Use External Upper/Lower Limit Input (ADDRESS “15”)
To use external upper limit (X08, X0B) and external lower limit (X07, X0A) input signals during
operation, the [Use External Upper/Lower Limit Input] parameter must be set as 1.
Otherwise, it does not detect upper and lower limits and the 4 terminals (X07, X08, X0A, X0B)
will operate as general input contacts.
The External Upper and Lower Limit input signals operate by B contact. In other words, these
external input signals are detected when switching from ON to OFF. And the axis operation
stops immediately.
Be cautious when using a stepping motor because the motor may operate out of phase.
1.5.9
Jog Speed Limit (ADDRESS “16-17”)
Jog operation, a type of manual operation, is driven by a pattern characterized by
acceleration – constant speed – deceleration. The [Jog Speed Limit] parameter configures speed
for the constant speed phase.
1.5.10
Jog Acceleration/Deceleration Time (ADDRESS “18”)
This parameter configures the period of time for the acceleration and deceleration of Jog
operation. The time is assigned by selecting one of the pre-configured values from the
[Acceleration and Deceleration Time, Address 5-8].
Specifies the value from the range of 0 to 3.
1.5.11
Inching Speed (ADDRESS “19”)
Inching operation, a type of manual operation, outputs the specified amount of pulses at the
speed configured in this [Inching Speed] parameter.
Unlike the Jog operation which makes it difficult to move to the correct destination because it is
driven by ON/OFF signals of the start contact, the Inching operation allows a user to reach the
target point by easily setting the desired amount of movement in the Inching command.
Therefore, use the Jog command to move quickly to the vicinity of the work place and then use
the [POSCTRL-Inching command] for fine movement. Or after writing the desired amount of
Inching movement at the Offset 8 of the operation memory area, a user can turn on the Jog and
Inching signal to move to the correct location of the work place.
