If NegativeEnable (Negative Direction Enable) changes to TRUE while PositiveEnable (Positive Direc-
tion Enable) is TRUE, the axis starts jogging in the negative direction. In this case, the axis will not jog
in the positive direction even if NegativeEnable (Negative Direction Enable) changes to F
ALSE.
To jog the axis in the positive direction, change PositiveEnable (Positive Direction Enable) to FALSE,
and then back to TRUE again.
The same operation applies to the opposite case.
The following example shows an operation example when NegativeEnable (Negative Direction Ena-
ble) changes to TRUE after PositiveEnable (Positive Direction Enable) changes to TRUE.
