TEKCELEO WLG-30-R User manual

WLG-30-R with embedded encoder
Thank you for trusting Tekceleo and buying this piezoelectric motor.
Please follow the instructions below before using this WLG-30-R motor
Inside the box
•WLG-30-R
•WLG-30 ECU
•US adapter plug
•7,5V 2A Power Supply
Power Up Motor Control Speed Control
In order to control the speed and turn on the motor,
connect the ground pin 2 and the speed pin 1 to a
voltage generator (See the figure 2 and 4). If the speed
pin is not connected, the motor will not rotate.
In order to turn on/ turn off the motor,
activate the on/off Switch (ON/OFF).
To change the direction of the rotation,
activate the CW/CCW Switch (DIRECTION)
(See figure 1).
Connect the power supply into an
electrical outlet.
Jumper Settings
In order to control the motor via the manual
switches, place the jumpers in the Switch
Control position (see figure 3).
In order to control the motor via pin 3 and 4,
place the jumpers in the External Control on
pins 3 and 4 position (see figure 3 and 4).

To operate continuously, the motor needs to dissipate heat. It is advisable to mount
it on a metal cooling plate. Performances are ensured as long as the temperature of
the motor remains under 40 degrees (see details page 5)

CHARACTERISTICS VALUES
On / Off response time (Pin 3) < 500 µs
Speed change response time < 50 ms
Closed loop position controller (see figure below) P control proportional
In case you need to control the position of the motor :
In order to take advantage of the on / off response time of the motor, it is preferable to
send a 0V on pin 3 once the motor has reached its position (see figure below)

Mounting recommendation
WLG-30-R motor can perfectly transmit the mechanical power required if its assembly respects two constraints
We also recommend to fix the piezoelectric motor on a metal plate to dissipate the heat generated by the motor.
Optimal size is aluminum plate with the specified dimensions : 30 x 30 x 5 mm
Make sure to screw the motor using the right screw length (M3x0,5 –3 mm deep MAX in the motor)
Please respect the recommended tightening torque for M3 screws : 0,9 Nm
WLG-30-R with embedded encoder
The motor shaft must absolutely not be loaded by radial load more than specified : 10 N
The motor must be mounted on cooling plate designed in order to better dissipate the heat emanating from the motor
We highly recommend to use a flexible
coupling between the WLG-30 motor and
the load in order to ensure performances.
Please find on the table the main
characteristics to respect.
