Drive Application Software Application Set Application Set Title Drive Product File Name for (AS) Date / Revision TorqProve™ - Overhead Crane, Encoderless PowerFlex® 700 Vector Control (Series B) AS PF700 Overhead Crane no enc TorqProve.doc 4/13/05 - 01 Attention: This document and related file(s) are designed to supplement configuration of the listed drive product. The information provided does not replace the drive products user manual and is intended for qualified personnel only. Description: TorqProve programming of an overhead crane without an encoder. PLC was used to send digital signals to drive for starting and stopping only. Reference Application Brief Publication: PowerFlex 700 App Brief-Overhead Crane(Encoderless), 20B-AP002A-EN-P – April 2005 Limitations: Care should be taken with any encoderless lift application. It should only be used where personal safety is not a concern. It does not offer as much protection as an application with encoders. Please review the Application Notes in the User Manual for additional information. Options & Notes: ATTENTION: To guard against personal injury and/or equipment damage caused by unexpected brake release, verify the Digital Out 1 brake connections and/or programming. The default drive configuration energizes the Digital Out 1 relay when power is applied to the drive. The PowerFlex 700 drive will not control the mechanical brake until TorqProve is enabled. If the brake is connected to this relay, it could be released. If necessary, disconnect the relay output until wiring/programming can be completed and verified.

Default - Not active in Sensorless Vector Default - Not active in Sensorless Vector Default Default - Not used in encoderless mode Approximately 3 times slip RPM Default Default - Not used in encoderless mode Default - Not used in encoderless mode Default - Not used in encoderless mode Default – Not used in this application Encoderless notes: • Though it was not required in this application since the user is always running at 1500RPM, it is always good to set P81 [Minimum Speed] to two or three times the slip frequency when in encoderless mode. (Example: A 1740 RPM motor has 2 Hz of slip so set Minimum Speed to 4-6Hz.) • It is also desirable (but not 100% necessary) to set P606 [Float Tolerance] to one to three times the slip frequency when in encoderless mode. This should be set a value that approaches this value but still gives acceptable performance. AS_PF700_Overhead_Crane_no_enc_TorqProve.doc Form Revision – A Page 2 of 2
