± 10V-In Manual jog pos-
itive
When high (above 5V), the drive will travel with jog-
ging speed (P1916) and ramp (P1917) in the positive
direction. When low (below 5V), the drive will ramp
down and stop if no other motion procedure is acti-
vated. Jog positive has higher priority than Jog neg-
ative Not used in fieldbus mode.
54
± 10V-In Manual jog neg-
ative
When high (above 5V), the drive will travel with jog-
ging speed (P1916) and ramp (P1917) in the nega-
tive direction. When low (below 5V), the drive will
ramp down and stop if no other motion procedure is
