1.6 Controlling by an external PLC
The drive controller can be controlled either directly by floating contacts or by an
external PLC.
If the control inputs are controlled by an external PLC, positive switching PLC
outputs are required and the voltage levels may not exceed 30 VDC.
1.7 Programming the internal PLC
The drive controller contains an integrated mini-PLC, which is provided with a
standard programming as factory default. However you can adapt the system to
your requirements in an optimum way by using your own PLC-programs.
Application specific PLC-programs can be developed with the programming
software BeCon according to IEC 1131 and loaded into the drive controller via
the serial interface. Any motor parameters may be set within the PLC-programs
(limit of motor current, speed of rotation, ramp function, IxR compensation).
In addition the PLC programming allows to assign the potentiometers P1 to P3 to
the motor parameters in any way.
If you have questions concerning the PC software BeCon please contact directly
bebro electronic. You can download a free test version of BeCon from the bebro
homepage (http://www.bebro.de).
