overview" section 6.6 for these settings.

The example on the following page shows how easy it is to access and set a function. The standard setting mode of function 0 establishes the nominal operating frequency of the motor that is selected. This function is also used to set all functions back to their original factory settings. The example shows this is done by setting "typ" to 3.

5.2 "96" Built-in Functions for Complete Operating Control

The G2+ inverters have a wide variety of operating functions with each function having a wide adjustment range. To the user, this means that almost any application can be controlled to produce maximum output at minimum cost. For ease of programming,

functions are classified into first and second functions. See the Factory Overview

5.3 Voltage Matching

5.3.1 Proportional Output Voltage (Standard)

This feature allows programming the inverter to deliver an output voltage that is an exact percentage of the input voltage. The output voltage can range from 0% to 100% of the input voltage. The word "proportional" comes from the fact that if the input voltage level rises or falls during operation, the output voltage follows in direct proportion. The following examples illustrate this feature.

5.3.2 Output Voltage Regulation (Optional)

This optional feature enables the user to maintain a constant output voltage even if voltage fluctuations occur at the input. For minimal fluctuations, the V/F characteristics can be maintained at a constant level by automatically regulating the output voltage. Instantaneous fluctuations should be minimized by the use of an input AC line reactor. The use of this feature insures that the proper V/F characteristics will be applied in critical applications. Also this minimizes the danger of motor over excitation due to an elevated input voltage.

5.7 Accelerating/Decelerating Characteristics

· ACC/DEC time can be set in the range of 0.1~6000 seconds.

· ACC/DEC time 1 or 2 can be selected either through the keypad (Panel Control) or an input terminal (Remote Control).

· ACC/DEC characteristics can be selected from the linear, S-shaped, or C-shaped pattern.

Linear pattern S-shaped pattern C-shaped pattern

Max output frequency

Frequency

The S-shaped pattern gradually accelerates a motor in a range where the motor provides a low torque, and is suited for material handling machinery. The C-shaped pattern quickly accelerates a motor in a range where the motor provides a low torque, and is suited for a high speed run.

5.8 Display Frequency Scaler

This versatile unit indication system permits the indication of not only the output frequencies, but also revolution speeds, linear velocities, or other linear multiples of the frequencies.

[Contents of digital displays]=Constant X [Output frequency] The constant can be set within the range 0.01~200; also the unit measure (Hz) LED turns off when the Display Frequency Scaler function is activated. Example: When a 4 pole motor is driven at 0~60Hz, the setting "dSP.2=30" makes the monitor display indicate 0~1800 (rpm). For linear speed of 6m/sec at 60Hz, set "dSP.2=0.1". When speed scaling is used, the unit of measure LED is turned off.

5.9 Memory Function

A number from 0 to 31 can be assigned to and stored in the non-volatile memory of the inverter. This allows electronic tagging and on-line identification of each unit. This function can be utilized for sorting of inverter unit numbers and various set data through the optional computer interface.

5.10 Braking Characteristics

5.10.1 DC Injection

The DC injection braking function creates smooth operating characteristics with continuous phase control. It is used primarily for alignment applications. It controls the final coast of the motor by injecting DC voltage into the motor. This allows the capability of starting and stopping at the same point every time when used in conjunction with a position sensor. The amount of DC energy that is available for injection is limited by the current limiting feature of the inverter. Care should be taken when using DC injection because of additional motor heating.

Note:

See standard specifications (page 3-2) for adjustment ranges.

5.10.2 Dynamic Braking

Dynamic braking is used to rapidly decelerate the motor load (especially high inertia loads) by converting the energy generated by the motor into heat. The heat is dissipated through the DB resistor. Models G2+2010 through G2+430K can be equipped with an optional dynamic braking resistor (DBR) to boost the braking torque. When DBR's are installed:

1) Install a magnetic contactor (MC) or a molded case circuit breaker (MCCB) with a trip coil on the inverter's power supply side. This opens the power circuit when the inverter's built-in fault detecting relay (FL) or an externally mounted overload relay is activated.

2) For all models, connect the dynamic braking resistor (DBR) bank to the PA-PB terminals of the main circuit terminal block.

3) The DB resistors should not be installed where the ambient temperature of the inverter will exceed 40°C.

5 - 9

TOSHIBA

5.10.2 Dynamic Braking (cont'd)

4) DB resistors should be installed as near to the inverter as possible with temperature constraints in mind.

Note:

5) Exercise caution when working around extremely hot when used in conjunction with long duty cycles and high

inertia loads.

6) PA-PB dynamic braking high DC bus voltage potential. Do not touch PA - PB terminals when

the charge or power LED lamp is on.

Consult factory for DBR sizing.

7.0 Basic Operations

This inverter's almost limitless capabilities are made possible by the use of highly sophisticated software. The software allows keys to be used for more than one function. Identification of the inverter's basic keys, simple operation examples, method for accessing available functions, and the monitoring codes are presented in Section 7.

Note:

The inverter can be operated from either the keypad (PANEL CONTROL) or through remote signal inputs (REMOTE CONTROL).

7.1 Basic Keys

TOSHIBA

RUN STOPCTRL See Section 6.4.

2ND NEXT CLR WRTMON READ

Every function/feature available with the inverter can be accessed, changed, monitored, and/or activated by using these keys in conjunction with the numerical keys (0 thru 9).

As shown in Section 6.5, each numerical key has three (3) separate functions assigned to it: numerical value, 1st Function, and 2nd Function. The operating function of this key depends on the key sequence preceding the numerical key data entry.

See Section 6.5.

7.2 Simple Operation

The following example illustrates how easy it is to set, change, and run the inverter at different frequencies.

Pressing this key decreases the value displayed. Once 55Hz is reached the WRT key can be pressed. The display will flash "55" and "FC" indicating the setting has been made.

Note: Pressing the key increases the value displayed. Engages the run command. The inverter output frequency will "ramp up"

to 55Hz, causing the motor to accelerate to its 55Hz speed. Pressing the STOP key engages the stop command. The inverter's output frequency will "ramp down" to 0Hz, causing the motor to decelerate to a stop.

The inverter's operating frequency can be changed during any normal run, without

stopping the motor.

8.0 Operating Procedures

A thorough understanding of the G2+ inverter's operating procedures and functions is necessary to gain maximum use of the many versatile features. This includes understanding the uses for all of the available functions, how the software is structured, and the programming techniques used. An understanding of the use of the input and output terminals is also necessary.

Section 8 identifies operating procedures and teaches keyboard data flow and terminal functions so the user can program the inverter to fit almost any application.

Section 8 is broken into separate sub-sections that explain the functions of both the keypad data entry and the terminal input logic. Each function is explained and some step-by-step procedures are shown with keystroke, action, and display examples.

8.1.2 Coast to Stop

This inverter is capable of instantly removing power from a rotating motor and allowing it to coast to a stop. This can be accomplished without removing power from the inverter. The procedure will override the inverter's normal deceleration pattern. Activation of the coast to stop function is illustrated below:

The emergency stop function can only be used when operating by remote control. When activated, the inverter can perform the same coast to a stop function as described in section 8.1.2. In an emergency, valuable time can be saved by being able to remove power to the motor from the local inverter instead of from the distant remote control station. Activation of the emergency stop is illustrated below:

Activating the Emergency Stop

Assume the inverter is operating at 60HZ due to some type of remote input signal (REMOTE CONTROL).

"EOFF" flashes but the unit continues running. Pressing

STOP once more will activate the stop, however pressing CLR CLR will cancel the procedure.

Activates the emergency stop function. A fault detection signal is ouput via terminals FLA, FLB, FLC.

CLR

WRT

Resets the inverter and its fault detection contacts. The inverter is now ready for normal operation.

Note:

Resetting the inverter from a remote location is accomplished by momentarily short-circuiting terminals RST to CC. These terminals are located on the inverter's terminal strip.

8.1.4 Emergency Stop From a Remote Location

A SPST normally closed latch-in type of switch should be connected between ST-CC. This switch can then be located in a remote location. When the switch is "toggled" to latch open, the motor will coast to a stop.

CAUTION

Do not toggle this switch ON again until the inverter is

turned OFF (the output frequency reads zero) and the motor

load has stopped rotating.

1) With ST-CC (ON), switching F-CC or R-CC (OFF) will cause the motor to decelerate to a stop.

2) If input power is turned off (with MCCB) while inverter is running, the motor will coast to a stop.

3) Acceleration and Deceleration rates are determined by the preset values of 1st Function #2 (ACC/DEC).

4) When switching from a forward run to a reverse run the motor will decelerate to a stop, then accelerate in the reverse direction.

Unlike the Preset Speed Function, the user can pre-select the length of time in which the inverter will operate at each frequency (Sr1-Sr7), as well as the acc/dec pattern used to reach each frequency.

The required preset function parameters are as follows:

1) Actual run frequencies (Sr1~Sr7) are located in 1st Function #6 (Section

8.3.4).

2) The run time for each of these frequencies in the pattern (Pt.1t~Pt.7t) is located in 2nd Function #8.

3) The particular ACC/DEC drive characteristics to be used, as well as the run direction (Pt.1~Pt.7) located in 2nd Function #8.

8.3.5 Pattern Run (Cont'd)

The run time set for each pattern includes the ACC/DEC time required to reach that particular run frequency. Therefore, care must be taken when choosing run times. For example, if the pattern run time is set for 30 seconds and the acceleration time required to reach the preset frequency is 20 seconds, then the actual run frequency would last only 10 seconds.

8.5.3 Fault-Detection Output Terminals

When any of the inverter's system protection features are activated and the inverter trips (see list of probable causes in section 7.5.2), the cause of the problem will be displayed and the fault-detection relay will be activated. This will cause the contacts associated with the Fault-Detection Output Terminals to change state.

8.5.4 Resetting After a Trip

The inverter can be reset after a trip by two methods:

1) Pressing the CLR and WRT keys on the operating panel resets the inverter locally.

2) Momentarily closing a normally open contact between terminals RST and COM resets the inverter remotely.

When the inverter trips due to an emergency stop or the activation of one or more of its protective functions, the

cause of the fault must be corrected before resetting the inverter. A forced restart with out prior fault correction measures could damage the inverter and connected devices.

8.7 Operating Functions - Descriptions and Examples

Some features not previously introduced, but just as important, are found in this section along with all of the other features and functions.

FIRST FUNCTIONS

Selects standard setting mode and sets maximum safe frequency (FH) for motor being run.

FMAX

TOSHIBA

V/F

ACC/DEC

UL/LL

VOLTAGE BOOST - Increases the start-up torque of the motor being run. AUTO TORQUE BOOST - Automatically increases the percentage of voltage boost

when starting torque requirements are abnormally high. FREQUENCY at MAXIMUM VOLTAGE - Sets the frequency at which the output voltage

is 100%.

V/f PATTERN - Selects a constant or variable torque pattern. ACC1, DEC1, Pt1/ACC2, DEC2, Pt2 - Sets the times required to ACC/DEC between

0Hz and the maximum frequency value FH. Also selects the pattern by which the ACC/DEC times are run (see section 5.7) SEL2 - Selects which ACC/DEC/Pt will be used (#1 or #2). Note: ACC/DEC times are the times required to go between 0Hz and the maximum

frequency FH.

UPPER LIMIT - Sets the upper frequency limit. The inverter will never operate above this upper limit. Note: The value of FH must always be equal to or greater than the value of UL.

LOWER LIMIT - Sets the lower frequency limit. The inverter will never operate below this lower limit.

Application Example - The inverter is used to control a 50Hz motor which has a safe operating frequency of 80Hz. This motor drives a conveyor belt which must run according to the following specifications: "tyP=1" "FH=80" ACC/DEC times are the times required to go between 0Hz and FH.

1) For this example, a VOLTAGE BOOST OF 10% is needed to move the conveyor at low start-up speeds: "ub=10"

2) Although a 50Hz motor is used, specifications require 100% output voltage at 60Hz: "uL=60"

3) Conveyor belt systems require a constant torque: "Pt=0"

4) When running the conveyor the inverter must run no faster than 60Hz and no slower than 20Hz: "LL=20" "UL=60"

5) The maximum acceleration and deceleration between 20Hz and 60Hz must be 30 seconds and 10 seconds respectively. A linear pattern is required.

100

Because ACC/DEC times are based upon the change in Hz/SEC the following formula must be used.

FH/Frequency range X (ACC/DEC time of frequency range) = ACC/DEC

ACC1 = 80Hz : (60-20Hz) X 30 sec. = 60 sec. ACC1=60 DEC1 = 80Hz : (60-20Hz) X 10 sec. = 20 sec. DEC1=20

Note:

Specifications required only one ACC/DEC rate, therefore ACC2/DEC2/Pt2 settings were not needed: SEL2=0 Setting ACC2/DEC2/Pt2 would be suggested if a different pattern was required. Switching between the two patterns would then simply require switching between SEL2=0 and SEL2=1.

OVERLOAD PROTECTION - Sets the thermal overload detection level to match the ratings and characteristics of the motor being used (10% to 100% of rated output current). The inverter will run continuously at 110% of the overload protection (i.e. Setting: inverter rated current = 50amps, overload level set at 60% leads to set rated current = 50 X 60% = 30amps and continuous set rated current = 30 X 110% = 33amps).

STALL PROTECTION - Sets the activation level of the stall protection function (90% to 150% of rated output current). When the stall level is reached the inverter will begin stalling by lowering the frequency and voltage to prevent overcurrent tripping. Once a soft stall has occurred the output current will be clocked. If output current is not reduced within a specified time a fault will occur. (See section 3.0 for ratings and section 7.5.2 for fault codes.)

Note:

Instantaneous trip current limits are factory set and are dependent upon inverter size as well as the motor ripple current. The inverter's soft stall function is particularly effective in situations where load current decreases as revolution speed decreases (i.e. wind and hydraulic power machinery).

Application Example - A 3HP 230V G2+ inverter is used to drive a 2HP 230V motor rated at 6.8 amps full load. Because the inverter is rated at 10 amps there is a danger of burning up the motor. By using the overload features of the inverter the output current can be limited and the stall protection level adjusted accordingly.

displayed alternately on the monitor display. Fault-detection signals are not output during the inverter's reset process. If the cause of the failure has not been corrected, then the intervals before each attempted reset will be prolonged. See above chart.

If the load exhibits an extremely large amount of inertia (WK)2, automatic restart using the procedure described above may not work.

Note:

No restart is tried when any of the following messages is displayed on the inverter's monitor display:

"OCA" Overcurrent (transistor short-circuited at start-up) "OCL" Overcurrent (load end short-circuit at start-up) "OCr" Overcurrent (overcurrent through the regenerative discharge resistor) "EF" Ground fault "E" Emergency stop "EEP" E2PROM failure

CAUTION

AUTO-RESTART - When selected, the inverter will automatically restart into a freerotating motor. This restart will occur only after an instantaneous power interruption has occurred. The function allows the inverter to sample the speed of the free-rotating motor during the interruptions and output a matching frequency when power is reapplied. This assures smooth restarts of a free-running motor when an instantaneous power loss has occurred such as when the system is switched from a commercial bypass run to an inverter run.

Note:

With ArSt=0, the inverter will restart at 0Hz and increase up to the initial running frequency. With ArSt=1, the inverter will restart at the running frequency of the motor and will increase up to the initial frequency of the inverter.

Before using the inverter's retry (auto-reset) function, check to be certain that the auto-reset procedure will not damage or otherwise cause problems for the load machine system when the inverter's retry operations are being executed.

REGENERATION POWER RIDE THROUGH CONTROL - Uses regenerative energy to extend the inverter's power ride through capability during momentary power dropouts.

START-UP FREQUENCY - Sets the frequency at which the inverter will begin operating. In the panel control setting mode the frequency display will change as the "up" and "down" keys are pressed. However, an actual output does not occur until the startup frequency is reached. In the terminal input mode the display will remain at zero until the start-up frequency is reached. This function, along with the voltage boost function, enables the user to obtain an optimum voltage boost level. See figures below.

RUN FREQUENCY - Selects a frequency to initiate inverter run/stop control. RUN FREQUENCY HYSTERESIS - Used to offset inverter run frequency. When the frequency reference signal reaches the Frun + Fhys point, the drive will ramp

the motor to that speed. The inverter will continue to follow the reference signal until it falls below the Frun - Fhys at which time the drive will ramp the motor to a stop. See figure below.
