Colibri
Compact drives
precise – flexible – efficient

Compact format – innovative solutions – future-proof technology
These have been the driving factors for GUNDA Electronic GmbH since its
foundation in 1995 – the year in which the company brought the first compact
drive to the global market. Since then GUNDA Electronic has been working
in the field of automation solutions with stepper motor technology to develop
compact components with simple operation, which facilitate economical
and energy-efficient solutions for diverse and individual applications.
All products are developed at GUNDA Electronic by a qualified and experienced
team and are produced in Germany in accordance with high quality benchmarks.
Economical alternative to solutions with air
GUNDA drive systems are the alternative to pneumatic axes.
The advantages: Better drive behaviour, more precise positioning, greater
flexibility, easy and individual configuration, lower operating costs.
Our products
Colibri: The compact drive
Faster, more precise change of position with optimised energy consumption
The Colibri drive constitutes the basis of our products - controller and motor in a compact
unit: Position control with program memory, power output stage, diverse inputs and outputs,
various bus connections and an integrated encoder.
Colibri-C: The controllers
The heart of the system by itself
For use in a switch cabinet or directly adjacent to the motor with varying scopes of functionality,
from simple basic control right through to bus variants.
Colibri-L: The electrical linear units
The Colibri drive paired with linear movement
The linear units are available as electrical spindle axes, toothed belt axes, lifting cylinders,
lifting cylinders with guide unit or as short lifting units, each complete with attached motor
and controller.
Colibri-G: The gripper
Small, intelligent and all the requisite functions aboard
The electrical gripper with extremely simple operation and infinitely adjustable gripping
force.
We keep a comprehensive range of accessories in stock for project planning, assembly and commissioning.

Colibri – the optimum solution for decentralised drive tasks
compact and safe
Low installation volumes and minimal wiring requirements enable installation
even where spatial conditions are tight; the robust EMC-protected housing
is fully potted and ensures safe operation even under harsh ambient conditions.
• precise
• flexible
• efficient
quiet and low-resonance
The dynamic switching of the step resolution ensures quiet, low-resonance
running, particularly at low speeds.
reliable and precise
The compact format of Colibri drives guarantees low-maintenance operation
over a lengthy service life; the perfect interplay between electronics
and mechanics as well as the integrated position monitoring ensure precise
positioning and controlled operation of the stepper motor.
simple and economical
Straightforward commissioning ensures an effective and economical drive
solution.

Sophisticated precision – the Colibri drive
Our "intelligent axes" – the Colibri drives – are used for a wide range of applications, where cost or space savings
demand decentralised drive solutions. A dynamic switching of the step solution ensures quiet and low-resonance running
behaviour.
The compact devices comprise a stepper motor and an electronic unit – compact within a single housing.
The controller is fully potted and therefore offers:
A high protection class, IP67 (without motor), optimum temperature control and comprehensive safeguarding
against vibrations

Customer-specific
applications:
These are easily realised due to the operating system's integrated "download function".
Dimensions:
The dimensions of the compact devices are dependent on the motors used (refer to datasheets).
Operating modes
Variants
Operating mode
Set selection: Sets stored in the controller (max. 31) can be preselected and started via 5 binary encoded inputs in any order.
Set sequence: A program sequence stored in the controller is processed on a set-by-set basis with the input "Start".
Digital I/O
Print mark control: In drive mode the positioning is determined by means of a print mark. The drive runs until the "Print
mark" input comes and then ramps down.
Flank selection: A modification for the versions set selection and set sequence is possible in that the positioning can
be triggered with either the positive or the negative starting flank.
Clock/direction
Profibus DP
CANopen
RS485
The compact unit is able to process clock and direction signals directly from a superordinate control. The following
operating modes can be set: Full step operation, half step operation, quarter step operation, eighth step operation.
