DEVELOPMENT OBJECTIVES
TOYOTA 1.6 ~ 3.0 ton FBMF 16 ~ 30 counterbalance type electric 4-wheel forklift trucks have had an estab­lished reputation as high performance forklift trucks since first their model launched in 1989. There have been rising demands for clean electric forklift trucks with relevant to environmental concern; and fur­ther the market wants higher capacity forklift than 3.0 ton beside the existing capacity models. Keeping these points in mind, the design concepts were established, as follows:
1. AC induction motor Making best use of the advantages of AC induction motor drive system to respond to customer's needs for the most suitable load handling system.
2. SAS - System of Active Stability In order to gain better stability, SAS has been developed. SAS, adopted by 7 series, has already won high con­fidence from the industrial truck markets. This same level of stability will be incorporated into the new 7FBMF 16 ~ 50 models.
3. Introducing larger capacity models of 3.5 ton and over in addition to new 1 ~ 3 ton capacity models to en­hance the product range.
Creation of over 3.5 ton capacity models has been undertaken together with the model changes launched for 1 ~ 3 ton capacity models. Most of all, the AC induction drive motor system has been a pioneering endeavor having rallied our technological powers for a successful introduction in our products. Excellent features inherent to AC induction motor have been used to its full advantages with success. Furthermore, varied demands for additional features have been implemented. Emphasis has been placed on system design development such as the mini-lever system and the wet brake system, etc. The 7FBMF 16 ~ 50 models certainly have outstanding features compared to other forklift models. On operation, the differences are so obvious in fundamentals, performance, comfort, etc. New 7FBMF 16 ~ 50 models are commendable as an epoch in new era.

AC POWER SYSTEM
AC system in industrial trend
Industries have already employed AC power system by making use of its features. Three major features are:
System design advantages
Simpler and smaller
1
construction of motor
Three-phase AC control
2
realizes wider control range.
Motor brushes and contactors are dispensed with.

Thereby industrial truck engineers worldwide have already been aware of the splendid features of AC power sys­tem to be implemented in electric forklift trucks. New AC drive motor systems have been adopted not only in the smaller capacity models, but also in the larger capacity models. This new system resolves the opposing factors between larger output necessity and compact­ness.
Product level advantages
More powerful motor can be used without increasing size.
Wide control range offers a higher performance and operability.
Reduced maintenance cost as the needs for servicing motor brushes and contactors are eliminated.

AC power system as compared with DC power system
In the DC power system the controller will chop the battery current in repetition and control the frequency cycles of ON and OFF. The motor performance will change in proportion with the frequency cycles between ON and OFF, thereby the inching at start to the max. performance is controlled.
The AC power system in the new models includes a controller that transforms the battery current into a three­phase alternating current. The motor power is controlled by changing the sinusoidal waveform (frequency, amplitude, etc.) of the three-phase alternating current. Motor drive voltage, motor construction, and controller details differ between DC and AC power systems, as follows:

Power keep function
(Functions in power mode: P, standard mode: S)
Power keep function using the benefit of AC power system further lengthen the operation hours epochally. With conventional electric powered forklift trucks, the vehicle performance decreases gradually as the battery level goes low. The power keep function adopted to new models takes advantage of the increased controllability provided by the AC system to keep the vehicle performance even when the battery level has become low. With this power keep function, the maximum operating hours have increased by 25%, and the number of work cycles that can be completed without the operator noticing a decline in performance has also increased by 25%. New power keep function offers a significant and essential improvement in the material handling efficiency. (See page 2-2 for further detail.)

Power select function
Using the power select function, the operator can select a desirable power mode. Even though the conventional models also had a power selection switch, it only produced a small difference in the acceleration. New models use an AC motor instead of a DC motor. Since and AC motor is simpler and smaller, it becomes possible to install a motor that produces an output higher than that of a conventional DC motor. In addition, the operator can select appropriate mode from the following power modes simply by operating a switch.
• High power mode
: The most active mode with the quickest cycle-time
<H mode>
• Power mode
: The highest efficiency mode with quick cycle time and long operation hour
<P mode>
• Standard mode
: The longest operation hour mode with the performance equivalent to MFRA
<S mode>
In order to further satisfy the individual customer, a power select function has been provided. The power select function enables the operator to select one from six power modes, including H, P and S modes, for traveling. The operator can select H mode for operations requiring power and high performance. Select S mode for long time operations, providing the operator with optimum performance to suit the operator’s needs and greatly enhance efficiency.

The following particular items are inherent to the conventional electric powered models.
Supplying distilled water to the battery Material handling motor brush replacement Material handling motor contactor replacement Traveling motor brush replacement
Traveling motor contactor replacement The new 7FBMF model eliminates the need for brush and contactor replacement because the new AC motor does not have brushes and the new AC controller does not have contactors. The average customer can benefit from this by an annual cost savings of 69% for maintenance expenditures.

Taking advantage of the wider control range of the AC power system, a regenerative system is adopted. The AC induction motor generates a braking force when the vehicle is traveling with the accelerator pedal at rest. Also the electromotive force generated in the AC motor, while the accelerator pedal is released, converts the braking effect energy into electrical energy that is sent to the battery. This regenerative system increases the operation hours. At the same time, the regenerative system improves the traveling feel because it allows the operator to use less brake pedal force to slow the truck down. Further­more, the regenerative system reduces load on the brake system, slowing down brake lining wear and decreas­ing the brake maintenance costs.
1-13
Stabilizing features
The world-first System of Active Stability (SAS), adopted by the 7FB series models, is available for the new mod­els, too. Using the SAS the new models achieve the stability level equivalent to that achieved by the 7FB series models. The following outlines the SAS. For more details of the SAS option, refer to Section 11 “SAS”.
Stability feature Outline
Rear stabilizer (swing lock) The rear wheel swing mechanism is locked at high lift-heights and
heavy loads, and during a quick turn to obtain a better ground grip force from all four wheels.
Mast function control
Front tilt angle control The front tilt angle is smaller at high heights and heavy loads;
greater at low heights and light loads.
Rear tilt speed control The rear tilt speed is slower at high heights and faster at low
heights.
Key-lift interlock The lift lever cannot function by inadvertent contact.
Automatic fork leveling control A push on a control button followed by a front tilt operation tilts the
mast until the forks are horizontal.
Improvement on operability
1. Mini lever The hydraulic control levers are displaced to the arm rest fore-front and optimal length, and spacing are given on basis of human engineering. An operator can manipulate the control lever with a hand on the arm rest. Fine operation adjustment can be achieved with the display. The control lever position is ad­justable vertically as well as to lengthwise. Pleasant material handling operation with less fatigue can be ensured.
1-14
Anti-rollback
The anti-rollback function is provided to prevent the truck from rolling down on a slope. This is realized by making use of the combined features of the drive motor electric brake and the parking brake. Restarting can be done smoothly without rolling down.
Model line-up
The model line-up has been widened by the development to 3.5 ~ 5 ton class new model ranges; besides, the
1.8 ton model is added onto the 1 ~ 3 ton classes to meet with varied needs from the markets.

MAIN CONTROLLERS
General
AC system
The AC motor drive system controller has been provided with:
• Microcomputer-assisted travel inverter control (converts DC to three-phase AC)
• CAN (Controller Area Network) communication function between main controller and traveling/material han­dling controller.
• Communication function between multiple display and SAS controller.
This is a multi-functional controller with advanced electronics technology.
The controller offers the power select function and power keep function that take full advantage of the AC power system.
Power select function: Allows the operator to select from three traveling modes, H (High power) mode, P (Pow­er) mode, and S (Standard) mode. Power keep function: Maintains a high performance level even when the battery level becomes low and in­creases stress-free operation hours. (Available when P or S mode is selected.)
AC motor maximum output

Torque
DC power system output characteristics (DC motor maximum output)
Revolution
Compared to the DC motor, the AC motor has higher output and a range of output characteris­tics is obtainable from the increased output.
Torque
When the battery is discharged, the AC motor provides output characteristics closer to those of a fully charged battery than a DC motor does.
AC and DC power system output characteristics with fully charged battery
AC power system output characteristics with discharged battery
DC power system output characteristics with discharged battery
Revolution
Compared with a DC motor of an equivalent size, an AC motor has a higher output. The output characteristics of an AC motor are determined by the amplitude and frequency of the alternating cur­rent output by the controller. The controller has a map stored in its memory of the optimum combinations of the current and frequency. Using these, the optimum output characteristics can be obtained for all conditions. When the power selection switch is operated, the controller switches the map and changes the output characteristics. The power select function thus enables the output characteristics to be changed in accordance with the vehicle usage conditions.
Power keep function
With a DC power system, the output characteristics are determined by the controller output voltage. The maxi­mum output, therefore, is the output from the motor when the battery voltage is fully applied (chopper duty 100%). The output will decrease with the battery voltage as the battery is discharged. With an AC power system, however, it is possible to maintain a high performance even when the battery level becomes low because the combination of the amplitude and frequency of the alternating current is changed as the battery level goes low.

1. Regenerative system (accelerator off) When the vehicle travels with the accelerator off, a braking force produced by the motor generates electricity, which is retrieved by the battery. The working of the regenerative system extends the available operation hours and the service life of brake linings. At the same time, the regenerative system improves the travel speed controllability and stability because it allows the operator to use the soft braking force exerted by the motor. Even if the direction lever is at the neutral position, the regenerative system will function when the accelerator is off.
2-5
2. Regenerative system (brake pedal depressed) Regenerative system is operated when the brake pedal is depressed as well, which allows to extend the available operation hours and the service life of brake lining. Even if the direction is at the neutral position, the regenerative system will function when the brake pedal is depressed.
3. Regenerative system (switch back) The switch back operation (It means the directional change during traveling) also regenerate electricity like the previous model. Furthermore the AC controller in the new model has no contactor for traveling so that the switch back operates smoother than before.
4. Power select function Three traveling and material handling modes are available from a selection switch on the multiple display: H (high power) mode, P (power) mode, and S (standard) mode.
5. Advanced power select function (option) The advanced power select function allows the operator to select a traveling power mode and a material han­dling power mode independently from each other. It also allows the operator to define a mode other than H, P, and S.
6. Power keep function The power keep function maintains the vehicle performance at a high level even when the battery level is low. With the new models, stress-free operation hours for a battery charged have increased. (The power keep function is available only when the operator selects P or S mode.)
7. Auto-off system If the operator leaves the vehicle with the key switch ON, the auto-off system forcibly shuts down the con­troller (equivalent to key switch OFF) after a preset period to prevent wasteful expenditure of energy. To re­start the vehicle, turn the key switch OFF and then ON.

8. Seat switch The seat switch does not allow the vehicle to travel as well as any material handling to operate by the mini­levers unless someone is on the operator's seat.
9. Anti-rollback function The anti-rollback function makes it easy to start the vehicle on an inclined surface. This function is achieved by controlling both the drive motor and the brake system.
10. 2-speed travel speed control The 2-speed travel speed control switch sets a speed limit. The set value is adjustable by a switch on the multiple display.
11. Thermal Protector Overheat warning: Temperature in the controllers and motors are monitored by temperature sensors. If an abnormally high tem­perature is detected, the controller output is reduced to prevent overheating. The display will warn the oper­ator.

12. Battery level computation The controller monitors decrease in the battery voltage, computes the remaining capacity, and displays it as the current battery level.
13. Diagnostic function The diagnostic function can detect abnormalities in the traveling controller and the material handling control­ler, operation mechanisms such as the accelerator, and sensors. When an abnormality is detected, the di­agnostic function outputs a diagnostic code and takes the appropriate measure.
14. Analyzer function The multiple display has an analyzer mode that can be used for troubleshooting or for testing operation mechanisms and motor drivers.
15. Over-discharge warning function When the remaining capacity level reaches a specified level, the multiple display shows a warning and the load handling operation is restricted. This will protect the battery and will urge the operator to charge the battery. It is possible to release this restriction temporarily by turning the key switch off at once before resetting as emergency measures.
16. Return-to-neutral function If the operator turns the key switch ON with the direction lever at the forward or reverse position or with the accelerator pedal depressed, the vehicle will not start. The operator has to return the direction lever and ac­celerator pedal to their neutral positions once in order to allow it to restart.
17. Parking brake ON warning The buzzer sounds when the operator attempt to start the truck with the parking brake switch turned ON.
18. Parking brake OFF warning The buzzer sounds to warn the operator when moving from the drive seat without the parking brake switch turned on.
19. Mini-lever control Based on operation signals of the mini-lever, the main controller controls material handling operation by con­trolling solenoid valves and the material handling controller.

DRIVE MOTOR
General
1. The new models use a newly developed AC induction motor as the drive motor. Being compact, powerful, and maintenance-free, the new motor has ideal characteristics for a motor used in a battery-powered forklift truck.
2. Since the new motor is so compact, it provided enough space under the floor to install the battery. With the battery installed under the floor, the new models incorporate improvements in the ease of getting on and off of the vehicle and operator comfort.
3. The new motor is maintenance-free; it does not have brushes that have to be serviced.

Drive motor characteristic
The newly developed AC induction motor characteristics are as follows:
• The motor is directly installed to the drive unit case (semi-built-in structure). Consequently, the drive motor as-
sembly is very compact.
• Optimized motor core form and coils have improved the motor efficiency.
• High-precision rpm sensors have been adopted to directly detect revolving speed, realizing power selection
function, power keep function and other fine-textured functions.
• The motor temperature detection sensor has been adopted to alert the controller and prevent the motor from
overheating during overloaded operation.
Note: The truck performance may go down temporarily under the severe use condition such as contin-
uous operation with a heavy load. The performance decline at the time is not at all abnormal since it has been so arranged that the controller and the motor can be prevented from overheating. The temperature sensors incorporated in the controllers as well as the motors detect the temper­ature rise, and the control by which current supply toward the motors has undergone restriction will take place. On the occasion the monitoring display shows where subjected to overheat. In the event of the overheat indication, wait the truck operation for a while until the display indi­cation has gone away.

Structure and principle of AC induction motor
AC induction motor has no brushes, commutator and the sliding portion as opposed to the conventional DC mo­tor.
Consequently it has the following characteristics:
1. For the same output, the motor dimensions can be reduced by the portion L for the brushes and commutator.
2. For the same motor dimensions, core dimensions can be increased by the portion L, subsequently increasing the output.
3. Smaller number of parts and no sliding portion make the motor highly reliable.
An optimum AC induction motor has been developed for new models by incorporating these characteristics.

A rotor assembly consists of a number of identical aluminum conductor bars sunk into slots in a laminated steel core, and the end rings that combine both ends of the conductor bars on the sides of the core as shown. Since the bars and the end rings form like a cage for a squirrel or mouse, it is called a cage rotor.

Operational sequence
1. The current flows in a fixed direction in the field winding in the figure. Magnetic field is produced around the field winding in the illustrated direction according to the right-hand rule*, and magnetic poles (N-pole and S­pole) are generated.
2. Now suppose that the magnetic poles are rotated clockwise. Then the bar of the rotor is considered to be rotated to the counterclockwise direction.
3. Now, according to the Fleming’s right-hand rule*, electro motive force is generated to the bar of the rotor in the illustrated direction.
4. Because of the electro motive force generated to the bar of the rotor, a clockwise force is generated to the bar according to Fleming’s left-hand rule.*
5. Thus rotational torque is generated by electromagnetic force. The rotating speed of rotor is slightly slower than the revolution of the field pole.

6. Actually, the field winding on the periphery is not moving. Sine wave from each phase of the three-phase alternating current produces rotating magnetic field, generating torque to the rotor.

Operating principle of motor
Before explaining the operating principle of motor, Ampere’s right thread rule and Fleming’s rule will be ex­plained.
1. Right handed screw rule Extend the thumb of the right hand and close the fingers. If you point the thumb in the direction of current flow as illustrated, the magnetic field is produced at right angle to the current direction and in the direction of the closed fingers.

2. Fleming’s right-hand rule Arrange for a fixed object on which a linear object can freely move as shown. In this state, when the magnetic field is pro­duced in the illustrated direction, moving the linear object in the illustrated direction produces current. The direction of current is as illustrated:
3. Fleming’s left-hand rule Arrange for a fixed object on which a linear object can freely move as shown. In this state, when the magnetic field is pro­duced in the illustrated direction, current flowing in the fixed ob­ject causes a force acts on the linear object in the illustrated direction.

Previous models
4-axes, 3-stages speed reduction
2. The parking brake has been set up on the drive motor shaft due to the adoption of the wet brake.
3. New models like the previous models, the drive motor has been installed to the drive unit in “Semi-built-in structure”, on a parallel to the front axle.
4. New models, like the previous models, use the liquid gasket (FIPG) to obtain high sealing effect on the drive unit housing.
5. As the lubricant, use the gear oil suitable for the wet brake.
Note: Use gear oil only TOYOTA specified:
SHELL DONAX TD
6. New models like the previous models, helical gear having high transmitting efficiency has been adopted to all the gears.

Note:
1. Lubricant for brake For the lubrication of the brake discs as well as for the drive gearing, the same oil are used, since the wet brake discs are dipped in gear oil. Only TOYOTA specified oil must be used.
TOYOTA Specified oil: SHELL DONAX TD
It must be strictly forbidden to use the oil other than those specified by TOYOTA or oil mixed with another since it will give the adverse effect, such as the brake mal-function and the noise occurrence.
2. Service for brake life In case that the brake has become ineffective or noise should arise, the deterioration of the gear oil and the brake discs can be suspected as the possible causes. At the time, the gear oil should be renewed at first. If it is still ineffective, wearing down of the brake discs can be considered. Then the brake discs should be renewed together with the gear oil.
3. Washing It must be strictly avoided to splash water round the breather (or bleed) plug while washing the truck since water will penetrate into gear oil through the breather plug.

Function
• Newly designed parking brake system differs from the previous system in that the parking brake force arises when the brake discs are compressed on the motor shaft through the piston pressed by the conical disc springs.
• On turning the parking switch ON, the solenoid valve releases oil in the chamber ‘A’ so that the force of the conical disc springs will apply the brake.
• On turning the parking switch OFF, pressurized oil is fed to the brake housing from the PS pump through the solenoid valve. Then the conical disc springs are compressed throgh hydraulic pressure so that the brake will be released.

Parking brake switch
• The parking brake system is actuated by the electrical selector switch as illustrated:
Turn it to the right: Parking brake on
Turn it to the left: Parking brake release
Note:
• Always stop the truck and turn on the parking brake switch (turn to the right) to engage the parking brake before getting off the vehicle. Check to confirm that the parking brake is engaged.
• Never turn off the key switch unnecessarily while traveling, because it will cause the truck a sudden stop with a shock.
• Never pull off the battery plug while traveling (except in case of emergency), because it will cause the truck a sudden stop with a shock.
• It is impossible to release the parking brake if the power steering pump should stop supplying the parking brake with pressurized oil; therefore, in case that the traction of the truck is in urgent need, the parking brake cover plug should be removed to release the parking brake manually with a specified tool (bolt).

Function
1. The parking brake will be released when it receives oil pressure from the brake change valve. When it does not take oil pressure, it becomes the condition that a parking brake piston is pressed by the cone spring, and the parking brake is effective.
2. The brake change valve changes an oil way to the parking brake by the solenoid valve. Solenoid ON: The parking brake is released as it makes the oil way to the parking brake opened. Solenoid OFF: The parking brake is applied as it makes the oil way to the parking brake closed.
3. The motor (The PS motor for 1.6 to 3.5 tons models and the pump motor for 4.0 to 5.0 tons models) starts driving when both the key switch and the direction switch are turned on. Then, oil pressure will arise from the oil pump directly connected to the motor.
4. The main control controller controls the solenoid valve by the signals from each switch.
Note: The traveling speed sensor which detects the traveling condition of the vehicle also has relation
to the parking brake system through the traveling controller.
5-16
5. To try to travel the vehicle makes the parking brake released. When all the following conditions are satisfied, the parking brake is released by turning on the solenoid valve.
• Turning on the key switch
• Turning on the seat switch (The seated condition)
• Shifting the parking switch left (Release side)
• Turning on the direction switch (Forward or Reverse)
• Switching on the accelerator (Depressing the accelerator pedal) In reverse, either of the following manipulation makes the parking brake operated by changing the solenoid from ON to OFF.
• Turning off the key switch
• Shifting the parking switch right (Parking side) When the switch other than mentioned above is turned off, the parking brake is not actuated at once but con­trolled as the following items 6, 7 and 8.
6. When a foot is left from the accelerator pedal during traveling, the parking brake is applied from 10 seconds later after an electric brake acts and the vehicle stops completely. And, it is the same when the direction lever is made a neutral position during traveling.
7. Brake control on a slope If the accelerator pedal is released with the neutral direction lever position after the vehicle stops on the slope once, the electric brake (the regenerative brake) works for 10 seconds to prevent the truck from going down, and then it makes the parking brake acted in place of the electric brake.
8. If the seat switch is turned off during traveling, the controller considers the condition as an emergent situation, and it makes the parking brake acted by changing the solenoid valve from ON to OFF as soon as the vehicle stops by the electric brake.

BRAKE PEDAL
• 1.6 ~ 3.5 ton New models use the pendent type brake pedal in place of the step down type brake pedal on the previous models.
• 4.0 ~ 5.0 ton: The pendent type brake pedal and the double link mechanism have been adopted.
Regenerative sensor
The limit switch has been adopted for reliability as that of the previous model, and sensing ability has been im­proved. When the readjustment is required for the regenerative brake, service accessibility is good.

Principle of EHPS (Electronically controlled full-Hydraulic Power Steering)
1. The steering sensor will defect the steering wheel revolution speed without mechanical contact while the op­erator rotating the steering wheel.
2. In the meantime, the detected speed is turned into electronic pulse signals and being sent to the controller.
3. The controller will adjust the current being supplied to the power steering motor corresponding to the pulse signals.
4. Thus the adequate power steering motor speed in response to the steering manipulation can be obtained.

1. When the truck is running straight forward (or when the steering wheel is not in operation), the power steering valve absorbs the reaction from the tires before it is transmitted to the steering wheel.
2. When the battery voltage is stopped, the power steering valve works instead of the pump by making the man­ual steering circuitry.

LOAD HANDLING LEVER (MINI-LEVER)
1) The structure of mini-lever Mini lever is available as standard to meet the demand of European market.
The operation stroke has been made smaller and operating force has been decreased by changing the position of the lever from over cowl to right front of the seat. Operability is improved and operator’s fatigue with the lever operation is reduced.
It is easy to replace the vehicle from previous model with new model because the lever is independent forward­back single axis lever that is the same as manual lever cowl position of previous model.
Fork automatic leveling control switch is located on back of tilt lever. Once the button is pushed, the movement condition of the button is held by the locking mechanism of inside switch, and the fork automatic leveling function is effective. When the button is pushed again, the lock is released and the fork automatic leveling control function is canceled. (Refer to page 11-10 Active mast function controller for detail function.)
Lever position is adjustable in forward-back direction. Loosen the knob that fix lever box, and set the lever box at the position that operator prefer, and tighten the knob to fix the lever box.
Guard is installed around the lever.
Load handling operation is prohibited when operator leaves the seat.
