Simple FWD-RWD cycle - Possible with BLE2?

Hello,
Question from a newbie: I'm using a BLE2 unit on a low speed gear pump.
I would like to make a simple dosing system driven by a proximity sensor, but with a twist:
When the sensor is on the motor will run CW for a limited time, when is off it will run CCW for half a second or similar. Then it stops until triggered again. So it's a cycle, like: 2 sec CW, 0,5 sec CCW (at a pre determined speed), stop.
Therefore there's some programming to do. I'm looking at the provided software but it seems I can only switch on and off the motor with the sensor, but not much more.
Do I need a more complex PLC? Is there something suitable and easy to program in Orientalmotor range?
Is something doable with an Arduino or similar?

Thank you!

Hello,

For the BLE2 to perform this operation you will need a controller to turn on the CW and CCW inputs when using 2-wire mode. If you using 3-wire mode 1 input would become CW/CCW but you would start the motion by have the START/STOP and RUN/BRAKE inputs on. Then it would rotate CW when off and CCW when on. With 3-wire mode you can stop the motion by turning off the RUN/BRAKE input. The timing charts are referenced on pages 28 for 2-wire mode and page 29 for 3-wire mode.

For our other series that can perform positioning operations like BX2, AR, RK2 and AZ you can program the position you want to move in steps and link a second movement with a dwell time between them but this would be based on positions not on time.
