• Teach-in: allows the current position to be saved in an NC block
in setup mode
• Velocity, acceleration and time override
• Collision monitoring via external input
• Simulation mode for testing automatic programs without a motor,
e.g. for recording the position setpoint curve with M function
simulation
♦ Roll feed [830]:
• Automatic cut-to-length feature for presses, punching machines
and cross-cutters in start/stop mode
• Definable velocity/ acceleration profile of traversing curve. This
achieves optimum cycle times with the lowest possible material
wear and slippage.
• Switchover possible between external machine encoder and
motor encoder (at standstill)
• The loop count (number of cut-to-length processes) can be
programmed.
Positioning drives in the following fields are typical applications of
MASTERDRIVES MC:
♦ Woodworking machines
♦ Roll feeds for presses
♦ Packaging machines
♦ Drive tasks in the glass, brick and tire industries and in general
mechanical engineering applications
The following figure shows an example application for the automatic
function on an automatic drilling machine in the woodworking industry:
