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.

P380 - Brake relay output. Only terminals 12 & 13 should be used.
When TorqProve is “enabled” in P600, Relay 1 is dedicated for brake
control only. (All other programmed selections are ignored.)

This “enables” TorqProve and Digital Output 1 will
now control the mechanical brake (Note: This will
cause a Fault 28 which requires user to read the
“Attention” in the User Manual on page C-5)

control TorqProve parameters.

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.
