1 INTRODUCTION
1.1 General information
This manual describes the installation and commissioning of the frequency converter TWIN-N/SPD-
N for brushless motors.
Read carefully all the sections.
1.2 Product description
The TWIN-N/SPD-N is a digital frequency converter for brushless motors and asynchronous motors
with feedback. The operator interface based on parameters makes it easy to configure the converter.
Configurations of different kinds make suitable it for many applications.
The TWIN-N converter allows controlling two brushless motors with a single converter. This feature
allows saving space into the electric panel in multi-axis configurations. Actually, they are two
different converters that can be used in a totally independent way.
The SPD-N drive is the version to single axis.
The drive features a series of integrated auxiliary functions that allow minimising the control
electronics in the applications, with a considerable cost saving.
It uses widely diffused industrial programming standards and guarantees a high degree of freedom in
selecting inputs and outputs. The drive also offers the possibility to develop additional functions that
are not included in the basic functionality of the converter such as gain correction for loops based on
speed or space, monitoring the used torque for tool life control, etc.
It can be configured through the serial keypad, the serial line or the CAN bus
