Detailed Drive Operation
This chapter explains PowerFlex 700S drive with Phase II control functions and
application programming in detail. Explanations are organized alphabetically by
topic. Refer to the Table of Contents for a listing of all topics in this chapter.
Accel Time
Parameter 32 [Accel Time 1] sets the rate at which the drive ramps up its output
after a Start command or during an increase in commanded speed (speed change).
The rate established is the result of the programmed acceleration time and the
programmed motor rated speed, set in parameter 4 [Motor NP RPM].
Times are adjustable in 0.0001 second increments from 0.01 to 6553.5 seconds.
Alarms
Alarms indicate conditions within the drive that could affect drive and
application operation. Alarms are selected during commissioning of the drive.
Examples of alarms include: encoder loss, communication loss or other
exceptions within the drive. A complete list of Alarms is included in the
Troubleshooting chapter of the
