ACS380 Direction
Hi there,
I have ACS380 that i need to write a Control word for forward and reverse. I can start and stop the drive sending word-- 1150 (STOP) and 1151 ( RUN) to DATA out 1 and DATA out 2 of FBA . I was wondering what CW to what parameters should i write to so that i can be able to change the direction of the motor. Also, what parameters should i set on the drive? Any demos, documents, comments would be highly appreciated.
Thanks
ROB

Greetings,
Generally CW is used for Start/Stop drive.
If you want to change direction of motor you can use reference setpoint with sign.
For example if you set -50.Hz your drive starts to run Counter-Clockwise direciton, if you set 50.0 Hz. your drive start to run Clockwise direction.
Hope it helps you.

Hi
I suppose you are using ProfiBus or ProfiNet, but I think by heart that even EtherCat has the same behavior. As Titus correctly wrote to you, the CW is used for start and stop commands, and possibly reset on the drive.
The speed reference is written to the next word and this parameter in the ACS380 is written as shown in the image below, in FBA data out 2. As an example, in this application, a torque reference value is also written, followed by the acceleration and deceleration values.
