**) Reversed direction of rotation. Indicate direction of rotation .
To avoid tacho errors coming up when running with high-speed rotation in
combintaiton with a pulse generator of bad symmetry, capacitor C23 on the motor
board A10 in PROTIG 315 should be replaced.
The capacitor C23 can also be replaced on motor board A09 (for wire feed) and A08
(for weaving) to get a more linear operation.
C23:
