1. Introduction
Thank you for your selection of our Piezo Feeder Controller, a digital controller for piezo feeder
(“Controller”).
The piezo feeder is a high-efficiency, energy-saving parts feeder driven by piezoelectric elements.
In combination with the dedicated digital controller, the Controller can be operated easily and
efficiently without requiring any difficult adjustment. Before connecting the piezo feeder and
performing subsequent adjustment, read the Manual carefully to ensure proper use of the excellent
functions of the piezoelectric parts feeder.
2. Before Using
Before unpacking, be careful not to have an impact or vibration on the packing.
Unpack, and check the following:
(1) Isn’t there any damage caused during transport?
(2) Are the rating, capacity and model on the nameplate exactly what you have ordered?
If there is any problem, contact the dealer.
3. Precautions for Safety
Be sure to read the Manual carefully before the installation, operation, maintenance, checkup, etc.
of the Controller to ensure your familiarity with the Controller, safety information and precautions.
In the Manual, the safety precautions are divided into “DANGER” and “CAUTION” according to
their severities.
DANGER
If the Controller is handled improperly, a dangerous situation could be
caused, and the possibility of death or injury is assumed.
CAUTION
If the Controller is handled improperly, a dangerous situation could be
caused, and the possibility of medium or minor injury or partial damage is
assumed.

3/20
DANGER
・Do not service the Controller in the Power-ON status. To avoid an electric shock, be sure to turn
OFF the power supply before starting the service.
・Do not disassemble, remodel or repair the Controller, or an electric shock, a fire or injury could be
caused. For repair, ask the dealer.
・Do not remove the front cover while the Controller is in the Power-ON status, or an electric
shock could be caused.
・Do not put or insert anything in or into the Controller, or an electric shock or a fire could be
caused.
・Do not use the Controller near explosive or flammable gas, or a fire could be caused.
・Do not splash water or liquid, or an electric shock or a fire could be caused.
・If smoke, odor or abnormal noise is emitted or other abnormality is detected, shut down the
Controller immediately. If the Controller is used in the abnormal status, a fire could be caused.
Contact the dealer.
・If the Controller is not operated for a long time, shut down the Controller. If the Controller is left
live as it is, a fire could be caused.
・Connect the power cable and the output cable as instructed in the Manual to avoid an electric
shock and a fire.
・Do not forcedly bend, pull or pinch the power cable or the output cable, or an electric shock or a
fire could be caused.
・Ground the earth terminal and the ground prescribed portions without fail, or an electric shock
could be caused. When working on grounding to a high position or a shaky stand, because fall or
tumble could be caused conditionally, take measures to prevent fall or tumble.
・Do not conduct megger testing for any terminals other than the input terminal.
CAUTION
・Do not use the Controller for an electromagnetic parts feeder or the like.
・Do not turn ON/OFF the power supply frequently, or failure could be caused.
・Do not start/stop the vibrator with an electromagnetic contactor or the like on the output side,
or failure could be caused.
・Do not perform welding work on the feeder side in the Power-ON status.
・Do not perform welding work on the feeder side when the feeder and the Controller are in the
connected status.
・Do not remove the nameplate, the seal, or the like.
・When installing the Controller, hold and fix it firmly and properly.
・Do not transport or carry the Controller in the piled-up status, even in the packed status, or they
could fall, causing injury.
・Do not place the Controller outdoors, in a humid place or in a place with excessive temperature
change.
・Do not pile up the Controller two-tired or more, even in the packed status.
・When disposing of the Controller, dispose it properly as general industrial waste.

6. Input/Output Connections
1) Vibratory feeder drive connection
Confirm that the power supply is in the OFF status. Then, connect the output cable of the
controller to the feeder cable of the piezo feeder.
The connector wire colors should be identified as follows:
※1: Do not connect any feeder other than the piezo feeder made by Sanki.
※2: Do not operate with no load.
※3: Be sure to ground the feeder.
2) Power source connection
Connect the power cable to the single-phase power source.
Do not turn ON the power supply until the whole wiring work is completed.
※1: Be sure to connect to the utility power source.
※2: Be sure to ground the controller.
※3: Do not perform the ON/OFF control on the input power supply side.

3) External signal [in1 Input] connection
The operation/stop of the feeder is operated according to external signal.
When the external signal is not used, set parameter as “Parameter No. 06 = Lo.”
※1. To connect the external signal, the operation panel should be removed.
Confirm that the power supply is in the OFF status. Then, detach the operation panel.
After the connection is completed, attach the operation panel, and then turn ON the power
supply.
The operation panel is connected to the main unit of the controller with a connecting wire.
When attaching/detaching the operation panel, carefully watch out for disconnection or
pinching.
※2. The [+P] –[-P] line can also be used as an outlet of 24VDC, 160mA.
To operate the start/stop of the controller according to external control signal, either method
of non-voltage contact signal or voltage signal (24VDC) can be used.
Make connection to the external control terminal block by using the method ①or ②below
while watching out for the signal to be used and the connection method. When wiring, be careful
not to make mistake about the polarity.
The current of 24VDC and 10mA or less flows between [+S] and [-S]. Carefully select the
connection device (e.g., minute current relay).

9. Added Function
Soft start and soft stop functions
If the rising time or falling time of the piezo feeder should be adjusted, change the settings of
the soft start or soft stop.
To change the settings, set the relevant parameter accordingly.
Parameter No. 0C: Soft start = The time until the set output is achieved after the operation
starts
Parameter No. 0d：Soft stop = The time until the stop is made from the set output after the
stop conditions are met.
The set time is 0.2－9.9 sec. (The default value is invalid.)
10. Initialization of the Set Data 【Returning to the factory setting】
(1) When the Controller is in the Power-OFF status, power ON the Controller by pressing the
Vol ▲key and the Freq ▼key together. The Controller starts in the initialization mode,
and the data display shows “99” in blinking.
(2)In this status, press the Func key and the Set key together long for over 3 sec. All set data
are reset.
(3) Upon the completion of resetting, the data display shows “99” in lighting.
(4)When the Func key is pressed long for over 2 sec, the Controller starts in the factory setting
status.
So is the case with powering OFF and then powering ON the Controller.
※When the above procedure is taken, all set data of parameter, frequency and voltage are
cleared.

14/20
11. Remote Unit (RCU-3A)
When the remote unit is connected, the output voltage of the Piezo controller can be operated
by remote control.
※The frequency to be used for remote control is the set frequency of the main unit of the
controller.
For details of usage of the remote unit, refer to the instruction manual of Remote Unit
(RCU-3A).
1) Function
Variable voltage input: 3 contacts (Select variable resistance or analog input of 0 –5VDC for
each contact.)
Switching input of variable voltage input: 3 contacts (No-voltage contact input)
2) Connection
Connect the remote unit to the terminal block of the main unit of the Controller Px12.
3) Usage
(1) Set the remote unit to valid (Parameter No. 0L:on).
(2) Set [in1] to hi (Parameter No. 06:hi).
(3) Adjust the amplitude by referring to “8. Operation and Amplitude Adjustment Method.”
※The vibration adjusted here is the maximum value that can be operated by the remote unit.
(4) Start operation.
Operate the start/stop according to the control signal from the remote unit side.
When the start/stop operation is made by using the ON/OFF key of the main unit of the
controller Px12, the input on the remote unit side becomes invalid.
