Introduction

This Section describes the applicability of the Manual

 Product Description

The E7 Bypass unit provides a means of bypassing the Drive while allowing the motor to operate at full speed, directly from the AC line. It incorporates an AC Drive and three contactor Bypass arrangement in a single UL listed enclosure. The three electrically in terlocked IEC rated contactors isolate the Drive when operating in Bypass mode.

Control logic provides industry standard Hand/Off/Auto functions and safety circuit interlocks in both drive and Bypass op erating modes.

E7 Bypass components include: a fused 120 VAC control circuit transformer, an input Motor Circuit Protector (MCP) circuit breaker/disconnect, motor overload relay, selector switches and indicating lights.

The E7 Drive, a component of the E7 Bypass package, is a Pulse Width Modulated Drive for 3-Phase AC induction motors. This type of Drive is also known as an Adjustable Frequency Drive, Variable Frequency Drive, AC Drive, AFD, ASD, VFD, and Inverter. In this manual, the E7 Drive will be referred to as the “Drive”.

The Drive is a variable torque AC drive, designed specifically for HVAC applications in building automation, including fans, blowers and pumps. A new benchmark for size, cost, performance, benefits, and quality, the Drive includes numerous built-in features such as network communications, H/O/A, PI, parameter storage and copy functions.

The Drive has embedded communications for the popular building automation protocols, Johnson Controls Metasys® N2 and Siemens APOGEE™ FLN, as well as Modbus®. An optional LONWORKS® interface card is also available.

The LCD keypad/operator is equipped with Hand/Off/Auto functions, copy feature, 7 language choices, and 5 lines of display with 16 characters per line. User parameter settings can be recovered at any time via “User Initialization”. Optional DriveWizard software allows upload/download, as well as graphing and monitoring of drive parameters from a PC for ease of drive management.

Built-in PI control eliminates the need for closed loop output signals from a building automation system. It includes feedback display, inverse, square root and differential control functions, and maintains setpoint for closed loop control of fans and pumps for pressure, flow, or temperature regulation.

This manual is applicable to E7 Drives defined by model numbers CIMR-E7U_ _ _ _ contained within Bypass units defined by model numbers E7B_ _ _ _. This manual reflects the software version 4010.

This manual is subject to change as product improvements occur. The latest version of the manual can be obtained from the Yaskawa website

 Bypass Unit Enclosures

All Bypass units are intended for non-hazardous locations. Various enclosure types are provided to protect against the application environmental conditions:

Nema Type 1 Enclosures are constructed for indoor use to provide a degree of protection against incidental contact with enclosed electrical equipment and falling dust or dirt.

NEMA Type 12 FVFF Enclosures. NEMA provides for both non-ventilated and ventilated NEMA 12 enclosures. When ventilated, a suffix to the type number defines the ventilation method. A NEMA 12 FVFF enclosure has Forced Ventilation with inlet air Filter and outlet air Filter. The internal pressure is positive with respect to the ambient pressure. UL does not recognize NEMA 12 ventilated enclosures, therefore, these enclosures are designated NEMA 1 for UL purposes.

Physical Installation 1 - 8

Bypass Product Options

Option A - Two motor “AND” control: Allows the operation of two motors from one Drive or Bypass. Pump #1 “AND” pump #2 are operated at the same speed via the output from one Drive or Bypass. The motors are always operated simultaneously therefore, no transfer switch is involved. With the 2 motor “AND” option, motor OverLoad Relays and fuses are provided for each motor and the Drive’s internal motor overload function is disabled. The two motors can be of different capacity if this capacity difference was considered in the ordering process. The factory needs to know the FLA value of each motor controlled in order to select the correct motor overload devices and fuses. (Specifying different capacity motors results in longer, non-standard lead times).

Option D - Two motor “OR” control: A MTR #1/AUTO/MTR #2 selector switch is provided to allow local or remote motor operation selection, between two identical motors, for control by either the Drive or the Bypass (for example, Pump #1 “OR” AUTO “OR” Pump #2). In the AUTO position a contact closure from a BAS, at TB1 terminals 23 and 24, can switch between the two motors. The two motors must be the same horsepower and current draw.

Option E - RFI/EMI Filter: Filters to further attenuate possible VFD generated noise. Radio frequency interference/electro magnetic interference filters reduce conducted noise on the Drive input power leads and therefore, radiated noise from those leads. This option is installed on the input power side of the Drive, between the input contactor and the Drive.

Option F - Drive Input Fuses: Fuses capable of protecting semiconductor devices, rated at 200 kAIC are connected to the line side of the Drive, between the input contactor and the Drive, to protect the Drive semiconductors when motor or output conductor short circuit faults occur.

Option J - Enable Embedded Serial Communications: A no cost option. The Drive in a Bypass unit is capable of network communication via one of 3 embedded protocols. Specifying option J and the protocol to be employed (Metasys, APOGEE or Modbus) will provide the necessary parameter settings and wiring (jumpers) to be network ready when delivered (Project specific H5-0X parameters are setup by the user).

Option K - 5% Output Reactor: Employed on the output side of the Drive for reduction of peak voltages applied to the driven motor. In long Drive to motor lead length situations, high carrier frequency and reflected waves can cause high voltage spikes at the motor. An output reactor provides motor protection in these long motor lead length situations. This option is installed on the output power side of the Drive, between the output contactor and the Drive.

Option L - Serial Communication, Echelon LonWorks: An isolated RS-422/485 circuit board provides LonTalk protocol for network communication to a BAS. This option plugs into the CN2 connection on the Drive control circuit board.

Option M - 4 to 20 mA Output: Provides two programmable 0 to 10 VDC analog outputs or two programmable 4 to 20 mA analog outputs.

Option N

of voltage distortion and electrical noise. This passive wye-delta capacitve filter is intended for installation on the VFD input in order to protect other sensitive electronic loads, it provides attenuation of conducted RFI and EMI.

Option P - Pressure to Electrical Transducer: This transducer is employed when converting a pneumatic signal to an electrical signal for use as the Drive speed command input. The need for this option comes up on retrofit applications when the pneumatic signal that formerly controlled the pneumatic actuator on Inlet Guide Vanes (IGV), for example, is now to be used to control the fan speed via the Drive. This option is wired to Drive terminals +V, A2 and AC, parameters H3-10 and H3-11 are used for final field calibration of this input if there is jobsite variation from the typical 3 to 15 PSIG pneumatic signal input range.

- Input Capacitive Network Radio Frequency Interference Filter: Electronic equipment can be sensitive to low levels

Physical Installation 1 - 9

Option R - 3% Input Line Reactor: Employed on the input side of the Drive for Total Harmonic Distortion (THD) suppression. A line reactor also minimizes the potential for Drive input diode damage from line transients and reduces voltage peaks on the DC bus capacitors. This option is installed on the input power side of the Drive, between the input contactor and the Drive.

Option S - Speed Potentiometer: A door mounted single turn potentiometer for manual control of Drive output and motor speed. This option is wired to Drive terminals +V, A1 and AC and is used as the local speed command input to the Drive instead of the keypad up and down arrows. Parameters for use of this option in conjunction with other input signals are detailed in Table 5.2.

Option W - Engraved Plastic Nameplate: An enclosure identification nameplate to carry the controlled equipment “tag number”.

Option X - 3% DC Bus Reactor: Attenuates harmonic distortion by limiting the rate of rise of the input current. The bus reactor is wired to the Drive (+1) and (+2) DC bus terminals to provide the equivalent impedance of a 3% input reactor. This option is only used on the low end of the horsepower range where DC bus reactors are not a standard Drive component (25 HP and below @ 208 VAC, 25 HP and below @ 240 VAC, and 30 HP and below @ 480 VAC.)

Option Z - 5% DC Bus Reactor: Attenuates harmonic distortion by limiting the rate of rise of the input current. The bus reactor is wired to the Drive (+) and (-) DC bus terminals to provide the equivalent impedance of a 5% input reactor. This option is only used on the low end of the horsepower range where DC bus reactors are not a standard Drive component (25 HP and below @ 208 VAC, 25 HP and below @ 240 VAC, and 30 HP and below @ 480 VAC.)

In a Bypass unit the keypad operator is mounted flush with the hinged door of the enclosure. The addition of a HAND/ OFF/AUTO selector switch for the Bypass logic circuit makes the Hand, Off and Auto keys on the standard Drive keypad

operator redundant. In this Bypass configuration the keypad Hand, Off and Auto keys are disabled in the Drive firmware and a mask (membrane) is placed over the keypad operator to cover these keys, avoiding the potential for confusion. The membrane over the Drive keypad is order a separate keypad, part number CDR001115).

On the enclosure door just below the digital operator are six 22 mm, 24 VAC LED indicating lights for: “Control Power”, “Drive Run”, “Bypass Run”, “Motor OL/Safeties Fault “Drive Fault” and “Smoke Purge”. LED type indicating lights are pro vided to improve the reliability well beyond that of incandescent bulbs. LED’s have a MTBF of 100K hours, eliminating any need for “push to test” type pilot lights.

CAUTION

Only qualified service personnel should use the defeater feature.

A three position rotary switch employed to control the source of the motor start and speed commands in either the Drive or Bypass operating modes.

Off Position: No power is applied to the Bypass circuit. The Drive input and output contactors are energized and the Drive is stopped (run command removed). The Off position takes precedence over a serial communication run command.

Auto Position – Drive Mode: The Drive input and output contactors are energized. The Drive is enabled to receive a run command contact closure and speed input analog signal from a Building Automation System (BAS).

Auto Position – Bypass Mode: The motor full speed across-the-line run/stop is controlled by a BAS contact closure, energizing the Bypass contactor.

The H/O/A switch must be in the AUTO position if serial communication is to be used for Drive run, stop and speed control.

The Bypass contactor is energized causing the motor to run at full speed directly across-the-

 DRIVE/BYPASS Selector Switch

A two position rotary switch selecting motor operation from the Drive or directly across-the-line. When transferring from Drive operation to Bypass operation, the logic circuit will require the Bypass unit to stop the motor before completing the transfer to full speed across-the-line operation.

 NORMAL/TEST Selector Switch

A two position rotary switch, test position is used to energize the Drive input contactor while operating in the Bypass mode (via the HAND or AUTO switch position). In Drive mode switching from NORMAL to TEST position will remove the power from the Drive and the motor will stop. In Bypass mode the test position powers the Drive for programming or other “tests” while keeping it isolated from the motor.

 MCP Motor Circuit Protector Circuit Breaker/Disconnect

Electrically located on the input power side of the Bypass unit, the MCP adjustable, instantaneous trip circuit breaker provides protection from short circuits for the motor power cables. The Bypass three phase input power connection is made to the input terminals of the MCP. The door mounted rotary operating mechanism is a convenient means of disconnecting the Bypass unit from line power for equipment maintenance. The MCP must be in the OFF position in order to open the enclosure door. Service and troubleshooting personnel are provided with a means to defeat this door interlock. The rotary handle provides trip indication and can be padlocked in the OFF position.

Slide Switches for switch selectable functions (Auto Transfer, Remote Transfer and Smoke Purge) are behind this ribbon cable connector. See Fig. 1.9 for details.

 Contactors

The Bypass is a “3 contactor Bypass” circuit employing IEC rated contactors in an electrically interlocked arrangement to allow mutually exclusive operation in Drive or Bypass modes. To minimize enclosure space requirements, they are mounted in a 3 contactor assembly. The control logic and “soft start” characteristic of the Drive limit the Drive input and output contactors to motor FLA current or less. For this reason, the Drive input and output contactors have lower current ratings than the Bypass contactor. The Bypass contactor is exposed to motor inrush current (LRA) when starting the motor across-the-line and therefore requires a higher current rating.

 OverLoad Relay

The OverLoad Relay (OLR) is mounted to the contactor assembly or back panel (depending on rating), just above the Bypass contactor (see Figure 1.7). Electrically on the output power side of the Bypass unit, the adjustable thermal OLR provides overload protection for the motor in both the Drive and Bypass operating modes. The Bypass three phase output power connection to the motor is made to the output terminals of the overload relay. The OLR is set up in the factory to be a manual reset device, requiring operator attention if an overload trip-out is experienced.

 Control Power Transformer

A Control Power Transformer (CPT) is provided to power the Bypass 120 VAC control circuit. The VA capacity is determined by the control circuit and optional functions specified for the unit. 100 VA of extra transformer capacity for customer control logic is provided in the standard unit and additional capacity is available as an “engineered” or “custom” option. The CPT primary is fused in both legs, the secondary is fused when required by NEC (above 350 VA). One side of the transformer secondary is grounded to the Bypass enclosure.

 Relay and Selector Switch Logic

Operating elements such as indicating lights and selector switches, as well as the control relay logic, have been incorporated into a PCB assembly to eliminate the potential for loose wires after shipment and to control factory costs. The operating elements are located on PCB A3, mounted to the inside of the enclosure door and ribbon cable connected to the control relay logic PCB A2. The control relay logic PCB A2 is mounted to the left hand side of the enclosure and contains the control circuit field wiring terminal strip (TB1).

 Drive/Bypass logic interlocks explained

The Bypass 120 VAC relay logic circuit is interconnected with the Drive multi-function digital input terminals and multifunction digital output terminals to allow a single customer interface to control both Drive and Bypass circuits. Some of these terminals are therefore not available for other field use.

Terminals M1 and M2 are a normally open Drive run relay contact used to communicate the Drive operational mode to the 120 VAC relay logic circuit.

Terminals M3 and M4 are a normally open serial com. run status relay contact used to communicate the Drive operational state to the 120 VAC relay logic circuit.

Terminals MA and MC are a normally open Drive fault relay contact used to communicate the Drive fault status to the 120 VAC relay logic circuit.

 PCB Jumpers explained

The S101 “Berg pin” jumper on the control relay logic PCB A2 is not for field use. It is employed only in the factory to enable the 2 motor “OR” configured option. It is removed when this option is present and must be in place when this option is not part of the unit specification (See Figure 1.9). The S102 “Berg pin” jumper on the control relay logic PCB A2 is not for field use. It is employed only in the factory to enable the Run/Stop Push Button (3 wire control) configured option. It is removed when this option is present and must be in place when this option is not part of the unit specification (See Figure 1.9). TB1 terminals 1 and 2 are jumpered (J1) as the unit is shipped from the factory. If a customer supplied series circuit of NC safety devices is to be used, this jumper is removed and the safety circuit connected between terminals 1 and 2. TB1 terminals 5 and 6 are jumpered (J2) as the unit is shipped from the factory. If a customer supplied Drive NO enabling contacts are to be used (such as a damper end switch or occupied cycle timer), this jumper is removed and the enabling contacts wired between terminals 5 and 6.

 Switch Selectable Functions:

Slide Switches

PCB Jumpers

The slide switches used to select these functions are located on the relay controller Printed Circuit Board (PCB) A2 (See Figure 1.9). The factory default is for these functions to be de-selected.

Smoke Purge: When enabled (switch S105) this function allows a contact closure, between terminals 17 and 18 of TB1, to transfer motor operation to bypass for a maximum capacity smoke control function. When in smoke purge mode, during emergency fire/smoke situations, the motor overloads and safety interlock circuit are overridden to shift the priority to protecting people rather than equipment.

Auto Transfer to Bypass: If enabled (switch S103), the E7 Bypass unit will automatically transfer the motor operation from Drive to Bypass in the event of a Drive fault. When the Drive fault condition has cleared, this function is reset by moving the circuit breaker to the OFF position, waiting for the keypad to go blank, then switching back to the DRIVE position.

Before selecting this function in fan applications, care must be taken to ensure that the duct-work is

IMPORTANT

Remote Transfer to Bypass: When selected (switch S104) this function allows a contact closure from a BAS, between terminals 25 and 26 of TB1, to transfer motor operation from Drive mode to Bypass mode. This remote tranfer to Bypass function overrides the DRIVE/BYPASS manual switch.

designed to handle the pressure resulting from full speed operation with the VAV terminal unit dampers at minimum position or closed.

Physical Installation 1 - 23

Checking and Controlling Installation Site

Install the Bypass unit as described below and maintain the specified operating conditions.

 Installation Site

Location of the Bypass unit is important to achieving proper performance and design operating life. Install the Bypass unit as close as possible to the motor. The NEMA type 1 & 12 enclosed units should be installed in an area where it will be protected from: Direct sunlight, rain or moisture, corrosive gasses or liquids, vibration and dust or metallic particles. The ambient air available for cooling the unit should be 104° F (40° C) or less.

Wall mount units require a minimum 6 inch clearance above and below, to achieve adequate heat sink cooling. When the addon box is employed for optional equipment, no additional bottom clearance is required.

No side clearance is required for cooling because the cooling air flow is in and out of the enclosure door at the front surface of the unit (do not block the air flow louvers). Clearance for the opening swing of the enclosure door should be considered when placing these units. The door is hinged on the left and must open through at least a 90 degree swing with a 120 to 180 degree swing being preferable (minimum clearance is 1.5”).

Floor mounted units require a minimum clearance of 10 inches above the enclosure to allow for air flow over the heat sink fins.

Install the Bypass unit under the following conditions in UL pollution degree 1 & 2 environments. This excludes wet locations where surfaces may become conductive due to moisture and contaminant loading.

Table 1.7 Installation Site

Type Ambient Operating Temperature Humidity Plenum Rated

NEMA Type 1 & 12 14 to 104°F (-10-to-+ 40°C) 95%-RH-or-less-(no-condensation) Ye s

Observe the following precautions when mounting the Bypass unit.

• Install the Bypass unit in a clean location that is free from oil mist and dust.

• Install the Bypass unit in an environment where metal shavings, oil, water, or other foreign matter will not get into the

Bypass enclosure.

• Install the Bypass unit in a location free from radioactive materials.

• Install the Bypass unit in a location free from harmful gasses and liquids.

• Install the Bypass unit in a location without excessive vibration.

• Install the Bypass unit in a location free from chlorides.

• Install the Bypass unit in a location not in direct sunlight.

• Install the Bypass unit on a non-combustible surface.

Physical Installation 1 - 24

 Controlling the Ambient Temperature

To enhance the reliability of operation, the Bypass unit should be installed in an environment free from extreme temperature variations. Do not store this Technical Manual or any other documents on the top surface of the Bypass unit, they may cover the heat sink cooling air discharge opening and cause the unit to overheat.

If the Bypass unit is installed in an enclosure (such as an electrical control box in an air handling unit), use a cooling fan or air conditioner to maintain the Bypass unit internal air temperature below 113°F (45°C).

 Protecting the Bypass Unit from Foreign Matter

During Bypass unit installation and project construction, it is possible to have foreign matter, such as metal shavings or wire clippings, fall inside the Bypass unit. To prevent foreign matter from falling into the Bypass unit, place a temporary cover over the unit.

Always remove the temporary cover from the Bypass unit before start-up. Otherwise, ventilation will be reduced, causing the Bypass unit to overheat.

Physical Installation 1 - 25

 Installation Orientation and Enclosure Considerations

Install the Bypass unit vertically so as not to reduce the cooling efficiency. When installing the Bypass unit, always provide the recommended installation clearances to allow normal heat dissipation.

When preparing to mount the unit, lift it by the base (or lifting rings when provided), never by the enclosure door. For effective cooling and proper maintenance, the wall mounted units must be installed on a flat non-flammable vertical surface using four mounting screws.

To mount units employing the add-on box, a hex head mounting screw and socket wrench will be required for the lower left mounting hole location. See Figure 1.15.

For all units, the MCP handle should be in the OFF position to open the enclosure door. The wall mount units have two full turn fasteners, CCW to open, that require a flat blade screwdriver to open the enclosure door.

IMPORTANT

WARNING

Determine the wire size for the main circuit so that line voltage drop is within 2% of the rated voltage. Line voltage drop is calculated as follows:

Line voltage drop(V) = √3 x wire resistance (Ω/km) x wire length (m) x current (A) x 10

Prior to removing any protective cover or wiring any part of the Drive, remove all power sources, including main input power and control circuit power. Wait a minimum of 5 minutes after power removal, before removing any cover. The charge lamp located within the Drive should be off prior to working inside. Even if the charge lamp is off, one must measure the AC input, output, and DC Bus potential to insure safe levels prior to resuming work. Failure to adhere to this warning may result in personal injury or death.

Electrical Installation 2 - 3

 Cable Length between Drive and Motor

The Bypass unit should be installed as close as possible to the motor to minimize the length of load side power cable needed between the Drive and the motor. If the cable between the Drive and the motor is long, the high-frequency leakage current will increase, causing the Drive output current to increase as well. This may affect peripheral devices. To prevent this, reduce cable length, or if necessary, adjust the carrier frequency (set in C6-02) as shown in Table 2.1.

The line side power cables, load side power cables and the control wiring should all be run in a separate conduit. Careful attention to this recommended design practice will avoid many potential motor and Drive related problems.

Table 2.1 Motor Cable Length vs. Carrier Frequency (C6-02)

Motor Cable Length 164 ft. (50m) maximum 328 ft. (100m) maximum More than 328 ft.(100m)

Carrier Frequency 15kHz maximum 10kHz maximum 5kHz maximum

(See the limitations on carrier frequency, based on Drive capacity and model number in Appendix B).

 Grounding

NO

OK

NO

 Drive and Motor Ground Wire Landing

The Drive ground lug (terminal ) is connected to the enclosure. The enclosure ground lug must be connected to earth

ground. See Figures 2.1 and 2.2.

The Drive has a second ground lug to accept the motor ground lead. See Figure 2.9.

 Ground Wiring Precautions

Observe the following precautions when connecting the ground wire:

1. 208-240 VAC Drives should have a ground connection with resistance of less than 100 Ω..

2. 480 VAC Drives should have a ground connection with resistance of less than 10 Ω..

3. Do not share the ground wire with other devices, such as large-current electrical equipment.

4. Always use a ground wire that complies with technical standards on electrical equipment and minimize the length of the ground wire. Leakage current flows through the Drive. Therefore, if the distance between the ground rod and the ground terminal is too long, potential on the ground terminal of the Drive will become unstable.

5. When using more than one Drive, be careful not to loop the ground wire.

Fig 2.4 Ground Wiring Examples

For grounding connection to earth ground see Figures 2.1 and 2.2.

 Control Circuit Ground Terminals

The removable Drive control terminal card provides two ground terminals (marked TB3 and TB4) to accept the control wire shield connection. The control wire shield should be connected on this end only, the opposite end should be isolated with electrical tape.

IMPORTANT

Grounding of the Bypass enclosure and motor is required for proper system operation.

Control Wiring

 Bypass Field Control Wire Landing

The Bypass field control wiring is terminated on the relay control PCB A2, Terminal block TB1. The terminal designations are labeled on the door, adjacent to PCB A2 (see Figure 2.6). Route the control wiring as shown in Figure 2.5.

TB1 terminals 1 and 2 are jumpered (J1) as the unit is shipped from the factory. If a customer supplied series circuit of NC safety devices is to be used, this jumper is removed and the safety circuit connected between terminals 1 and 2. TB1 terminals 5 and 6 are jumpered (J2) as the unit is shipped from the factory. If customer supplied Drive NO enabling contacts (open = Drive disabled, closed = Drive enabled) are to be used (such as a damper end switch or occupied cycle timer), this jumper is removed and the enabling contacts wired between terminals 5 and 6.

Electrical Installation 2 - 9

 Damper Control Circuit

TB1 terminals 19 and 20 are provided to power a customer supplied 120 VAC relay, electric actuator or electro-pneumatic solenoid air valve employed to control a pneumatic damper actuator, typically for outdoor air intake damper interlock. The power rating of the connected device should be no more than 40 VA continuous and 70 VA inrush. An off command (from the H/O/A switch) or a safety device trip-out will immediately de-energize these terminals. At the same time the Drive will begin the ramp to stop process (in Drive mode with the default stopping method). In some air handling unit applications operation during the ramp to stop time with the dampers closed may be problematic. Over pressurization of ducts or trip-out on high DC bus voltage, due to overhauling of the load by other fans in the system, are possible outcomes. One solution is to reprogram the stopping method in parameter b1-03 to “coast to stop” eliminating the potential for both of these problems.

 Building Automation system Run/Stop circuit:

A control terminal block position (TB1, terminals 3 and 4) is provided to connect the Normally Open (NO) Run/Stop contact from a BAS or other remote controller for auto mode control.

There must be continuity between these terminals in order for the motor to run, in auto mode.

 Safety Interlock Circuit:

A control terminal block position (TB1, terminals 1 and 2) is provided to connect the series circuit of Normally Closed (NC) safety devices such as: freeze up thermostats, smoke/fire sensors, high pressure limits, temperature limits or vibration detectors.

There must be continuity between these terminals in order for the motor to run.

 Building Automation System Interlock Circuit (Drive and Bypass enable input):

A control terminal block position (TB1, terminals 5 and 6) is provided to connect Normally Open (NO) enabling contacts such as: damper end switches or occupied cycle timers.

There must be continuity between these terminals in order for the motor to run.

 Switch Selectable Functions:

The slide switches used to select these functions are located on the relay controller Printed Circuit Board (PCB) A2 (See Figure 1.9). The factory default is for these functions to be de-selected.

Smoke Purge: When enabled (switch S105) this function allows a contact closure, between terminals 17 and 18 of TB1, to transfer motor operation to bypass for a maximum capacity smoke control function. When in smoke purge mode, during emergency fire/smoke situations, the motor overloads and safety interlock circuit are overridden to shift the priority to protecting people rather than equipment.

Remote Transfer to Bypass: When selected (switch S104) this function allows a contact closure from a BAS, between terminals 25 and 26 of TB1, to transfer motor operation from Drive mode to bypass mode. This remote tranfer to bypass function overrides the Drive/Bypass manual switch.

P = Wire Pair

The auto mode speed reference (speed command) field wiring connection is made directly to Drive terminals A2 (signal positive), AC (signal common) and G (shield). Keep this lead length as short as possible to maintain signal quality. Insulated twisted shielded pair wire (2 conductor # 18 ga, Belden 8760 or equivalent) is required. Do not run these wires in the same conduits as other AC power or control wires. The shield must be connected on this end only, stub and isolate the other end. The signal employed is 4 to 20 mA with parameter H3-08 set for “2: 4 - 20 mA”. For 0 to 10 VDC, parameter H3-08 is set for “0: 0 - 10 VDC” and the E7 control board DIP switch S1-2 must be in the OFF position. (See Figure 2.11)

For remote operation, keep the length of the control wiring to 50 m or less. Separate the control wiring from high-power lines

(input power, motor leads or relay sequence circuits) to reduce induction from peripheral devices.

When setting speed commands from an external speed potentiometer (and not from a Digital Operator), use shielded twisted-

pair wires and ground the shield to terminal E(G), as shown in Figure 2.8. Terminal numbers and wire sizes are shown in

Table 2.5.

 Wiring Checks

After all wiring is completed, perform the following checks:

1. Is all wiring correct?

2. Have all wire clippings, screws or other foreign material been removed from the Drive and Bypass enclosure?

3. Are all terminal screws tight?

 Control Circuit Wiring Precautions

Observe the following precautions when wiring control circuits:

1. Separate control wiring from power/motor wiring and other high-power lines.

2. Separate wiring for control circuit terminals for digital outputs from wiring to other control circuit terminals.

3. If using an optional external power supply, it should be a UL Listed Class 2 power supply source.

4. Use twisted-pair or shielded twisted-pair cables for control circuits to prevent operating faults. Prepare cable ends as

shown in Figure 2.10.

5. Connect the shield wire to terminal E(G).

6. Insulate the shield with tape to prevent contact with other signal lines and equipment.

AUTO REF Lit when set up for remote speed command, see Table 3.3.

ALARM Lit when a fault has occurred and flashing when an alarm has occurred.

 Drive AUTO Sequence (SEQ) and AUTO Reference (REF) indicators

The Bypass operates differently than a stand alone Drive with regard to these two indicators. The Bypass control logic interfaces with the Drive via terminals that would be used, in a Drive only installation, for the AUTO Sequence (Run Command), and AUTO Reference (Speed Command).

Since these terminals are active and the appropriate parameters configured for the Bypass unit operation (see Tables 5.1 and

5.2), the AUTO Sequence and AUTO Reference LED’s will be lit even when the H/O/A is in HAND position (local control), providing both the run and speed command from the local control panel. The control signals are “Local” to the Drive and Bypass unit, but “Remote” (AUTO) from the Drive itself.

An exception to this rule occurs for the AUTO REF indicator when serial communication is employed.

Start Up and Operation 4 - 1

Start Up Introduction

In order to provide you with the most reliable Drive and Bypass unit available, and to avoid any extra costs related to loss or reduction of warranty coverage, an authorized Yaskawa service representative should complete this start up procedure. Please complete the checklist in this document and maintain it in a secured location. Should you have a need to contact Yaskawa in the future, technical service personnel may request information from this document.

CAUTION

Procedures within this document assume that start up is being accomplished by a Yaskawa authorized service person who has training on the product and is capable of working through the detailed steps with power applied to the Bypass unit while the enclosure door is open.

Start Up and Operation 4 - 2

BYPASS START UP PREPARATION

 1. Review this Bypass Technical Manual and any option instructions and schematics shipped with the Drive and Bypass

unit.

 2. Verify that the model numbers and voltage ratings are as specified in the purchase order by matching the nameplate

data for each unit to the purchase order.

 3. Verify that the unit has been installed in accordance with Chapter 1, Receiving and Mechanical Installation and

Chapter 2, Electrical Installation.

 4. Inspect the security of the supply line power, ground connections and all control circuit connections as identified in

Chapter 2, Electrical Installation.

Double check all the power wires and motor wires.

Verify that the electrical supply power lines are connected to the input circuit breaker and that the motor leads are connected to the output terminals of the overload relay. Ensure that all connections are tight, loose wire connections may cause intermittent problems or overheating. Factory connections sometimes come loose during shipment.

 5. Review the installer’s “as wired” schematic. Determine if a driven motor “safety circuit” is connected. This is a series

circuit of NC contacts from devices such as a smoke/fire sensor, freeze-up thermostat or high static pressure limit switch. Verify that these customer emergency contacts are properly terminated in the Bypass safety shutdown circuit. These contacts should be wired between terminal TB1-1 and TB1-2. No field programming is required.

Verify that all other field installed wires are correctly terminated (included the shields).

 6. Verify that the motor is wired for the application voltage. Record the motor nameplate information:

 7. Verify that the input voltage matches the Bypass unit rating.

 8. Verify that the motor rated full load amps (FLA) does not exceed the rated output current of the Drive and Bypass

controlling it. When multiple motors are simulaneously operated by the Drive, the sum of all motor FLA values must be less than or equal to that of the Drive and Bypass controlling them.

(Please review “Bypass Start Up Preparation” on page 4-3)

 1. Before applying power, make sure that the following conditions are met:

• The DRIVE/BYPASS switch is in the DRIVE position.

• The HAND/OFF/AUTO switch is in the OFF position.

• The NORMAL/TEST switch is in the NORMAL position. [Note: If the TEST position is selected while the DRIVE/BYPASS switch is in the DRIVE position, the fault code “UV, DC Bus Undervolt” will be briefly displayed and the Drive will shut down. TEST mode is only available when in the BYPASS position.]

• The VAV terminal unit dampers, in supply fan applications, are open to prevent duct flexing or damage in a full speed, across the line starting situation.

• The electro-mechanical motor OverLoad Relay (OLR) (S10) is adjusted to equal the Full Load Amps (FLA) value from the motor nameplate.

The OLR is mounted to the contactor assembly or back panel (depending on rating), just above the Bypass contactor. See Figure 4.1. Electrically on the output power side of the Bypass unit, the adjustable thermal OLR provides overload protection for the motor in both the Drive and Bypass operating modes. The OLR is set up in the factory to be a manual reset device, requiring operator attention if an overload trip-out is experienced.

 2. Apply power to the Drive and Bypass package. Ensure that all three phases are present and that the input voltage is

correct for the system being set up. The CONTROL POWER ON, STOP and AUTO SEQ and REF LEDs on the control panel should be ON and the display will be in the “-DRIVE-/Operation” menu showing the active speed command. [Note: If the MOTOR OL/SAFETIES FAULT light is ON, press the reset button on the motor OLR (S10) and check the “safety device” circuit between terminals TB1-1 and TB1-2.].

To maintain overcurrent, short-circuit, and ground-fault protection, the manufacturer’s instructions for setting the motor OLR must be followed.

Start Up and Operation 4 - 4

 3. Various menus are directly available by pressing the MENU key (see Chapter 3). When in the “-DRIVE-/Operation”

menu, the Drive can accept a run command from local (Hand mode) or remote (Auto mode) sources. Press the MENU key until the “-ADV-/Programming” menu is displayed. From here, any of the parameters can be accessed and changed using the ,, and DATA/ENTER keys. See Appendix A for a list of programmable features. The “-VERIFY-/Modified Consts” menu can be used to review or modify only those parameters that have been changed from the Drive’s default values. Using the ,, and DATA/ENTER keys as needed, verify that the parameters are correct for the Drive and installation conditions. See the Factory Parameter Settings printed in Table 1 and Table 2 on page 2 of the Schematic Diagram that was shipped with the unit. Consider any additional parameter settings that may be needed by this specific application.

The Factory Parameter Settings table documents Drive parameter settings, required to interface with the Bypass logic circuit, that have been established at the factory and stored in a dedicated location in memory as “User Initialization” values (think of it as a “back-up file”). If additional parameters are set to the specific needs of the application project, and the system operation has been checked and verified, then the “User Initialization” values should be stored in memory again by selecting and entering “1: Set Default” in parameter o2-03.

When there is a need for re-initialization of the “user” parameters (re-setting to the “User Initialization” values) of the Bypass unit, then a “User Initialization” function should be carried out by selecting “1110: User Initialize” in parameter A1-03. This will re-establish the drive set-up required for the Bypass application and any “user” parameter values that have been stored.

The factory parameter settings required to interface with the bypass logic circuit have also been stored in the digital keypad memory. If there is a need for re-initialization (re-setting to a known factory starting point for trouble-shooting purposes) of the Bypass unit, then the “back-up file” in the digital keypad memory can be copied to the drive. In parameter o3-01 select “2: OP->INV WRITE” to carry out the copy function.

Table 1 of the schematic is also used to document parameters that have been factory set to typical values for fan and pump applications. These parameters may be changed to meet the needs of the specific application. In Table 5.1 of this manual shading is used to distinguish between settings required by the Bypass logic and those that may be changed.

 4. From the “-ADV-/Programming” menu, go to parameter E1-01 and select the nominal input voltage that the Drive will

receive in this specific application. The overall voltage classification of the Drive cannot be changed by this parameter. However, the input voltage should be adjusted within the range available for the given voltage “class” of the Drive to match the input voltage level normally found on the jobsite. For example, 480 VAC class Drives may be employed on nominal three phase voltage distribution systems of: 380, 400, 415, 440, 460 or 480 VAC. The factory default values may need to be changed to meet the needs of the application distribution voltage.

 5. From the “-ADV-/Programming” menu, go to parameter E2-01 and enter the Motor rated current. Set this parameter to

the Full Load Amps (FLA) rating shown on the motor nameplate. This is essential for proper Drive operation and motor overload protection.

 6. If the unit being started has the Speed Potentiometer option, proceed directly to step 7. Otherwise, press the

MONITOR key to return to the “-DRIVE-/Operation” menu. The AUTO SEQ and REF LEDs and the STOP and CONTROL POWER ON LEDs on the control panel should be ON at this time.

To start the motor in Drive mode, move the HAND/OFF/AUTO switch to HAND. The DRIVE RUN LED will turn

ON and the Drive will ramp up to “6 HZ”. Verify that motor rotation is correct. [Note: In Bypass packages, the Drive is programmed at the factory for 5 seconds of DC injection braking at start (to stop a rotating motor when switching from BYPASS to DRIVE), expect to see this delay each time the Drive is started.]

If the direction of motor rotation is wrong, turn the HAND/OFF/AUTO switch to OFF; and turn the Power OFF! Wait for the Red CHARGE LED (near the Drive power terminals) to go out. When it does, swap the wires in the motor junction box for T1 & T2 or on the output terminals of the motor OLR (S10). Tighten the terminal lugs, reapply the power, turn to HAND and re-check the rotation direction.

Start Up and Operation 4 - 5

 7. If a Speed Potentiometer option is present, turn the Speed Potentiometer fully counterclockwise to ensure that the

local speed command is zero. If necessary, press the MONITOR key to return to the “-DRIVE-/Operation” menu. The AUTO SEQ and REF LEDs and the STOP and CONTROL POWER ON LEDs on the control panel should be ON at this time.

To start the motor in Drive mode, move the HAND/OFF/AUTO switch to HAND, then rotate the Speed Potentiometer clockwise to establish a speed command in the 6 to 10 Hz range. The DRIVE RUN LED will turn ON and the Drive will ramp up to this setting. Verify that motor rotation is correct. [Note: In Bypass packages the Drive is programmed at the factory for 5 seconds of DC injection braking at start (to stop a rotating motor when switching from BYPASS to DRIVE), expect to see this delay each time the Drive is started.]

If the direction of motor rotation is wrong, turn the HAND/OFF/AUTO switch to OFF; and turn the Power OFF! Wait for the Red CHARGE LED (near the Drive power terminals) to go out. When it does, swap the wires in the motor junction box for T1 & T2 or on the output terminals of the motor OLR (S10). Tighten the terminal lugs, reapply the power, turn to HAND; and re-check the rotation direction.

 8. With correct motor rotation, press the MONITOR key, if necessary, to return to the “-DRIVE-/Operation” menu.

Using the observing operation. If excessive vibration of the driven load is noted at specific input frequencies, the Jump Frequency function may be used to eliminate this vibration, by programming d3-01 through d3-04.

 9. Determine whether the remote speed command is a 0-10 VDC or a 4-20 mA signal. The positive side of the signal

should be connected to terminal A2 of the Drive terminal strip. The COMMON of the remote speed command signal should be connected to terminal AC of the Drive. See the connection diagram on page 1 of the Bypass schematic. [Note: The factory default is 4-20 mA, to change to 0 to 10 VDC adjust parameter H3-08 to “0: 0-10VDC” and move Drive DIP switch S1-2, on the Drive terminal PCB to the OFF position.]

,, and DATA/ENTER keys, manually run the Drive throughout its entire operating range, while

 10. Observe if the remote speed command can achieve the minimum and maximum speeds desired. If not, perform the

following (see Chapter 5):

For 0-10 VDC input at Terminal A2

1. With no input, adjust the Bias (H3-11 setting) until an output of “0.0 Hz” is obtained.

2. With full scale input, adjust the Gain (H3-10 setting) until an output of “60.0 Hz” (or other desired maximum

frequency) is obtained.

For 4-20 mA input at Terminal A2

1. With 4 mA input, adjust Bias (H3-11 setting) until an output of “0.0 Hz” is obtained.

2. With 20 mA input, adjust Gain (H3-10 setting) until an output of “60.0 Hz” (or other desired maximum

frequency) is obtained.

 11. Turn the HAND/OFF/AUTO switch to AUTO, then request a run command and speed reference signal from the

building automation system to confirm remote (auto) operation.

 12. In preparation for testing the Bypass, observe the trip setting of the circuit breaker (CB1). The trip point is factory set

at the lowest possible setting and must be adjusted for each application. This breaker will trip due to inrush current and load inertia unless it is reset!

• For fan applications adjust the trip setting to ten times motor FLA.

• For pump applications adjust the trip setting to six times motor FLA.

If circuit breaker tripping is experienced at these settings during motor starting on Bypass, increase the setting gradually until the motor can be started without circuit breaker tripping.

Fig 4.2 Typical MCP Circuit Breaker

IMPORTANT

To maintain overcurrent, short-circuit, and ground-fault protection, the manufacturer’s instructions for setting the instantaneous-trip circuit breaker must be followed.

 13. Turn the HAND/OFF/AUTO switch to OFF and the DRIVE/BYPASS switch to BYPASS. The Drive will ramp the

motor to zero speed, then the Drive will be de-energized and control transferred to Bypass mode. Be prepared to monitor the rotation direction of the motor in Bypass operation. “Bump” the HAND/OFF/AUTO switch to the HAND position and quickly back to OFF. Check the motor rotation.

Do not allow the motor to continue operating in

BYPASS until rotation is correct!

If the rotation direction in Bypass is correct, skip the rest of this step. If not, carry out the following corrections:

1. Turn OFF the incoming power feed to the Drive. Since the correct rotation in Drive mode was previously established, do not change any output wires at the motor.

2. Instead, verify that power to the circuit breaker is OFF. Then swap L1 & L2 on the input side of the circuit breaker/disconnect switch (CB1). This will affect rotation in Bypass operation only. Once connections are complete and tight, reapply the incoming power and repeat the previous step to re-check the rotation direction in Bypass mode.

 14. Run the motor in Bypass by placing the HAND/OFF/AUTO switch in HAND. Record all the phase voltages and

currents at this time.

 15. Select the OFF position of the HAND/OFF/AUTO switch and place the BYPASS/DRIVE switch in DRIVE. Turn to

the HAND position and scroll the Speed Command to “60 HZ” operation. Monitor the voltages and currents in each of the output phases at full speed to make sure the voltages are balanced and the currents are within the motor nameplate rating during accel, stable speed, and decel.

 16. If this application requires the Drive to operate in PI mode, see Chapter 5.

 17. For fan applications, with the HAND/OFF/AUTO switch set to AUTO, have the building automation system give the

Drive a run command and a speed command. Put the BYPASS/DRIVE switch into BYPASS and let the load speed up and stabilize. Then move the switch to DRIVE. Observe if the DC braking is enough to stop the fan in the time period set in parameter b2-03 (5 sec factory setting). If not, set this parameter to its maximum setting, which is 10.0 seconds. If this is not enough, slowly increase the braking current setting (parameter b2-02) but do not go above 90% to protect the Drive output devices.

For serial communication, refer to TM.E7.21 (APOGEE FLN) and TM.E7.22 (Metasys N2).

Bypass Operation Description

(For manual switch positions, control inputs and switch selectable functions.)

The Bypass has two modes of operation: Bypass and Drive. When in the Bypass mode the connected motor is run directly from the incoming AC line, whereas in Drive mode the motor is run from the Drive output. The DRIVE/BYPASS switch located on the front panel determines operating mode. Within each operating mode are two methods of control; HAND and AUTO. The HAND/OFF/AUTO switch on the front panel determines this control method.

Table 4.1 provides a look at various combinations of the control panel selector switch positions, control inputs to TB1 and the status of the switch selectable options.

Start Up and Operation 4 - 8

For additional influences on the Drive behavior in Drive operating mode, consult Table 5.1 and Table 5.2. These tables explain the settings of Drive parameters required by the Bypass logic (Table 5.1) and those that are also dependent upon the control options present on the unit (Table 5.2). For Example: In the second line of Table 5.2, for a Bypass equipped with no options and switch S1-2 in the off position, the hand mode speed command is based on the setting of d1-02 and the auto mode speed command signal is 0-10VDC.

 Selector Switch Functions

Operating in HAND position - Drive mode:

The Drive can be operated locally from the control panel by first placing the DRIVE/BYPASS switch in DRIVE. Then placing the HAND/OFF/AUTO switch in the HAND position gives the front panel control of the Drive operation. Moving the switch to HAND also provides the run command to the Drive. When placed into HAND mode the Drive begins running at the hand mode speed command.

Operating in AUTO position - Drive mode:

The Drive can be operated remotely by placing the DRIVE/BYPASS switch in DRIVE. Then placing the HAND/OFF/ AUTO switch in the AUTO position gives a remote device (BAS or DDC) control of the Drive. In the AUTO position the Drive will look for a run command contact closure at terminals TB1-3 and TB1-4 on the relay PCB A2. Speed command signal level and source is determined by the parameter settings and the options present in the unit, see Tables 5.1 and 5.2. The AUTO speed command must be wired directly to the Drive terminals A2 and AC, not the control terminal block TB1. Consult Figures 2.7 and 2.8 in Chapter 2, Electrical Installation for correct configuration of the speed command (analog frequency reference).

Operating in HAND position - Bypass mode:

The Bypass can be operated locally from the front control panel by placing the DRIVE/BYPASS switch in BYPASS. In

BYPASS mode the Bypass contactor coil can be energized manually by placing the HAND/OFF/AUTO switch in HAND position. In Bypass mode, moving the HAND/OFF/AUTO switch to HAND causes the motor to run at full speed,

directly “across the line”.

Operating in AUTO position - Bypass mode:

The Bypass can be operated remotely by placing the DRIVE/BYPASS switch in BYPASS and the HAND/OFF/AUTO switch in AUTO. In the AUTO position the Bypass will look for a run command contact closure at terminals TB1-3 and TB1-4 on the relay PCB A2, to control the run/stop status of “across the line” full speed motor operation.

Operating in TEST position - Bypass mode:

TEST position is used to energize the Drive input contactor while operating in the Bypass mode. The only valid use of the TEST position is in Bypass mode. In Drive mode, switching from NORMAL to TEST position will remove the Drive

run command and the motor will stop. In Bypass mode, the test position powers the Drive for programming or other “tests” while keeping it isolated from the motor.

Start Up and Operation 4 - 9

 Switch Selectable Functions

The switch selectable functions, Smoke Purge, Auto Transfer and Remote Transfer represent various methods of transfer- ring from the Drive mode of operation to the Bypass mode. They may be enabled in any combination from none of them to all of them. See Table 4.1 for a summary of some common combinations of these switch selectable inputs.

Smoke Purge: When enabled (switch S105) this function allows a contact closure between terminals TB1-17 and TB1-18 to transfer motor operation to Bypass for a maximum capacity smoke control function. When in smoke purge mode, during emergency fire/smoke situations, the motor overloads and safety interlock circuit are overridden to shift the priority to protecting people rather than equipment. [Note: Smoke purge overrides all other control inputs and selector switches. Smoke purge operation can only be terminated by opening the contact closure at terminals TB1-17 and TB1-18 or by opening the Circuit Breaker (CB1).]

Auto Transfer to Bypass: When enabled (switch S103), the Bypass unit will automatically switch into Bypass mode on a Drive fault. After clearing the Drive fault condition, the function resets by moving the circuit breaker to the OFF position and waiting for the keypad to go blank. CAUTION: Before selecting this function in fan applications, care must be taken to ensure that the ductwork is designed to handle the pressure resulting from full speed operation with the VAV terminal unit dampers at minimum position or closed.

Remote Transfer to Bypass: When enabled (switch S104) this function allows a contact closure from a BAS, between terminals TB1-25 and TB1-26, to transfer motor operation from Drive mode to Bypass mode. This remote transfer to Bypass function overrides the DRIVE/BYPASS manual switch. An open contact causes operation in Drive mode and a closed contact results in Bypass mode.

 Contact Closure Inputs and Outputs

Customer Safety Interlocks Input: Termin a l s TB1-1 and TB1-2 are used as a Drive or Bypass override from the NC contacts of the customer’s safety device series circuit. Anytime all the safety device contacts are closed, the Drive or Bypass will oper ate. When any one of these contacts open, the Drive or Bypass will immediately stop operating. This input is momentary, when a customer safety device contact re-closes, the Drive or Bypass will return to operation.

Auto Mode Run/Stop Contact Input: TB1-3 and TB1-4 are input terminals used for the Run/Stop command when in the AUTO mode. When these input contacts close, the unit will begin running. When the contacts reopen, the unit will cease

running.

BAS Interlock or Drive Enable Input: An open contact at TB1-5 and TB1-6 will override the run command, preventing Drive or Bypass operation until these input contacts are closed. For example this input could insure that the system dampers achieve an operating position before the fan is started in order to protect the ductwork from over pressure.

Drive Run Contact Output: Ter m i n a l s TB1-7 and TB1-8 are an output contact that closes whenever the motor is running in Drive mode. If the Drive is receiving a run command, but a fault condition occurs, this contact will

Bypass Run Contact Output: Ter m i n als TB1-9 and TB1-10 are an output contact that closes whenever the motor is running in Bypass mode. If the Bypass is receiving a run command, but a fault condition occurs, this contact will

Start Up and Operation 4 - 10

Motor Overload or Customer Safeties Fault Contact Output: Terminals TB1-14, TB1-15 and TB1-16 are a Form C set of output relay contacts, N.O. and N.C. that are activated when one of the N.C. contacts of the Customer Safety device input series circuit or the motor overload relay contacts is opened.

120VAC Damper Actuator Output: Output terminals TB1-19 and TB1-20 are provided to energize a damper actuator circuit or solenoid air valve, typically for outdoor air intake dampers. When the motor is stopped, the output voltage is removed in order to close the dampers. Whenever the Drive or Bypass is running, the terminals output 120VAC to power a 40VA damper actuator circuit.

120VAC Control Power Output: Output terminals TB1-21 and TB1-22 are provided to energize additional, customer defined control logic circuits. A maximum of 100VA control power is available, the user must provide the short circuit protection.

Optional Two Motor “OR” Selection Input: Ter m inals TB1-23 and TB1-24 are used only when the “Two Motor OR option” is part of the unit. These input terminals are used for choosing between motor 1 or motor 2 when the optional MOTOR 1/AUTO/MOTOR 2 selector switch is in the AUTO position.

Shaded Areas = Parameter settings required by the Bypass logic. The shaded Bypass Parameter Settings in Table 5.1 document Drive parameter settings, required to interface with the Bypass logic circuit, that have been established at the factory and stored in a dedicated location in the memory as “User Initialization” values (think of it as a “back-up file”).

Table 5.1 is also used to document parameters that have been factory set, for convenience, to typical values for fan and pump applications. These parameters may be changed to meet the needs of the specific application.

If additional parameters are set to the specific needs of the application project, and the system operation has been checked and verified, then the “User Initialization” values should be stored in memory again by selecting and entering “1: Set Default” in parameter o2-03.

When there is a need for re-initialization of the “user” parameters (re-setting to the “User Initialization” values) of the Bypass unit, then a “User Initialization” function should be carried out by selecting “1110: User Initialize” in parameter A1-03. This will re-establish the drive set-up required for the Bypass application and any “user” parameter values that have been stored.

The factory parameter settings required to interface with the bypass logic circuit have also been stored in the digital keypad memory. If there is a need for re-initialization (re-setting to a known factory starting point for trouble-shooting purposes) of the Bypass unit, then the “back-up file” in the digital keypad memory can be copied to the drive. In parameter o3-01 select “2: OP->INV WRITE” to carry out the copy function.

If Serial Communication is to be employed, the following parameter values are essential, see also Appendix D.

 Discussion of Table 5.2 Option-Dependent Bypass Parameter Settings:

Drive Parameter Settings for Various Combinations of Bypass and Options

Notes:

See Appendix D, Communications, for additional information on serial communication.

Hand mode run/stop for Drive and Bypass is always via the front control panel HAND/OFF/AUTO switch.

The HAND/OFF/AUTO switch must be in AUTO position if serial communication is to be used to control the Drive.

For "monitoring only" of Drive parameters and operation, via serial communication, the user needs only to set-up the H5-0X "Serial Com Setup" parameters. All other parameters may remain as they were factory programmed for the Bypass unit and options.

Option L, LonWorks serial communication always requires DIP switch S1-1 (terminating resistor) to be ON. See the LonWorks Option Installation Guide (IG.AFD.20.LONWORKS) for additional parameter setting instructions.

 Options - None; Bypass with no options:

Hand mode speed command from Keypad/Operator. Auto mode speed command input signal, 4-20 mA applied to Drive terminal A2. Auto mode run/stop contact closure for Drive and Bypass applied to terminals TB1-3 and TB1-4.
