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 terminal of the Power Terminal Block and the -DC test point (refer to the User Manual for location). The voltage must be zero.
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.
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.
- 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
- limit supply voltages within the specification of the drive and,
- 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).
- 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.
Note: These faults are not instantaneous and have shown test results that take between 2 and 12 seconds to occur.
Mount the Drive – Minimum Requirements
Minimum Mounting Clearances
Specified vertical clearance requirements are intended to be from drive to drive. Other objects can occupy this space; however, reduced airflow may cause protection circuits to fault the drive. In addition, inlet air temperature must not exceed the product specification.
Maximum Surrounding Air Temperature
| Enclosure Rating | Temperature Range |
| Open Type, IP 20, NEMA Type 1 & Flange Mount | 0 - 50°C (32 - 122°F) |
| IP54, IP 66 & NEMA Type 4X/12 | 0 - 40°C (32 - 104°F) |
Some drives are equipped with an adhesive label on the top of the chassis. Removing the adhesive label from the drive changes the NEMA enclosure rating from Type 1 Enclosed to Open Type.

,Troubleshooting – Abbreviated Fault & Alarm Listing
For a complete listing of Faults and Alarms, refer to the PowerFlex 70 User Manual.
| Fault | No. | Type(1) | Description | Action |
| Auxiliary Input | 2 |  | Auxiliary input interlock is open. | Check remote wiring. |
| 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 200-250% of the drive continuous rating. | Check for excess load, improper DC boost setting. DC brake volts set too high. |
| IR Volts Range | 77 | "Calculate" is the autotune default and the value determined by the autotune procedure for IR Drop Volts is not in the range of acceptable values. | Re-enter motor nameplate data. | |
| FluxAmpsRef Rang | 78 | The value for flux amps determined by the Autotune procedure exceeds the programmed [Motor NP FLA]. |
