WARNING

Do not touch circuit components until main input power has been turned OFF. Status indicator LEDs and Digital Operator display will be extinguished when the DC bus voltage is below 50 VDC. Wait at least one additional minute.

Do not connect or disconnect wires and connectors while the main input power is turned on.

CAUTION

The drive leaves the factory with parameters initialized for 2-Wire control (when using external Run/Stop signals). Before using the initialization function of constant n01 , know your control wiring configuration:

10 = Factory 2-Wire Control Initialization (Maintained RUN Contact) 11 = Factory 3-Wire Control Initialization (Momentary START/STOP Contact)

Entering either Initialization code resets all parameters to factory settings, and automatically returns parameter n001 setting to “ 1 ”. If the drive is connected for 3-Wire control and this parameter is set to “ 10 ” (2-Wire Control Initialization), the motor may run in reverse direction WITHOUT A RUN COMMAND APPLIED. Equipment damage or personal injury may result.

- ii -

CAUTION

Parameter n10 must be set to proper motor voltage.

CAUTION

Always ground the drive using its ground terminal ( ) (near the main circuit output terminals). See paragraph 1.4A,“Grounding”.

Never connect main circuit output terminals T1 (U),T2 (V) & T3 (W) to AC main circuit power supply.

CAUTION

When drive is programmed for auto-restart ( n48 = " 1 " thru " 10 "), the motor may restart unexpectedly — personal injury may result.

IMPORTANT

Wiring should be performed only by qualified personnel.

Always ground the drive using ground terminal ( ). See paragraph 1.4C, “Grounding”.

Verify that the rated voltage of the drive matches the voltage of the incoming power.

Never connect main circuit output terminals T1, T2, and T3 to AC main circuit power supply.

All parameters have been factory set. Do not change their settings unnecessarily.

Do not perform a “HIPOT” or withstand voltage test on any part of the drive. Equipment uses semiconductors and is vulnerable to high voltage.

The Control PCB employs CMOS ICs which are easily damaged by static electricity. Use proper electrostatic discharge (ESD) procedures when handling the Control PCB. Never touch the printed control board (PCB) while the main input power is turned on.

Any modification of the product by the user is not the responsibility of Yaskawa, and will void the warranty.

Do not remove the Digital Operator or change dipswitch SW8 or rotary switch SW7 unless the main input power is turned OFF..

This drive is not suitable for use on a circuit capable of delivering more than 18,000 RMS symmetrical amperes at either 250 volts maximum or 480 volts maximum.

J7 Simplified Startup Procedure

- iii -

This procedure is a simplified step by step guide to installing, programming, and using the J7

drive. It highlights several common installation configurations. Detailed information on all features of this drive can be found in the Technical Manual.

INSTALLATION

1. Be certain your input voltage source, motor and drive nameplates are all marked either 230V or 460V. Other voltages can be used, but require additional programming, see

technical manual. CAUTION: Verify that the input voltage matches the Drive’s

nameplate BEFORE applying power or severe damage will result.

2. Mount Drive on a vertical surface with adequate space for air circulation (4.7” above and

below, 1.2” on each side).

3. Remove front cover using the screw in the lower left corner, then connect power and ground wires as shown.

CAUTION: BE CERTAIN YOU CONNECT INPUT POWER TO TERMINALS L1, L2, AND L3 ONLY, OR SERIOUS DAMAGE WILL RESULT. CONNECT MOTOR TO TERMINALS T1, T2, AND T3 ONLY.

4. Replace cover and apply input power – digital operator shows “0.0”; The FREF LED is on and the RUN LED is flashing. Press the DSPL key until the LO/RE LED is on. Press the UP ARROW button until the display shows “Lo”, then press the DSPL button until the FREF LED is on. Rotate the potentiometer on the front of the digital operator until the display shows “6.0”. Press the RUN button and note the direction of motor rotation. If rotation is incorrect, remove power, wait for the display lights to go out, then switch wires between terminals T1 and T2. Replace the front cover and apply input power.

- iv -

5. Digital Operator The DSPL button cycles through all of the quick start LEDs.

To access a parameter, press the DSPL button until the PRGM LED is on. Use the UP and DOWN keys until the desired parameter number is displayed, then press ENTER. Use the UP and DOWN keys to adjust the value then press ENTER then DSPL.

Before the drive will accept a RUN command, one of the following LEDs must be on: FREF, FOUT, IOUT, MNTR, or F/R. For more specific information on the digital operator, see the Tech. Manual, Section 4.

6. Choose a configuration from Table 1 below. Each example listed below contains a control wiring diagram, operation explanation, and all necessary programming. The

drive can be controlled in many more ways than is described in these examples.

With this method, remote pushbuttons start and stop the drive and the reference comes from a speed control (potentiometer).

7. Control Terminal Wiring – Remove power and wait for all LEDs to go out before making control terminal connections. Control wiring should be sized 16 to 20 AWG. Control wiring should be shielded, with the shield wire connected to the ground terminal

, which is located towards the left

side of the aluminum heat sink.

Example 1: Sequence & Reference From The Digital Operator

- v -

When the Drive is set up with the sequence and the reference coming from the digital operator, it is in “Local” control. Local control is often used during startup to verify motor operation, rotation, etc. The Drive can be

temporarily placed in “Local” control simply by using the LO/RE quick start LED. If power is removed and then

restored, the Drive will come up in the “Remote” mode. The Drive can be programmed so that even if power is lost, the drive will come up in the local mode (see Table

2 below).

OPERATION:

•

The frequency reference comes from the digital operator pot.

•

The drive can be started by pressing the

•

The drive can be stopped by pressing the

•

The direction of the motor can be changed regardless of motor speed by using F/R quick start LED.

Example 2: Remote Sequence (2-Wire) & Remote Reference

- vi -

(4 – 20 mA)

This configuration is used when the start & stop signals and the frequency reference come from a remote

source, such as a PLC. It can also be used with a maintained switch when it is desirable to have the Drive

restart on restoration of power. It should not be used where safety of attending personnel might be threatened by a restart.

OPERATION:

•

Close (K1) to Run Forward.

•

Close (K2) to Run Reverse.

•

If both (K1) & (K2) are closed, the drive stops and displays the error message: “EF”.

•

Frequency reference is proportional to the signal level at Terminal FI. 4mA = 0 Hz, 12mA = 30 Hz, & 20mA = 60 Hz.

•

If the drive is put in the “Local” mode using the LO/RE quick start LED, the drive will behave the same as illustrated in Example 1.

This configuration is best when a person rather than an external controller (PLC, relay, etc.) controls the Drive.

Both potentiometers ((R1) & (R2)) should have a resistance value between 2000Ω and 3000Ω and be rated for at least 1 Watt. The trim pot is optional, but without it the manual speed pot will output 10V (60 Hz) at just three-quarters of its rotation.

OPERATION:

•

Close pushbutton (PB1) momentarily while pushbutton (PB2) is closed and the drive will start. Pushbutton (PB1) does

•

Open pushbutton (PB2) at any time and the drive will stop.

•

If switch (SW1) is open the drive will run in the forward direction. If switch (SW1) is closed, the drive will run in the reverse direction. Switch (SW1) can be operated with the drive running at any speed.

•

Frequency reference is proportional to the signal level at Terminal FV. 0V = 0 Hz, 5V = 30 Hz, & 10V = 60 Hz.

•

If the drive is put in the “Local” mode using the LO/RE quick start LED, the drive will behave the same as illustrated in Example 1.

Sequence and Reference Explained

- viii -

Sequence – refers to how the Drive is started, stopped, and told which direction to run.

When the sequence comes from the digital operator (local), the drive is started and stopped using the “RUN” and “STOP” keys on the digital operator, and direction is given via the

“FWD/REV” key. Sequence can also come from the Drive’s control terminals (remote) using either two-wire or three–wire control. The sequence inputs to the Drive do NOT

require any outside voltages to activate them. Instead, contact closures (either from switches, relay contacts or open collector circuits) activate the sequence inputs. Other

sequence sources are available, consult the Technical Manual for details.

Two-wire sequence – utilizes a “maintained” switch or relay contact. It is used on

applications where it is desirable to have the Drive restart on restoration of power. It

should not be used where safety of attending personnel might be threatened by a restart. This method is generally restricted to unattended fans & pumps, or where another controller is entrusted with the decision to restart. Direction is controlled by maintaining either a forward run or a reverse run command.

Three-wire sequence – utilizes “momentary” buttons or switches. This control scheme emulates the traditional 3-wire motor starter control. A momentary closure of a normally open run switch latches the drive in the RUN mode (STOP switch must be closed or the drive will not accept the momentary RUN command). A momentary opening of the normally closed STOP switch unlatches RUN mode bringing the drive to a stop. The three-wire sequence is used where it would be dangerous for the

Drive to restart after a power outage. This method

requires an intentional restart, as the RUN command is unlatched immediately on loss of power. Direction is determined by another maintained contact closure (closed = reverse).

Reference - The frequency reference tells the Drive how fast to run the motor. There are

several source options for the frequency reference. First, the frequency reference can come from the digital operator (local). Simply put, the motor speed can be entered into the keypad. Second, the frequency reference can come from an analog signal (remote), such

as 0 to 10 Volts DC. When 0 Volts is applied to the Drive, the Drive will run at zero speed. When 10V is applied to the Drive, it will run at full speed. Apply anything in between and the Drive will run at that corresponding frequency (2.5VDC = 25% speed = 15 Hz). Other

reference sources are available, consult the Technical Manual for details.

Local Control – is when the sequence and/or reference comes from the digital operator

Remote Control – is when the sequence and/or reference comes from the control

terminals.

PARAGRAPH

1-1

The J7 drive is a pulse width modulated general purpose AC drive which generates an adjustable voltage/frequency, three phase output for speed control of most conventional squirrel cage induction motors. Automatic stall prevention and voltage boost prevents nuisance tripping during load or line side transient conditions. The Drive will not induce any voltage line notching distortion back to the utility line and maintains a displacement power factor of not less than 0.98 throughout its speed range.

When properly installed, operated and maintained, the Drive will provide a lifetime of service. It is mandatory that the person who operates, inspects, or maintains this equipment thoroughly read and understand this manual before proceeding.

The Drive is thoroughly tested at the factory. After unpacking, verify the part numbers with the purchase order (invoice). Any damages or shortages evident when the equipment is received must be reported immediately to the commercial carrier who transported the equipment. Assistance, if required, is available from your sales representative.

If the Drive will be stored after receiving, keep it in its original packaging and store according to storage temperature specifications in Appendix 2.

Location of the Drive is important to achieve proper performance and normal operating life. The Drive should be installed in an area where it will be protected from:

• Direct sunlight, rain or moisture.

• Corrosive gases or liquids.

• Vibration, airborne dust or metallic particles.

When preparing to mount the Drive, lift it by its base, never by the front cover. For effective cooling, as well as proper maintenance, the Drive must be installed on a flat, non-flammable vertical surface (wall or panel) using four mounting screws. There MUST be a MINIMUM 3.9 in. clearance above and below the Drive to allow air flow over the heat sink fins. A minimum 1.2 in. clearance is required on each side on the Drive.

Make sure air entering the Drive is below 122°F (50°C) by adding a fan or other cooling device, if needed. See environmental specifications in Appendix 2.

The Drive leaves the factory with all parameters set for 2-Wire external reference control. Figure 1-5 must be used for all external connections.

To use the Drive in a 3-Wire application, Drive parameters n01, n02, and n03 must be reprogrammed, using the Digital Operator. Figure 1-6 must then be used for all external connections.

A. Main Circuit Input/Output

Complete wire interconnections according to Tables 1-1 and 1-2; observe the following:

• Use 600 V vinyl-sheathed wire (75°C copper) or equivalent. Wire size should be determined considering voltage drop of leads.

• NEVER connect AC main power to output terminals T1 ( U ), T2 ( V ), and T3 ( W ).

• NEVER allow wire leads to contact metal surfaces. Short-circuit may result.

• NEVER connect power factor correction capacitors or noise filters to Drive output.

• SIZE OF WIRE MUST BE SUITABLE FOR CLASS I CIRCUITS.

• Use only factory supplied installation instructions to install optional dynamic braking resistors. Failure to do so may cause equipment damage or personal injury.

• Motor lead length should NOT EXCEED 164 feet (50 meters), and motor wiring should be run in a separate conduit from the power wiring. If lead length must exceed this distance, reduce

carrier frequency and consult factory for proper installation procedures.

• Use UL listed closed loop connectors or CSA certified ring connectors sized for the selected wire gauge. Install using the correct crimp tool recommended by the connector manufacturer.

B. Control Circuit

All basic control circuit (signal) interconnections are shown in the appropriate diagram:

• Interconnections for external two-wire control in combination with the Digital Operator are shown in Figure 1-5 (for 230V or 460V rated drives).

• Interconnections for external three-wire control in combination with the Digital Operator are shown in Figure 1-6 (for 230V or 460V rated drives).

Make wiring connections according to Figures 1-1 thru 1-6 and Table 1-3, observing the following :

• Signal Leads : Terminals S1-S5 & SC; FS, FR, & FC; and AM & AC.

• Control Leads : Terminals MA, MB & MC.

•Power Leads : Input Terminals L1 (R), L2 (S), and L3 (T), and Output Terminals T1 (U), T2 (V), and T3 (W).

• Use twisted shielded or twisted-pair shielded wire (20-16 AWG (0.5-1.25mm

)) for control and signal circuit leads. Use twisted shielded or twisted-pair shielded wire (20-14 AWG (0.5-2mm

)) for shield sheath terminal (terminal ). When using shielded wire, the shield sheath MUST be connected at the Drive ONLY (terminal ). The other end should be dressed neatly and left unconnected (floating). See Figure 1-2.

• Signal leads (see above) must be separated from control leads, main circuit leads L1 (R), L2 (S), L3 (T), T1 (U), T2 (V), T3 (W), and any other power cables, to prevent erroneous operation caused by noise interference.

• Lead length should NOT EXCEED 164 feet (50 meters). Wire sizes should be determined considering the voltage drop.

It does not imply what devices are needed for a particular application, nor does it show what devices were shipped with a particular order. Therefore, disregard those items in the diagram which are not being used in your installation. However, it is recommended that an input or DC reactor be used with all ratings when wired to a source of 600 KVA or greater. Mount all power option devices as close to the Drive, and keep electrical connections as short as possible.

DO NOT run input and output wiring in the same conduit.

Figure 1-3. Customer Connection Diagram For Isolation Transformers, Input Reactors,

Input RFI Filters, DC Reactors, Output Reactors and Output RFI FIlters

NOTES

1. Connect drive ground terminal or panel to

earth ground. Always use low impedance paths and connections.

2. Mount input and output RFI filters

physically as close to the drive as possible (on the same panel, if possible). Filters should have a solid connection from filter case or ground terminal to drive panel or ground terminal (conduit with good bare metal to bare metal connections may serve as the path). If multiple input or output RFI filters are used, they must be wired in parallel.

3. Shield conductors with metallic conduit.

4. Connect output conduit in a manner that allows it to act as an unbroken shield from the drive panel to the motor casing.

5. RF noise filter (different from RFI filter) part no. 05P00325-0023 is a delta wye capacitor network which is wired in parallel with the drive input terminals. On the smaller drives with die cast chassis, it must be mounted externally. On the larger drives with sheet metal chassis, it may be mounted inside the area where the input power wiring enters the drive. On units equipped with bypass, it may be wired to the primary side of the circuit breaker and mounted to the bypass panel or sidewall.

E. Conformance to European EMC Directive

In order to conform to EMC standards, the following methods are required for line filter application, cable shielding and Drive installation.

The line filter and Drive must be mounted on the same metal plate. The filter should be mounted as close to the Drive as practical. The cable must be kept as short as possible and the metal plate should be securely grounded. The ground of the line filter and the Drive must be bonded to the metal plate with as much bare-metal contact as possible.

For main circuit input cables, a screened cable is recommended within the panel and is also suggested for external connections. The screen of the cable should be connected to a solid ground. For the motor cables, a screened cable (max. 20 m) must be used and the screen of the motor cable should be connected to ground at both ends by a short connection, again using as much bare-metal contact as practical.

For a more detailed explanation, refer to Yaskawa document TD 4077, “Installation Guidelines For EMC Directive using Yaskawa AC Drive Products.”

Ta ble 1-4 and Figure 1-4 show the line filter list for EMC standards and the installation/wiring of the Drive and line filter.
