Example Of Dwell Timer Operation Setting - Panasonic MINAS A4P Series Instruction Manual

3) Setting of step data
• Do not use the rotary axis operation (Rotary) mode together with the incremental operation (Incremen-
tal) or absolute operation (Absolute).
• If a step data set value specified for the rotary axis operation is out of a range between 0 and [movement per
rotation at a rotary coordinate –1], an error code No. 69 (undefined data error protection) is shown.
4) Jog operation
If you use the motor in the rotary axis operation, do not perform the jog operation after homing completes.
The motor may exceed limitation of the current position. If you perform the jog operation by mistake,
execute the homing again.
5) Servo off
Also if the servo has turned off when the motor is used in the rotary axis operation, the motor may exceed
limitation of the current position. Be sure to execute the homing again after the servo turns on.

Example of Dwell Timer Operation Setting

In the dwell timer operation, the motor operates regarding a set value as waiting time. The dwell time operation is
not used independently. This operation is used as waiting time between the points in the block operation.
The chart below shows an example to set the point 1 in the dwell timer after the absolute operation at the
point 2 and perform the relative travel at the point 3 after a specified time has passed.

1. Set the 16-bit positioning parameter in the table above to any value and specify the step parameter
as shown below.
2. Perform homing. (Refer to "Homing Operation" on page 114.)
3. Specify the point 1 after the point 2 operation has completed and connect the strobe signal input
(STB: CN X5 Pin 24) to COM–. Then, a waiting time operation starts. When a waiting time has
passed, the in-operation signal output (BUSY: CN X5 Pin 28) turns on and the next point 3 operation
can be specified.

01 Dwell timer operation (Dwell time)
02 Absolute operation (Absolute)
03 Incremental operation (Incremental)
Caution
1) If a waiting time set value (unit: 10 ms) is larger than 214748364, the waiting time is a maximum of
214748364 x 10 ms.
2) To interrupt the dwell timer operation, input emergency stop or deceleration-and-stop signal assigned by
the multi function input (EX-IN1 and EX-IN2: CN X5 Pin 22 and 25).
