General Instructions

2.3 ABOUT THE CFW-11

The CFW-11 frequency inverter is a high performance product designed for speed and torque control of three-phase induction motors. The main characteristic of this product is the "Vectrue" technology, which has the following advantages:

Scalar control (V/f), VVW or vector control programmable in the same product.

The vector control may be programmed as "sensorless" (which means standard motors without using encoders)

or as "vector control" with the use of an encoder.

The "sensorless" control allows high torque and fast response, even in very low speeds or at the starting.

The "vector with encoder" control allows high speed precision for the whole speed range (even with a standstill

motor).

"Optimal Braking" function for the vector control, allowing the controlled braking of the motor and avoiding

the use of the braking resistor in some applications.

"Self-Tuning" feature for vector control. It allows the automatic adjustment of the regulators and control

parameters from the identification (also automatic) of the motor parameters and load.

3.1.2 Mounting Considerations

Consult the inverter weight at the Table 8.1 on page 8-2, Table 8.2 on page 8-3, Table 8.3 on page 8-4 and Table 8.4 on page 8-5.

Mount the inverter in the upright position on a flat and vertical surface.

External dimensions and fixing holes position according to the Figure 3.1 on page 3-3, Figure 3.2 on page

3-4 and Figure 3.2 on page 3-4. Refer to the Section 8.5 MECHANICAL DATA on page 8-9, for more

details.

First mark the mounting points and drill the mouting holes. Then, position the inverter and firmly tighten the screws in all four corners to secure the inverter.

Minimum mounting clearances requirements for proper cooling air circulation are specified in Figure 3.3 on page

3-5, Figure 3.5 on page 3-9 and Figure 3.4 on page 3-6.

Inverters of frame sizes B and C can be arranged side-by-side with no clearance required between them. In this case, the top cover must be removed as shown in Figure 3.3 on page 3-5.

Do not install heat sensitive components right above the inverter.

ATTENTION!

When arranging two or more inverters vertically, respect the minimum clearance A + B (Figure 3.3 on

page 3-5, Figure 3.5 on page 3-9 and Figure 3.4 on page 3-6) and provide an air deflecting

plate so that the heat rising up from the bottom inverter does not affect the top inverter.

ATTENTION!

3.1.3 Cabinet Mounting

There are two possibilities for mounting the inverter: through the wall mounting or flange mounting (the heatsink is mounted outside the cabinet and the cooling air of the power module is kept outside the enclosure). The following information shall be considered in these cases:

Surface Mounting:

Provide adequate exhaustion so that the internal cabinet temperature is kept within the allowable operating

range of the inverter.

The power dissipated by the inverter at its rated condition, as specified in Table 8.1 on page 8-2 to Table

8.4 on page 8-5 "Dissipated power in Watts - through the wall mounting".

The cooling air flow requirements, as shown in Table 3.1 on page 3-8.

The position and diameter of the mounting holes, according to Figure 3.1 on page 3-3, Figure 3.2 on

page 3-4 and Figure 3.2 on page 3-4.

Flange Mounting:

Frame Sizes B, C and D:

The losses specified in Table 8.1 on page 8-2 and Table 8.3 on page 8-4 "Dissipated power in Watts -

flange mounting" will be dissipated inside the cabinet. The remaining losses (power module) will be dissipated through the vents.

The mounting supports shall be removed and repositioned as illustrated in Figure 3.5 on page 3-9.

The portion of the inverter that is located outside the cabinet is rated IP54. Provide an adequate gasket for

the cabinet opening to ensure that the enclosure rating is maintained. Example: silicone gasket.

Mounting surface opening dimensions and position/diameter of the mounting holes, as shown in Figure 3.1

on page 3-3.

Frame Size E:

The losses specified in Table 8.1 on page 8-2 and Table 8.3 on page 8-4 "Dissipated power in Watts -

flange mounting" will be dissipated inside the cabinet. The remaining losses (power module) will be dissipated through the vents.

The inverter securing supports (position I of Figure 2.5 on page 2-9) and the hoisting eyes (position J of

Figure 2.5 on page 2-9) must be removed and repositioned according to the Figure 3.6 on page 3-10

and Figure 3.7 on page 3-10.

For models 53 A, 63 A, 80 A and 107 A, the portion of the inverter that is located outside the cabinet

is rated IP54. Provide an adequate gasket for the cabinet opening to ensure that the enclosure rating is maintained. Example: silicone gasket.

Installation and Connection

Mounting surface opening dimensions and position/diameter of the mounting holes, as shown in Figure 3.2

on page 3-4.

Frame Sizes F, G and H:

ATTENTION!

The part of the inverter that stays outside the cabinet is rated IP20.

The power specified in Table 8.1 on page 8-2 to Table 8.4 on page 8-5 under "Dissipated power in

Watts - flange mounting" will be dissipated inside the cabinet. Use Table 8.1 on page 8-2 and Table 8.3

on page 8-4 for inverters with AC power supply and Table 8.2 on page 8-3 and Table 8.4 on page 8-5 for inverters with DC power supply. The other losses (power modules) will be dissipated at the external

ventilation duct.

The inverter mounting supports and the hoisting eyes must be removed. Refer to the Figure 3.8 on page

3-11, positions I and J.

Dimensions of the flange-mounting opening and the diameters of the securing holes must be according to

3.2.2 Power/Grounding Wiring and Fuses

ATTENTION!

Use proper cable lugs for the power and grounding connection cables.

ATTENTION!

Sensitive equipment such as PLCs, temperature controllers, and thermal couples shall be kept at a minimum distance of 0.25 m (9.84 in) from the frequency inverter and from the cables that connect the inverter to the motor.

DANGER!

Wrong cable connection:

- The inverter will be damaged if the power supply is connected to the output terminals (U/T1, V/T2, or W/T3).

- Check all the connections before powering up the inverter.

- When replacing an existing inverter by a CFW-11, check if the installation and wiring is according to the instructions listed in this manual.

DANGER!

Mauvaise connexion des câbles:

- Le variateur sera endommagé si l’alimentation d’entrée est connectée aux bornes de sortie (U/T1, V/T2 ou W/T3).

- Vérifier toutes les connexions avant de mettre le variateur sous tension.

- En cas de remplacement d’un variateur existant par un CFW-11, vérifier si l’installation et le câblage sont conformes aux instructions figurant dans ce manuel.

ATTENTION!

Residual Current Device (RCD):

- When installing an RCD to guard against electrical shock, only devices with a trip current of 300 mA should be used on the supply side of the inverter.

- Depending on the installation (motor cable length, cable type, multimotor configuration, etc.), RCD nuisance trips may occur. Contact the RCD manufacturer for selecting the most appropriate device to be used with inverters.

NOTE!

The wire gauges listed in Table 3.2 on page 3-21 are orientative values. Installation conditions and the maximum permitted voltage drop must be considered for the proper wiring sizing.

3-20 | CFW-11

Installation and Connection

Input fuses:

Use High Speed Fuses at the input for the protection of the inverter rectifier and wiring refer to Table 3.2 on

page 3-21 for selecting the appropriate fuse rating (I2t must be equal to or less than indicated in Table 3.2 on page 3-21, consider the cold (and not the fusion) current extinction value).

In order to meet UL requirements, use class J fuses at the inverter supply with a current not higher than the

values of Table 3.2 on page 3-21.

Optionally, slow blow fuses can be used at the input they must be sized for 1.2 x the inverter rated input

current. In this case, the installation is protected against short-circuit, but not the inverter input rectifier. This may result in major damage to the inverter in the event of an internal component failure.

Table 3.2 - Recommended wire size/fuses - use copper wire (75 ºC (167 ºF)) - frame size B, 500 to 600 Vac supply voltage

∆V = Percentage voltage drop.

VLL = Inverter supply line voltage. fR = Line frequency. I = Reactor current. Consider half the inverter input current for each reactor and an unbalance 15 %. For example, in model 1141 A, the maximum current of each reactor is 1.15 (1141/2) = 656 A. (2) For frame size H models 758 A and 804 A it's necessary two line reactors with 3 % voltage drop minimum. Consider a half of inverter input current for each reactor and an unbalance of 15 %. For example in model 758 A, the maximum current in each reactor is 1.15 (758/2) = 436 A).

3.2.3.1 Input Connections

DANGER!

Provide a disconnect device for the input power supply of the inverter. This device shall disconnect the input power supply for the inverter when needed (for instance, during servicing).

DANGER!

Montez un dispositif de coupure sur l'alimentation du variateur. Ce composant déconnecte l'alimentation du variateur si cela est nécessaire (ex. pendant l'entretien et la maintenance).

3-34 | CFW-11

Installation and Connection

ATTENTION!

A contactor or another device that frequently disconnects and reapplies the AC supply to the inverter, in order to start and stop the motor, may cause damage to the inverter power section. The drive is designed to use control signals for starting and stopping the motor. If used for that purpose, the input device must not exceed one operation per minute; otherwise, the inverter may be damaged.

ATTENTION!

The power supply that feeds the inverter shall have a grounded neutral. In case of IT networks, follow the instructions described in Item 3.2.3.1.2 IT Networks on page 3-35.

NOTE!

The input power supply voltage shall be compatible with the inverter rated voltage.

NOTE!

Power factor correction capacitors are not needed at the inverter input (R, S, T) and shall not be installed at the output of the inverter (U, V, W).

3.2.3.1.1 AC Power Supply Considerations

Suitable for use in circuits capable of delivering not more than 65,000 Arms symmetrical at 240 V or 480 V for

maximum 480 V rated models, and 14,000 Arms symmetrical at 600 V for maximum 690 V rated models, when protected by inverse-time circuit breakers rated for the input voltage of the drive and 130 % of the full-load motor output current rating.

3.2.3.1.2 IT Networks

ATTENTION!

For using the inverter CFW11...T5 or T6 in IT networks (neutral conductor not grounded or grounded via high ohmic value resistor) or in corner-grounded delta networks, the following modifications are required in the connections of some internal components to ground:

Frame sizes B, C and D: remove the screw as indicated in Figure 3.26 on page 3-36. Frame size E: change the position of the J1 jumper on the PRT board from (XE1) to "NC"

(XIT), according to Figure 3.27 on page 3-36.

Frame sizes F, G and H: disconnect the cable with the ring tongue lug from the ground busbar and

connect it to the isolated point on the power terminal block as shown in the Figure 3.28 on page 3-37,

Figure 3.29 on page 3-37 and Figure 3.30 on page 3-37 .

That is necessary to avoid damage to the inverter when operating with a line input shorted to ground.

Installation and Connection

NOTE!

The ground-fault protection (F074) is intended for IGBT protection and may not be activated when inverter output is shorted to ground, when fed by IT networks. External insulation monitoring devices should be used for system fault monitoring.

3.2.3.2 Dynamic Braking

NOTE!

All frame sizes B and C models do have internal braking IGBT. Models of frame sizes D and E with the codification CFW11...O...NB... and all models of frame sizes F, G and H do not have internal braking IGBT.

NOTE!

For dynamic braking with frame sizes F, G and H models use external braking module (see Item 7.2.1

Use of External Dynamic Braking Module DBW03 and DBW04 on page 7-4). For installation refer

to Figure 3.31 on page 3-39.

The braking torque that can be obtained from the frequency inverter without braking resistors varies from 10 % to 35 % of the motor rated torque.

Braking resistors shall be used to obtain higher braking torques. In this case, the energy regenerated in excess is dissipated in a resistor mounted externally to the inverter.

This type of braking is used in cases where short deceleration times are desired or when high inertia loads are driven.

The "Optimal Braking" feature may be used with the vector control mode, which eliminates in most cases the need of an external braking resistor.

NOTE!

Set P0151 and P0185 to their maximum values (1000 V for power supply voltages from 500 to 600 V; 1200 V for power supply voltage from 660 to 690 V) when using dynamic braking.

3.2.3.2.1 Sizing the Braking Resistor

The following application data shall be considered for the adequate sizing of the braking resistor:

- Desired deceleration time.

- Load inertia.

- Braking duty cycle.

In any case, the effective current value and the maximum braking current value presented in Table 3.8 on page

3-29 shall be respected.

The maximum braking current defines the minimum braking resistor value in ohms.

3-38 | CFW-11

Installation and Connection

The DC bus voltage level for the activation of the dynamic braking function is defined by parameter P0153 (dynamic braking level).

The power of the braking resistor is a function of the deceleration time, the load inertia, and the load torque.

For most applications, a braking resistor with the value in ohms indicated in Table 3.10 on page 3-40 and the power of 20 % of the rated driven motor power. Use WIRE type resistors in a ceramic support with adequate insulation voltage and capable of withstanding high instantaneous power with respect to rated power. For critical applications with very short deceleration times and high inertia loads (eg.: centrifuges) or short duration cycles, consult WEG for the adequate sizing of the braking resistor.

3.2.3.2.2 Installation of the Braking Resistor - Frame Sizes B, C, D and E

Install the braking resistor between the power terminals DC+ and BR.

Use twisted cable for the connection. Separate these cables from the signal and control cables. Size the cables according to the application, respecting the maximum and effective currents.

If the braking resistor is installed inside the inverter cabinet, consider its additional dissipated energy when sizing the cabinet ventilation.

Set parameter P0154 with the resistor value in ohms and parameter P0155 with the maximum resistor power in kW.

DANGER!

The inverter has an adjustable thermal protection for the braking resistor. The braking resistor and the braking transistor may damage if parameters P0153, P0154, and P0155 are not properly set or if the input voltage surpasses the maximum permitted value.

3-40 | CFW-11

Installation and Connection

DANGER!

Le variateur possède une protection thermique réglable pour la résistance de freinage. La résistance de freinage et le transistor de freinage peuvent être endommagés si les paramètres P0153, P0154 et P0155 ne sont pas correctement définis ou si la tension d’entrée dépasse la valeur maximale autorisée.

The thermal protection offered by the inverter, when properly set, allows the protection of the resistor in case of overload; however, this protection is not guaranteed in case of braking circuitry failure. In order to avoid any damage to the resistor or risk of fire, install a thermal relay in series with the resistor and/or a thermostat in contact with the resistor body to disconnect the input power supply of the inverter, as presented in Figure 3.32

on page 3-41.

ATTENTION!

The inverter has an electronic motor overload protection that shall be adjusted according to the driven motor. When several motors are connected to the same inverter, install individual overload relays for each motor.

CFW-11 | 3-41

Installation and Connection

ATTENTION!

The motor overload protection available in the CFW-11 is in accordance with the IEC60947-4-2 and UL508C standards, note the following information:

Trip current equal to 1.25 times the motor rated current (P0401) adjusted in the oriented start-up

menu. The maximum value for P0398 (Motor service factor) is 1.15. Parameters P0156, P0157 and P0158 (Overload current at 100 %, 50 % and 5 % of the rated

speed, respectively) are automatically adjusted when parameters P0401 (Motor Rated Current)

and/or P0406 (Motor Ventilation) are adjusted in the oriented start-up routine. If parameters

P0156, P0157 and P0158 are manually adjusted, the maximum allowed value is 1.05 x P0401.

ATTENTION!

If a disconnect switch or a contactor is installed between the inverter and the motor, never operate them with a spinning motor or with voltage at the inverter output.

The characteristics of the cable used for the inverter and motor interconnection, as well as the physical location are extremely important to avoid electromagnetic interference in other equipment and to not affect the life cycle of motor windings and motor bearings controlled by inverters.

Recommendations for the motor cables:

Unshielded Cables:

Can be used when it is not necessary to meet the European directive of electromagnetic compatibility

(2004/108/EC).

Keep motor cables away from other cables (signal cables, sensor cables, control cables, etc.), according to

Table 3.11 on page 3-43.

The emission of the cables may be reduced by installing them inside a metal conduit, which shall be grounded

at both ends.

Connect a fourth cable between the motor ground and the inverter ground.

NOTE!

The magnetic field created by the current circulation in these cables may induce current in close metal pieces, heat them, and cause additional electrical losses. Therefore, keep the three cables (U, V, W) always together.

Shielded Cables:

They are mandatory when the electromagnetic compatibility directive (2004/108/EC) shall be met, as

defined by the standard EN 61800-3 "Adjustable Speed Electrical Power Drive Systems". These cables act mainly by reducing the irradiated emission in the radio-frequency range.

SCu

In reference to the type and details of installation, follow the recommendations of IEC 60034-25 "Guide for

Design and Performance of Cage Induction Motors Specifically Designed for Converter Supply" - refer to a

summary in Figure 3.33 on page 3-43. Refer to the standard for further details and eventual modifications

related to new revisions.

Keep motor cables away from other cables (signal cables, sensor cables, control cables, etc.), according to

Table 3.11 on page 3-43.

The grounding system shall be well interconnected among the several installation locations such as the

grounding points of the motor and the inverter. Voltage difference or impedance between the several points

may cause the circulation of leakage currents among the equipment connected to the ground, resulting in

electromagnetic interference problems.

Connection of the motor cable shield to ground: make a connection with low impedance for high frequencies.

Frame sizes B and C:

There is a kit for connection of the shielding of power cables that is supplied with the inverters (except for inverters CFW11...T5O...NF...), which assembled on the bottom of the enclosure as shown in Figure 3.34 on page 3-44 and facilitates the connection of the shielding of motor and the line cable. That kit is also an acessory - PCSx-01.

3.2.4 Grounding Connections

DANGER!

Do not share the grounding wiring with other equipment that operate with high currents (e.g. high power motors, soldering machines, etc.). When installing several inverters, follow the procedures presented in Figure 3.35 on page 3-45 for the grounding connection.

DANGER!

Ne pas partager le câblage de mise à la terre avec d’autres équipements opérant avec des intensités élevées (par ex: moteurs haute puissance, postes de soudure, etc.). Lors de l’installation de plusieurs variateurs, appliquer les procédures présentées dans l’illustration Figure 3.35 à la page 3-45 pour la connexion de mise à la terre.

ATTENTION!

The neutral conductor of the network must be solidly grounded; however, this conductor must not be used to ground the inverter.

DANGER!

The inverter must be obligatorily connected to a protective ground (PE). Observe the following:

- Use a minimum wire gauge for ground connection equal to the indicated in Table 3.2 on page

3-21 to Table 3.6 on page 3-25. Conform to local regulations and/or electrical codes in case a

different wire gauge is required.

- Connect the inverter grounding connections to a ground bus bar, to a single ground point, or to a

common grounding point (impedance ≤ 10 Ω).

- To comply with IEC 61800-5-1 standard, connect the inverter to the ground by using a single conductor copper cable with a minimum wire gauge of 10 mm2, since the leakage current is greater than 3.5 mA AC.

3-44 | CFW-11

Installation and Connection

DANGER!

Le variateur doit être raccordé à une terre de protection (PE). Observer les règles suivantes:

- Utilisez la section minimale de raccordement à la terre indiquée dans les Table 3.2 à la page

3-21 à Table 3.6 à la page 3-25. Se conformer aux à la règlementation locale et/ou aux codes

de l'électricité si une autre épaisseur de fil est nécessaire.

- Connectez la masse du variateur à une barre collectrice de terre en un seul point ou à un point

commun de raccordement à la terre (impédance ≤ 10 Ω).

- Pour assurer la conformité avec la norme CEI 61800-5-1, connecter le variateur à la terre grâce à un câble en cuivre à un conducteur ayant une épaisseur de fil minimale de 10 mm², étant donné que le courant de fuite est supérieur à 3,5 mA C.A.

5. Relays, contactors, solenoids or coils of electromechanical brakes installed close to the inverter may occasionally generate interferences in the control circuitry. To eliminate this effect, RC suppressors (with AC power supply) or freewheel diodes (with DC power supply) must be connected in parallel to the coils of these devices.

3.2.6 Typical Control Connections

Control connection 1 - Run/Stop function controlled from the keypad (Local Mode).

With this control connection, it is possible to run the inverter in local mode with the factory default settings. This operation mode is recommended for first-time users, since no additional control connections are required.

For the start-up in this operation mode, please follow instructions listed in Chapter 5 FIRST TIME POWER-UP

AND START-UP on page 5-1.

Control connection 2 - 2-Wire Run/Stop function (Remote Mode).

This wiring example is valid only for the default factory settings and if the inverter is set to remote mode.

With the factory default settings, the selection of the operation mode (local/remote) is performed through the HMI key

(local mode is default). Set P0220 = 3 to change the default setting of HMI key

to remote mode.

3.3 SAFETY STOP FUNCTION

The inverters CFW11...O...Y... have the board SRBXX that implements Safety Stop function. Through this board it is possible to control two safety relays (K1 and K2) that actuate directly on the power circuit, more specifically on the IGBTs gate drivers power supply. The basic functional block diagram is shown in Figure 3.45 on page 3-55.

The safety relays guarantee that the IGBTs remain switched off when Safety Stop function is activated, even in case of an internal single failure. The position of SRBXX board and XC25 terminals (Safety Stop control terminals) on the inverter is shown in Figure 3.38 on page 3-49.

The Safety Stop function prevents the motor starting accidentally.

DANGER!

The activation of the Safety Stop function does not guarantee electrical safety of the motor terminals (they are not isolated from the power supply in this condition).

DANGER!

L'activation de la fonction d'arrêt de sécurité ne garantit pas la sécurité électrique des bornes du moteur (elles ne sont pas isolées de l'alimentation électrique dans cet état).

ATTENTION!

In case of a multiple fault in the power stage of the inverter, the motor shaft can rotate up to 360/ (number of poles) degrees even with the activation of Safety Stop function. That must be considered in the application.

NOTE!

Inverter Safety Stop function is only one component of the safety control system of a machine and/or process. When inverter and its Safety Stop function is correctly used and with other safety components, it’s possible to fulfill the requirements of standard EN 954-1 / ISO 13849-1, Category 3 (machine safety) and IEC/EN 61508, SIL2 (safety control/signaling applied to processes and systems).

Inverter Behavior

Inverter remains in STO state and does not accept commands. In order to escape this condition, it’s required to have STO1 = 1 and STO2 = 1 simultaneously

Inverter is tripped by F160 fault (Safety Stop function related fault). To escape this condition, it’s required to reset the inverter

NOTE!

Maximum delay between STO1 and STO2 signals: 100 ms (otherwise inverter will be tripped by F160 fault).

Safety Stop function takes priority over all other functions of the inverter.

This function should not be used as a control for starting and/or stopping the inverter.

vice-versa or there is a delay of more than 100 ms between one signal and the other. To solve it, correct the external circuit that generates STO1 and STO2 signals

3.3.2.3 STO Status Indication

State of the inverter is shown on the left upper side of the display and in parameter P0006.

Possible states of the inverter: ready, run (inverter enabled), undervoltage, fault, self-tuning, configuration, DC braking and STO (Safety Stop function activated).

It’s possible to set one or more digital and relay outputs of the inverter to indicate that Safety Stop function is activated (state of the inverter = STO), if the inverter is or not on a fault state and more specifically if the inverter was tripped by F160 fault (Safety Stop function fault). For that use the parameters P0275 (DO1), P0276 (DO2), P0277 (DO3), P0278 (DO4) and P0279 (DO5) according to Table 3.18 on page 3-58.

Refer to inverter programming manual for a complete list of options for parameters P0275...P0279.

3.3.2.4 Periodic Test

Safety Stop function, alternatively safety stop inputs (STO1 and STO2), must be activated at least once a year for preventive maintenance purposes. Inverter power supply must be switched off and then on again before carrying out this preventive maintenance. If during testing the power supply to the motor is not switched off, safety integrity is no longer assured for the Safety Stop function. The drive must therefore be replaced to ensure the operational safety of the machine or of the system process.

Installation and Connection

Circuit operation of SS1 function from Figure 3.46 on page 3-59:

In this case, when the activation command is given to the external safety relay, safety relay opens inverter DI2 signal (via terminals 23 to 24) and motor is decelerated first by the inverter (via deceleration ramp). When the time delay set at the external safety relay expires (this delay must be higher than required time to stop the motor, taking into account deceleration time set on the inverter and inertia of the motor load), the safety relay delayed contacts (terminals 47 to 48 and 57 to 58) opens inverter STO1 and STO2 signals and the inverter Safety Stop function is activated. The motor stops according to category 1 (SS1) of standard IEC/EN 60204-1.

In order to drive the motor again, it is required to apply STO1 and STO2 signals again (to close terminals 13 to 23 and 23 to 24) and apply a pulse on inverter DI1 input (START).

Installation:

The keypad can be installed or removed from the inverter with or without AC power applied to the inverter.

The HMI supplied with the product can also be used for remote command of the inverter. In this case, use a

cable with male and female D-Sub9 (DB-9) connectors wired pin to pin (mouse extension type) or a market standard Null-Modem cable Maximum length of 10 m (33 ft). It is recommended the use of the M3 x 5.8 standoffs supplied with the product. Recommended torque: 0.5 Nm (4.5 lbf in).

When power is applied to the inverter, the display automatically enters the monitoring mode. Figure 4.3 on

page 4-3 presents the monitoring screen displayed for the factory default settings. By properly setting specific

inverter parameters, other variables can be displayed in the monitoring mode or the value of a parameter can be displayed using bar graphs or with larger characters as presented in Figure 4.3 on page 4-3.
