Please read these notes carefully before powering up the drive
Simbols security standard
Caution
Warning of dangerous current present
In case of doubt or in any case you don’t know as to behave yourself, before access to the
drive, power off the device and wait until all the leds are turned off.
May you have attention when you touch the drive because it may be hot.
Danger Sign
All the circuits in the Drive are potential sources of severe electrical shock, so follow these
rules to avoiding possible personal injury.
- Power off the drive and wait until all the leds are turned off before touching, removing,
connecting or any other critical action.
- Never disconnect any connectors before powering down the drive

Description
Operation mode
General characteristic
Closing the velocity feedback loop to motor may be done in several different ways to accommodate
most applications. This types of velocity feedback are available with DC brush motors.
Velocity feedback
• DC motor with encoder
• DC motor with internal PWM (Armature)
• DC motor with tachogenerator
This is a drive capable to drive DC brush motors, up to 3Nm. It's a High Performance full four
quadrant drive servo amplifier. The mosfet output power stage is controlled by a 20 Khz PWM (Pulse
Width Modulation) signal that allows it to drive servo motors where high dynamic performance and
precise speed is required.

Notes during the assembly
Caution: during the wiring of the servodrive in the electrical box, make sure that do not enter leading
wires of copper or iron chips through the slits. Before performing the work cover the holes with a
piece of paper tape. Naturally finished work this tape is removed.
1.6 Ventilation
Positioning in the electrical box
Follow the instructions in the positioning of the servodrive in the electrical box.
- The drive is natural convection air flow cooled.
- To ensure the drive cooling and make the installation easier for the operator it must be installed
vertically leaving a free space of at least 20 mm (0,78 inch) on each side of the device.The converter
mustbe mounted verticallyon the electricalbox.In case youwant to mountithorizontally,removethe
cover.
- The electrical box must have suitably filtered air vents.
- Leave the necessary space both above and below the converters.
- Keep the drive from excessive mechanical vibration
