an external PLC, positive switching PLC outputs are required and the voltage
levels may not exceed 30 VDC.
3 Start-up and operation
The following descriptions relate to the standard programming. When starting up
and operating the drive controller perform the procedures described in the
following sections. For an application specific programming use the same
procedures.
3.1 Setting the supply voltage range
The drive controller can be driven with a supply voltage of 10 to 30 VDC. The
used supply voltage must be set on the circuit board with a jumper. For mounting
position of the jumper refer to page 26.

1 - 2: Supply voltage 18 VDC up to 30 VDC
2 - 3: Supply voltage 10 VDC up to 18 VDC
Jumper Position
3.2 Operation display via LED
The LED of the drive controller displays the operation mode:
LED flashes approx. once per second: Normal operation
LED flashes approx. four times per second: EEPROM failure
While the drive controller is sending data to the connected PC programming
software BeCon the LED flashes in the rhythm of the sent data.
If a failure is detected the motor is stopped. A failure occurs if the power output
stage is overheated or in case of a short-circuit. You have two possibilities to
reset the failure:
•
Switching off and subsequently switching on the supply voltage of the drive
controller or
•
off-signal and subsequently on-signal at release input.
