Appendix C Application Notes
Crane Set up with Encoder
Feedback
These setup instructions assume the following.
• Drive and motor size have been carefully selected
• External brake resistor has been properly sized
• The drive is at factory defaults.
If not, unplug the output relay terminal block and issue a reset to factory
defaults for the HOST and all PORTS. Plug terminal block back in.
• Programming is done via DriveExecutive™ or DriveExplorer™
• Crane control is done via Run forward / Run Reverse inputs
• Mechanical brake control is wired to Output Relay 0
• The drive is equipped with an incremental (20-750-ENC-1) or dual
incremental encoder board (20-750-DENC-1)
• The encoder is mounted on the back of the motor (not behind the
gearbox)
• Encoder specification: Quadrature differential (A, A-, B, B-), Line driver
output, Minimum 1000PPR 5V, or 12V signals (12V preferred)
ATTENTION: Loss of control in suspended load applications can cause personal
injury and/or equipment damage. The drive or a mechanical brake must always
control the loads. Parameters 1100…1113 are designed for lifting/torque prove
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.
