1 INTRODUCTION
1.1 General information
This manual describes the installation and commissioning of the frequency converter for SPD
brushless motors.
Please, read all chapters
carefully
.
1.2 Product description
The SPD is a digital frequency converter for brushless motors. The operator interface based
on parameters makes it easy to configure the converter. Configurations of different kinds
make suitable it for many applications.
The SPD 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 SPD 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.
1.3 Main software features
The following functions have been implemented in the basic software of the SPD:
Speed controller
Advanced manager of torque limits
Management of speed windows
Torque motor control
Torque control with speed control overlaying
Positioning with trapezoidal Speed profiles
Provides the functions of an electrical shaft with variable ratio and phase correction
Electronic cam
Simulates a stepper motor
It is provided with an internal PLC for programming the Serial interface RS422-485
integrated can bus interface inputs/outputs: each drive has two independent nodes.
