ABB VFD Relay Output Setting with Wiring Diagram and Parameter Settings 

Thank you so much 👍

Push button se ek me speed increase ka di ek pick karna hoga aur ek pb se speed decrease keliye dusra di pick karna hoga hardware wiring me. Uske baad Speed Reference Selection setting me motor protection meter select karna padega aur increse kounsa di decrease kounsa di usko define karna padega. Tab jake chal jayega

Fault - Fault hone se Relay output kya hoga ? Fault(-1) isko fault inverse bhi bolte bain - iska matlab fault jab nahi hai tab relay output kya hoga

Potential free means isolated Contact of Relay. Only relay coil attached with VFD control card but it's auxiliary contacts are isolated. It has common, No, Nc point. If you connect 24 vdc to common pin you will get back it at No pin after relay pickup. Potential free means you can use any available power supply by its auxiliary contacts it has no link to VFD internal 24volt.
