Drive Description

The 1302 Drive is an AC PWM (pulse±width±modulated) inverter that operates on single±or three±phase power as detailed in Figures 2.1 and 2.2. AC input power is applied to the Drive's input terminals. Voltage transients are suppressed by three metal-oxide-varistor (MOV) suppressors. These suppressors keep any input voltage transients within the maximum voltage rating of the input diode module.

The input diode module rectifies the incoming AC voltage into a constant DC bus voltage which is filtered by the DC bus capacitor bank. An internal DC-to-DC power supply uses power from the DC bus and provides the necessary voltages required by the Drive. Under regulator software control, the IGBT (insulated-gate bipolar-transistor) inverter bridge converts the constant DC voltage into an AC PWM waveform. The regulator switches the IGBT inverter bridge using a 4, 6, or 8 kHz carrier frequency (user-selectable). A low carrier frequency maximizes the power rating of the Drive but also increases acoustic noise. A high carrier frequency selection reduces acoustic noise but results in a derating of the Drive's efficiency.

The volts per hertz (V/Hz) regulator governs the open-loop operation of the Drive for adjustable speed performance of AC induction and synchronous motors. The regulator maintains a ratio of voltage to output frequency that provides constant or variable torque across a wide speed range. Drive operation can be adjusted by the parameters entered through the keypad. A microprocessor on the Regulator board controls Drive regulation. See Figure 2.3. The Regulator board accepts internal power feedback signals and an external speed reference signal. The Regulator board provides display data for a four-character display, which is used to indicate Drive parameters, parameter values, and fault codes.

The Drive can be controlled either locally through the keyboard and display (see Chapter 7) or remotely through the terminal strip (see Chapter 5).

The Drive is intended to operate trip-free under any condition. The Drive uses selected signals to extend the acceleration (starting) and deceleration (stopping) rates of the motor when an overcurrent condition occurs. When a fault does occur, however, the regulator generates an instantaneous electronic trip (IET) signal to turn the Drive off (coast-to-rest). The Drive stores an indication or record of the IET fault, which can be viewed on the four-character display. After a fault, the STOP/RESET key or a user-supplied IET RESET pushbutton must be pressed to reset the IET signal and clear the fault from the Drive.

Site Requirements

It is important to properly plan before installing a 1302 Drive to ensure that the Drive's environment and operating conditions are satisfactory. Note that no devices are to be mounted behind the Drive. This area must be kept clear of all control and power wiring. Read the following recommendations before continuing with the Drive installation.

Before deciding on an installation site, consider the following guidelines:

•The area chosen should allow the space required for proper airflow as specified in the next section.

•Do not install the Drive above 1000 meters (3300 feet) without derating output power. For every 91.4 meters (300 feet) above 1000 meters (3300 feet), derate the output current by 1%.

•Verify that the Drive location will meet the following

environmental conditions:

Operating temperature (ambient): 0 to +40°C (32 to 104°F) Storage temperature (ambient): ± 40 to +65°C (±40 to +149°F)

Humidity: 5 to 95% (non-condensing)

•Verify that NEMA 1 Drives can be kept clean, cool, and dry.

•Be sure NEMA 1 Drives are located away from oil, coolants, or other airborne contaminants.

•Verify that the AC power distribution system meets the service conditions specified in table

Wiring Requirements

Verifying the Drive's Power Loss Ratings

When installing a 1302 Drive inside of another enclosure, you should consider the Drive's watts loss rating shown in Table 2.A. This table lists the typical full load power loss watts value under all operating carrier frequencies. Ensure adequate ventilation is provided based on the Drive's watts loss rating.

Evaluate the following areas of Drive wiring before you start the installation: size of available conduit, size of power and control wiring, and motor lead lengths.

Verifying Conduit Sizes

It is important to determine the size of the conduit openings accurately so that the wire planned for a specific entry point will fit through the opening. Figures 4.1 and 4.2 detail conduit opening sizes.

Recommended Power Wire Sizes

Size input power wiring according to applicable codes to handle the Drive's continuous-rated input current. Size output wiring according to applicable codes to handle the Drive's continuous-rated output

current. Table 3.B provides recommended power wiring sizes. Use only copper wire with a minimum temperature rating of 60/75°C.

Table 3.C contains the recommended tightening torque values for all power wiring terminals.

Recommended Motor Lead Lengths

The following motor lead lengths are recommended to reduce line disturbances and noise. See Figure 3.3.

•For applications using one motor, motor lead length should not exceed 76 meters (250 feet).

•For applications with multiple motors, total motor lead length should not exceed 76 meters (250 feet).

When total lead length exceeds 76 meters (250 feet), nuisance trips can occur, caused by capacitive current flow to ground. Note that these capacitively-coupled currents should be taken into consideration when working in areas where drives are running. If the motor lead length must exceed these limits, the addition of output line reactors or other steps must be taken to correct the problem. See Table 3.E. Note that the motor lead lengths shown in Table 3.E are only guidelines. Your application may be restricted to a shorter motor lead length due to:

•The type of wire

•The placement of the wire (for example, in conduit or a cable tray)

•The type of line reactor (For example, with or without LC filters)

•The type of motor

Input Fusing

!

ATTENTION: The 1302 AC Drive does not provide input power short circuit fusing. Specifications for the recommended fuse size and type to provide Drive input power protection against short circuits are provided in Table 3.F. Branch circuit breakers or disconnect switches cannot provide this level of protection for Drive components.

Input line branch circuit protection fuses must be used to protect the input power lines. See Figure 5.A. Table 3.F shows recommended fuse values. These fuse ratings are applicable for one Drive per branch circuit. No other load may be applied to that fused circuit. Note that contactors and circuit breakers are not recommended for AC input line branch protection.

Emergency Stop Installation

!

ATTENTION: The 1302 Drive control circuitry includes solid state components. If hazards due to accidental contact with moving machinery or unintentional flow of liquid, gas or solids exist, an additional hardwired stop circuit is required to remove AC line power to the Drive. When AC input power is removed, there will be a loss of inherent regenerative braking effect and the motor will coast to a stop. An auxiliary braking method may be required.

Depending upon the requirements of the application, the 1302 Drive can be programmed to provide either a coast-to-rest (default) or a ramp-to-rest (user-option) operational stop without physical separation of the power source from the motor. Refer to Chapters 5 and 8 (parameter F-16) for more information on how to program an operational stop.

In addition to the operational stop, users must provide a hardwired emergency stop external to the Drive. The emergency stop circuit must contain only hardwired electromechanical components. Operation of the emergency stop must not depend on electronic logic (hardware or software) or on the communication of commands over an electronic network or link.

Complying with Machinery Safety Standard EN 6024±1:1992

This section applies to users who must comply with machinery safety standard EN 60204-1:1992, part 9.2.5.4, Emergency Stop.

The 1302 Drive coast-to-rest stop is a category 0 operational stop. The ramp-to-rest stop is a category 1 operational stop.

Publication 1302-5.0 Ð January, 1998

1302 Preinstallation 3±9

Motor Considerations

The required external hardwired emergency stop must be either a category 0 or 1 stop, depending on the user's risk assessment of the associated machinery. In order to fully comply with machinery safety standard EN 60204-1:1992, part 9.2.5.4, at least one of the two stop methods must be a category 0 stop.

To obtain motor nameplate horsepower, the Drive's output current rating at the selected carrier frequency should be equal to or greater than motor nameplate current. If the motor nameplate current rating is higher than the Drive's output current rating, derate motor horsepower by the ratio of the Drive's output ampere rating (at the selected carrier frequency) to the motor nameplate current. Note that this approximation is only accurate if the Drive and the motor have nearly the same rating.

Single Motor Applications

Size the drive and motor for the load and speed requirements of the specific application.

The motor's operating current must not exceed the drive's rated output current (at the selected carrier frequency). In addition, the motor's horsepower rating (for example, 1, 2, 3, 5, 7, 10 HP) must not be more than one horsepower range larger than the Drive's horsepower rating.

If the motor will be operated below one-half of its rated speed, the motor overload relay may not protect the motor because of reduced cooling action due to the reduced speed. A motor thermostat, internal to the motor, should be installed to monitor the actual temperature of the windings.

Multiple ± Motor Applications

One Drive can run two or more motors. Adhere to the following requirements to assure correct Drive operation in this case:

•When starting and stopping all the motors at the same time (using the Drive for starting and stopping), the sum of the full-load sine wave currents of all the motors must be equal to or less than the maximum sine wave output current at the selected carrier frequency for the Drive.

F r exa e:	FLA	+	FLA	+	FLA	=	TLA
	(M t r 1)		(M t r 2)		(M t r 3)		(T ta L ad)

Where: TLA <100% rated dr ve ut ut at the se ected carr er freque cy

•When one or more of the motors connected to the output of the Drive are to start independently (using a secondary switching device to add or remove the motor from the circuit):

Any motor that starts or stops while the Drive is running must have a current rating less than 10% of the maximum sine wave current rating of the Drive at the selected carrier frequency.

Publication 1302-5.0 Ð January, 1998

3±10	1302 Preinstallation

The sum of the maximum full-load sine wave currents of all the motors connected continuously to the Drive must be less than the maximum output current rating under all conditions.

Note that each motor requires separate thermal overload protection (for example, a motor relay or a motor thermostat).

Installation

Introduction

This chapter shows how to mount the 1302 Drive and its external components. Also shown are the entry areas for routing wiring in and out of the Drive.

Mounting the Drive

Routing Wires

Attach the drive to the selected flat, vertical surface using the mounting holes provided. Enclosure B and C Drives have four mounting holes. In order to maintain a flat mounting surface and to ensure that bolt tightness is maintained, use washers under the bolt heads. Refer to Figures 3.1 and 3.2 for Drive mounting dimensions. Use the following user-supplied mounting bolts and washers:

•Enclosure B Drives: four M8 (5/16º)

•Enclosure C Drives: four M8 (5/16º)

All wiring should be installed in conformance with the applicable local, national, and international codes (e.g., NEC/CEC). Signal wiring, control wiring, and power wiring must be routed in separate conduits to prevent interference with Drive operation. Do not route wires behind the Drive. Use grommets when hubs are not provided to guard against wire chafing. Figures 4.1 and 4.2 show the wire routing, grounding terminal, and power terminal strips of the 1302 Drives.

ATTENTION: Do Not route signal and control wiring

!in the same conduit with power wiring. This can cause interference with Drive operation. Failure to observe this precaution could result in damage to, or destruction of, the equipment.

Do not route more than three sets of motor leads through a single conduit. This will minimize cross-talk that could reduce the effectiveness of noise reduction methods. If more than three Drive/motor connections per conduit are required, you must use shielded cable. If possible, each conduit should contain only one set of motor leads.

ATTENTION: Unused wires in conduit must be

!grounded at both ends to avoid a possible shock hazard caused by induced voltages. Also, if a Drive sharing a conduit is being serviced or installed, all Drives using this conduit should be disabled to eliminate the possible shock hazard from cross±coupled motor leads. Failure to observe these precautions could result in bodily injury.
