Siemens alarm 14800: Channel %1 block %2 programmed path speed less or equal to zero

What it means

The effective path feedrate for the traversing block is zero or negative, which cannot produce motion. A zero or invalid F value became modal, or an expression assigned a non-positive feed. Program a positive feedrate appropriate to the operation.

Likely causes

• F0 or negative F programmed directly
• Feed computed from R-parameters/variables evaluating to zero
• Feed reset by mode or cycle changeover before the move
