3.2 Jog Stepping
To perform jog stepping, first write the target velocity, acceleration time, deceleration
time and other required parameters from the CPU module, and then change the state of
the Positive-direction Jog Stepping output relay or Negative-direction Jog Stepping
output relay from off to on. To stop job stepping, turn off the corresponding output relay.
During jog stepping, any error in the positive-direction or negative-direction limit value
will not be detected (no error occurs). If the operation range of the positioning module is
exceeded, however, a pulse overflow error occurs.
The acceleration/deceleration curve can be either trapezoidal or of S-shape, and the
acceleration and deceleration times can be set independently.
