L7P

The L7P servo drives from the L7 series represent an advanced solution for positioning applications without the need for an external controller.
The system allows positioning using up to 64 indexes, providing simple and efficient motion control across various industrial applications.

The series includes two models:

L7PA – powered by 3×230 V
L7PB – powered by 3×400 V

L7P drives support power ratings up to 15 kW and can be easily programmed using the free Drive CM software, designed for intuitive use and fast parameter setup.

The servo drive connects to a PC via a USB interface, while communication with other devices (such as controllers or servo systems) is established via Modbus RTU (RS-422).
Using the multi-drop method, up to 31 servo drives can be connected in sequence, enabling efficient synchronized operation in multi-axis systems.

L7P includes a rich set of input and output signals as well as multiple operation modes:

Inputs and outputs:

16 digital inputs
8 digital outputs
2 analog inputs
2 analog outputs

Operating modes:

Indexing operation
Position control
Speed control
Torque control

This series offers a reliable, flexible, and cost-effective solution for automated motion applications requiring precision, speed, and easy control.
