Operating Temperatures
PowerFlex 700 drives are designed to operate at 0° to 40°C ambient.
To operate in installations between 41° and 50°C, see Table B.

⁽¹⁾ To remove vent plate (see Figure 3 for location), lift top edge of plate from the chassis. Rotate the plate out from the back plate.

Removing the adhesive label from the drive changes the NEMA enclosure rating from Type 1 to Open type.

Power Wiring

Wire Recommendations
A variety of cable types are acceptable for drive installations. For many installations, unshielded cable is adequate, provided it can be separated from sensitive circuits. As an approximate guide, allow a spacing of 0.3 meters (1 foot) for every 10 meters (32.8 feet) of length. In all cases, long parallel runs must be avoided. Do not use cable with an insulation thickness less than or equal to 15 mils (0.4mm/0.015 in.). See Table D.

Unshielded
THHN, THWN or similar wire is acceptable for drive installation in dry environments provided adequate free air space and/or conduit fill rates limits are provided. Do not use THHN or similarly coated wire in wet areas. Any wire chosen must have a minimum insulation thickness of 15 Mils and should not have large variations in insulation concentricity.

Shielded/Armored Cable
Shielded cable is recommended if sensitive circuits or devices are connected or mounted to the machinery driven by the motor. See Table D. For further information on acceptable and unacceptable cable types, refer to "Power Wiring" in the PowerFlex 700 User Manual.

⁽¹⁾ Maximum/minimum sizes that the terminal block will accept - these are not recommendations.
⁽²⁾ External control power:
UL Installation - 300V DC, ±10%, Non UL Installation - 270-600V DC, ±10%.
0-3 Frame - 40 W, 165 mA, 5 Frame - 80 W, 90 mA.

Power & Ground Wiring

Control Wiring

• Always use copper wire.
• Wire with an insulation rating of 600V or greater is recommended.
• Control and signal wires should be separated from power wires by at least 0.3 meters (1 foot).
• I/O terminals labeled "(–)" or "Common" are not referenced to earth ground and are designed to greatly reduce common mode interference. Grounding these terminals can cause signal noise.

ATTENTION: Configuring an analog input for 0-20mA operation and driving it from a voltage source could cause component damage. Verify proper configuration prior to applying input signals.

ATTENTION: Hazard of personal injury or equipment damage exists when using bipolar input sources. Noise and drift in sensitive input circuits can cause unpredictable changes in motor speed and direction. Use speed command parameters to help reduce input source sensitivity.

⁽¹⁾ If the wires are short and contained within a cabinet which has no sensitive circuits, the use of shielded wire may not be necessary, but is always recommended.

⁽¹⁾ Maximum/minimum sizes that the terminal block will accept - these are not recommendations.
⁽²⁾ Not available with Standard Control option.

Hardware Enable Circuitry

(Vector Control Option Only)
By default, the user can program a digital input as an Enable input. The status of this input is interpreted by drive software. If the application requires the drive to be disabled without software interpretation, a "dedicated" hardware enable configuration can be utilized. This is done by removing a jumper and wiring the enable input to "Digital In 6" (see below).

1. Remove the I/O Control Cassette & cover as described in the User Manual.
2. Locate & remove Jumper J10 on the Main Control Board (see diagram).
   
3. Re-assemble cassette.
4. Wire Enable to "Digital In 6" (see Figure 4).
5. Verify that [Digital In6 Sel], parameter 366 is set to "1, Enable."

Motor Overload

7

Internal electronic overload trip. Enable/Disable with [Fault Config 1].

An excessive motor load exists. Reduce load so drive output current does not exceed the current set by [Motor NP FLA].

OverSpeed Limit

25

Functions such as Slip Compensation or Bus Regulation have attempted to add an output frequency adjustment greater than that programmed in [Overspeed Limit].

Remove excessive load or overhauling conditions or increase [Overspeed Limit].

SW OverCurrent

36

Drive output current has exceeded the 1ms current rating. This rating is greater than the 3 second current rating and less than the hardware overcurrent fault level. It is typically 200250% of the drive continuous rating

Check for excess load, improper DC boost setting. DC brake volts set too high.

DB Resistance

69

Resistance of the internal DB resistor is out of range.

Replace resistor.

IR Volts Range

Manually Clearing Faults

Read the General Precautions

ATTENTION: This drive contains ESD (Electrostatic Discharge) sensitive parts and assemblies. Static control precautions are required when installing, testing, servicing or repairing this assembly. Component damage may result if ESD control procedures are not followed. If you are not familiar with static control procedures, reference A-B publication 8000-4.5.2, "Guarding Against Electrostatic Damage" or any other applicable ESD protection handbook.

ATTENTION: An incorrectly applied or installed drive can result in component damage or a reduction in product life. Wiring or application errors, such as, undersizing the motor, incorrect or inadequate AC supply, or excessive ambient temperatures may result in malfunction of the system.

ATTENTION: Only qualified personnel familiar with adjustable frequency AC drives and associated machinery should plan or implement the installation, start-up and subsequent maintenance of the system. Failure to comply may result in personal injury and/or equipment damage.

ATTENTION: To avoid an electric shock hazard, verify that the voltage on the bus capacitors has discharged before performing any work on the drive. Measure the DC bus voltage at the +DC & –DC terminals of the Power Terminal Block (refer to the User Manual for location). The voltage must be zero.

ATTENTION: Risk of injury or equipment damage exists. DPI or SCANport host products must not be directly connected together via 1202 cables. Unpredictable behavior can result if two or more devices are connected in this manner.

ATTENTION: The "adjust freq" portion of the bus regulator function is extremely useful for preventing nuisance overvoltage faults resulting from aggressive decelerations, overhauling loads, and eccentric loads. It forces the output frequency to be greater than commanded frequency while the drive's bus voltage is increasing towards levels that would otherwise cause a fault. However, it can also cause either of the following two conditions to occur.

1. Fast positive changes in input voltage (more than a 10% increase within 6 minutes) can cause uncommanded positive speed changes. However an "OverSpeed Limit" fault will occur if the speed reaches [Max Speed] + [Overspeed Limit]. If this condition is unacceptable, action should be taken to:
   1. limit supply voltages within the specification of the drive and,
   2. limit fast positive input voltage changes to less than 10%.
      Without taking such actions, if this operation is unacceptable, the "adjust freq" portion of the bus regulator function must be disabled (see parameters 161 and 162).
2. Actual deceleration times can be longer than commanded deceleration times. However, a "Decel Inhibit" fault is generated if the drive stops decelerating altogether. If this condition is unacceptable, the "adjust freq" portion of the bus regulator must be disabled (see parameters 161 and 162). In addition, installing a properly sized dynamic brake resistor will provide equal or better performance in most cases.

These faults are not instantaneous. Test results have shown that they can take between 2-12 seconds.

ATTENTION: A contactor or other device that routinely disconnects and reapplies the AC line to the drive to start and stop the motor can cause drive hardware damage. The drive is designed to use control input signals that will start and stop the motor. If an input device is used, operation must not exceed one cycle per minute or drive damage will occur.

ATTENTION: The drive start/stop/enable 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 may be required to remove the AC line to the drive. An auxiliary braking method may be required.

ATTENTION: If using Output Contactors, refer to the "Output Contactor Precaution" statement of the PowerFlex 700 User Manual.
