2. Pulse Train Control Mode
This product is capable for the positioning control using the pulse train of IAI actuators.
It is necessary to have the positioning control function able to output the pulse train on the host
controller (PLC).
When using this product for the first time, make sure to avoid mistakes and incorrect wiring by
referring to the procedure below. “PC” stated in this section means “PC software”.
Set the Electronic Gear [Refer to 3.3.4 [1]]
Set the electronic gear ratio based on the
amount of actuator operation per pulse in
Parameters No.65 and 66.
�
Check Item
Is the minimum unit of operation set to the value bigger than the minimum
resolution of the encoder?
Is the fraction of the electronic gear ratio reduced to its lowest terms?
� Yes
Pulse Train Input Output Mode Setting [Refer to 3.3.4 [2]]
Input set the command pulse train input status for the parameter No.63 and No.64.
For the output, set the feedback pulse train output form using the parameters No.68, 69 and 70.
Put Operation Mode Setting Switch to “AUTO” side when the setting is complete.
Servo ON
Input servo ON signal from PLC.
� Check Item
Is the green light [SV]
on the LED status
display ON?
No � Confirm the content of alarm on the teaching
tool such as PC to have an appropriate
treatment.
� Yes
Safety Circuit Check
Check that the emergency stop circuit (or motor
drive-power cutoff circuit) operates normally to turn
OFF the servo.
No �
Check the emergency stop circuit.
� Yes
�
No �
Contact us or our distributor.
� Yes
No �
�
Check Item
Is the orange light [ALM] on
the LED status display OFF?
Connect the teaching tool
such as PC to confirm the
content of alarm and have
an appropriate treatment.
Test Run Adjustment 2
[Operation Mode AUTO]
Output the pulse train from
PLC to the controller and
check the system operation.
� Can the positioning
operation be
performed normally?
� Yes
No �
No � Check the electronic gear ratio setting.
Confirm the command pulse train input mode
setting.
Confirm that there is no problem in the actuator
installation, the actuator operation condition
demands a voltage more than rated voltage, and
appropriate pulse trains are input.
Power Supply and Alarm Check
Connect a teaching tool such as PC, turn the
operation mode setting switch to “MANU” side and
turn the power ON for each unit.
Select [Teaching Mode 1 Safety Speed Activated /
PIO Operation Invalid] in the teaching tool such as
PC.
� Yes
� Yes
Check of Packed Items
Are there all the delivered items?
Installation and Wiring [Refer to Chapter 1, 2.2, 2.3]
Perform the installation of and wiring for the actuator
and controller.
Point Check Item
• Is frame ground (FG) connected?
• Has the noise countermeasure been taken?
�
Test Run Adjustment 1
[Operation Mode MANU]
Check the operation without mounting a
work and set the safety speed invalid on
the teaching tool such as PC, and then
check the operation with a work
mounted.
Check the actuator if it is installed properly, the
condition for use is below the rated values, etc.
Adjust the servo if necessary.
Check Item
Any vibration or
abnormal noise?
No �
� Yes
Is it in condition
without any vibration
and abnormal noise?
Test Run Adjustment 3
Check the system operation
conducted by PLC.
� Yes
