Tuning The Motor For Torque Prove Applications
It is possible to use Autotune to tune the motor (see Tune the Current Regulator
on page
and Tune the Speed Regulator on page
). However, it is
recommended that the motor be disconnected from the hoist/crane equipment
during the routine.
Crane Setup with Encoder/Resolver Feedback
These setup instructions assume the following.
•
The drive and motor size have been carefully selected
•
The drive parameters are at the factory defaults
•
Programming is done with DriveExplorer or DriveTools SP software
•
Crane control is done via Run Forward / Run Reverse inputs
•
The mechanical brake control is wired to Relay Output 2
•
If a resolver will be used, the drive must have a Resolver Feedback option
module installed
•
The encoder/resolver is mounted on the back of the motor (not behind
the gearbox)
•
The encoder, if used, meets this specification: Quadrature differential
(A, A-, B, B-), Line driver output, Minimum 1000 PPR 5V or 12V signals
(12V preferred)
ATTENTION: To guard against personal injury and/or equipment damage
caused by unexpected brake release, verify the digital output used for brake
connections and/or programming. The PowerFlex DC drive will not control
the mechanical brake until TorqProve is enabled. If the brake is
connected to a digital output, it could be released. If necessary, disconnect
the digital output until wiring/programming can be completed and
verified.
ATTENTION: Loss of control in suspended load applications can cause personal
injury and/or equipment damage. Loads must always be controlled by the drive
or a mechanical brake. Parameters 1100…1114 are designed for lifting/torque
proving applications. It is the responsibility of the engineer and/or end user to
configure drive parameters, test any lifting functionality and meet safety
requirements in accordance with all applicable codes and standards.
