Precautions in Operation
1. Use the following teaching tools.
Use the PC software and the teaching pendant stated in the next clause as the applicable for
this controller.
[Refer to 1.1.2 Teaching Tool.]
2. Backup the data to secure for breakdown.
A non-volatile memory is used as the backup memory for this controller. All the registered
position data and parameters are written into this memory and backed-up at the same time.
Therefore, you will not usually lose the data even if the power is shut down. However, make
sure to save the latest data so a quick recovery action can be taken in case when the controller
is broken and needs to be replaced with another one.
How to Save Data
(1) Save the data to CD-R or hard disk with using the PC software
(2) Hard-copy the information of position tables and parameters on paper
3. Set the operation patterns.
This controller processes 9 types of control logics (including 8 types of PIO patterns and pulse
train control) to meet various ways of usage, and changes the role of each PIO signal following
the selected control logic.
The setup can be performed by using the operation mode change switch or parameter No.25
“PIO pattern selection” on the front panel.
[Refer to Chapter 3 Operation and Chapter 8 I/O Parameter.]
The PIO pattern is set to “0” (Standard Type) when the unit is delivered. Set the operation
pattern setting to the logic that suits to your use after the power is turned on.
4. Clock Setting in Calendar Function
There may be a case that Alarm Code 069 “Real Time Clock Vibration Stop Detect” is issued at
the first time to turn the power on after the product is delivered. In the case this happens, set the
current time with a teaching tool.
If the battery is fully charged, the clock data is retained for approximately 10 days after the
power is turned OFF. Even though the time setting is conducted before the product is shipped
out, the battery is not fully charged. Therefore, there may be a case that the clock data is lost
even with fewer days than described above passed since the product is shipped out.
5. In pulse train control mode, actuator operation is unavailable through serial
communication.
In the pulse train control mode, the actuator operation is unavailable through serial
communication. (The field bus specification does not meet the pulse train control mode.)
However, it is possible to monitor the current status.
Warning :
Please note it is very risky when the control sequence and PIO pattern setting do not match to
each other. It may not only cause the normal operation disabled, but also may cause an
unexpected.
