I apologize for asking question here and not in Electromechanical Industrial Support section, but somehow I get "Access denied" trying to ask there. It seems I miss some permissions?
Anyway, a client is commissioning the system with Parker DC 590p. He wishes to control the motor direction using PLC, but as it appears his PLC has only unipolar analog output (0-5VDC). So he can not send negative reference to DC590p in order to reverse direction.
Is there a simple way to do it? (Configuring a digital input to reverse direction perhaps?)
Could you please advise? Is it possible to reverse direction at all when only unipolar voltage signal is available?
