9 AT T E NT IO N : 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 , Guarding Against Electrostatic Damage or any other applicable ESD protection handbook.!AT T E NT IO N : 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.!AT T E NT IO N : 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.

10 Failure to comply may result in personal injury and/or equipment damage.!AT T E NT IO N : 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 Installation Instructions for location). The voltage must be Automation Publication PFLEX-RM001H-EN-P - June 201311 Chapter 2 Detailed Drive OperationThis chapter explains PowerFlex drive functions in detail. Explanations are organized alphabetically by topic. Refer to the Table of Contents for a listing of Time[Accel Time 1, 2]The Accel Time parameters set the rate at which the drive ramps up its output Frequency after a Start command or during an increase in command Frequency (speed change). The rate established is the result of the programmed Accel Time and the Minimum and Maximum Frequency , as follows:Two accel times exist to allow the user to change acceleration rates on the fly via PLC command or digital input.
