2. Pulse Train Control Mode (for Pulse Train Type)
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.
ψ
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?
φ Yes
Pulse Train Input Output Mode Setting [Refer to 3.3.4 [2]]
Set the command pulse train input status for the parameter No.63 and No.64.
Put Operation Mode Setting Switch to “AUTO” side when the setting is complete.
Servo ON
Input servo ON signal from PLC.
ψ
Check Item
Is the Controller Status
Display LED turned ON
in green [SV]?
No ψ
Confirm the content of alarm on the teaching
tool such as PC to have an appropriate
treatment.
φ Yes
Safety Circuit Check
Check that the emergency stop circuit (or motor
drive-power cutoff circuit) operates normally to turn
OFF the servo.
No ψ
Check the emergency stop circuit.
ω Yes

No ψ
Contact us or our distributor.
ω Yes
No ψ
ψ
Check Item
Is the Controller Status
Display LED turned 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.
ψ
No ψ
No ψ
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 unit.
Select [Teaching Mode 1 Safety Speed Activated /
PIO Operation Invalid] in the teaching tool.
ω Yes
φ 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?
ψ
Test Run Adjustment 1
[Operation Mode MANU]
Check with a teaching tool such as the
PC with no work being loaded, and check
the operation range with JOG operation
with the work being loaded.
Check if there is any problem in the way of
actuator mount.
Check Item
Is there any risk of
interfering with
peripheral
equipment?
Yes ψ
ω No
Can the positioning
operation be performed
normally?
ω Yes
ω Yes
Is it in condition without
any vibration and
abnormal noise?
Test Run Adjustment 3
Check the system operation conducted by PLC.
PIO Pattern Settings
Set the used PIO pattern to Parameter No.25.
