Crane Setup - Encoderless
These setup instructions assume the following.
•
Drive and motor size have been carefully selected
•
External braking 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
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
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.
