In order to prevent damage to the product caused by improper operation, please
pay attention to following points when using:
N31 piezo motor is used as much as possible in dust-free, oil-free, lubricant-free
environments;
Since the product adopts flexible structure design, it is recommended that the load
not exceed the bearing capacity of the product. Pay attention to the torque when
loading. Do not twist or twist the load surface to avoid damage to the structure;
Do not disassemble the product to avoid product damage;
Avoid stretching and bending the cable interface to prevent damage to the cable;
Please use the dedicated cable provided by us to connect the piezo motor and piezo
controller;
Please do not use cable extension wire, if need longer cable, please contact us.
Temperature changed and pressure will charge the piezo motor. Piezo motor
will remain charged for a period of time disconnected from the controller, so the
operator should pay attention when using it:
Do not disassemble N31 piezo motor;
Discharge N31 piezo motor before installation, it could be achieved by connecting
to the controller;
Do not pull out the controller during operation;
Before using, please check whether the connecting wire of the product is in good
condition, whether the product and the controller are effectively protected from
grounding, in case of danger, please strictly regulate the operation during operation,
do not touch it (up to 150V voltage) after power on.
2. Safety Guide

N31 Installation diagram
Before installation, first check the safety, such as whether the cable is damaged or broken,
and whether the power supply has grounding protection.
5.1 Installation and announcement
1. Ensure that the installation plane is relatively flat.
2. Fix the platform with M3 screws and tighten it.
3. Install load, properly tighten, load should not exceed 5kg.
N31 installation diagram is shown below:

5.2 Load
When installing the load, ensure that the load mass is less than the max load of the N31,
and install the load as much as possible at the center of the moving surface.
The correct placement of the load is shown below:
Load applied to the center of piezo motor

6
N31 Linear Piezo Motor User Manual
Try not to let the load center of gravity exceed piezo motor
Do not load longer loads and add to the side of the piezo motor
It is forbidden to load the load on one side of the piezo motor, which would cause serious
damage to the product, as shown in the following figure:
For protection, we don't recommend the load is too high. If it is used a higher load, please
reduce the position center of the load gravity.
The error placement method is as follows:
If the screws used in tightening and connecting are too long, the screws will not be
installed or some of screws will leak out, which will scratch the piezo motor and affect the
motion accuracy. If the screws are too short, the connection will not be compact and easy
to loosen. Looseness could damage the internal structure of the piezo motor.
We recommend using the connection method shown below:

Correct connection
Please do not connect as shown below:
Incorrect connection
Note:
Slowly tighten the load when installing it, and the torque should not be too large to
avoid damage to mechanism.
Avoid stretching and bending cables.
Please connect N31 and controller with special cable provided by CoreMorrow.
Please do not extend the cable without authorization, please contact us if you need
a longer cable.
