1.1 Description
OPERATIVE MODES
SPEED CONTROL It is speed piloting utilising a digital reference or an
analogue reference (differential or common mode). standard
TORQUE CONTROL
It is torque piloting utilising a digital reference or an
analogue reference. This function allows you to control the
current from the drive.
standard
POSITION CONTROL
The positioner can be managed via hardware (by using the
digital inputs) or via RS232 (by using the Axor's Speeder
One interface or another ModBus Master). It supports 32
programmable position proles; a single task or a sequence
of tasks are permitted.
The Homing Procedure is implemented. It uses the signal
coming from the homing sensor and eventually the zero
signal of the encoder.
standard
ELECTRICAL AXIS
(GEARING)
It is possible to pilot the drive with the quadrature signals
of an emulated encoder from a Master drive or with the
quadrature signals of an incremental encoder from a Master
motor (Electrical Axis or Gearing).

PULSE/DIRECTION
It is possible to connect the drive to a stepper-motor
controller, piloting it with the +/-Pulse and +/-Dir signals
(Pulse/Dir Mode).
optional
MULTIDROP RS232
It can work in Multidrop, where the rst drive, connected
via RS232 to the Master PC, is piloted with ModBus
communication, while the other drives are piloted with the
duplication of commands using the CanBus interface.

2.1 General Advices
During the transport of the drive respect the following indications:
• the transport must be made by qualied personnel;
• avoid shocks;
• the temperature range must be between -20°C and +55°C;
• the max. humidity must be 95% (without condensation);
• The converters contains elements which are sensitive to electrostatic discharges. These elements
can be damaged by careless manipulation.
Discharge static electricity from your body before touching the converter.
Avoid contact with material that insulates well (synthetic bres, lms of plastic material and so
forth).
• we suggest to check the motor condition at its arrival to survey eventual damages.
Transport
The unused drives must be storage in an environment having the following characteristics:
• temperature from -20°C to +55°C;
• max. relative humidity 95% (without condensation);
• max. time with the drive powered off (without supply connections):
 drive having a power supply ≥ 220VAC 1 year
 drive having a power supply ≤ 145VAC (200VDC) 2 years
After this time, before enable the drive, it is necessary activate the capacitors following this procedure:
remove all electrical connections, then supply the input terminals of the supply with the main voltage
(three phase or single phase) for 30 minutes.
In details:
- for the drive having a power supply equal to 380VAC: power it by using a single phase (or three
phase) supply equal to 220VAC;
- for the drive having a power supply equal to 220VAC: power it by using a single phase (or three
phase) supply equal to 110÷130VAC.
In order to avoid this procedure, we suggest to power on the drive with its rated voltage for 30 minutes,
before the max. time is reached.
Storage
The drives does not need maintenance.
Otherwise:
• if the casing is dirty: clean it with isopropanol or similar;
• if the drive is dirty: the cleaning is reserved to the producer;
• if the fans are dirty: clean them by using a dry brush.
Maintenance
The disposal should be carried out by a certied company.

2.1 General Advices
• This manual is exclusively addressed to technical personnel with the following require-
ments:
- Technician with knowledge on movimentation of elements sensitive to electrostatic
discharges (for the transport).
- Technician with appropriate technical training and with vast knowledge on electrotech-
nics/drive technical eld (for the installation and operation of servodrives).
Using the drive incorrectly can injure people or damage things. Fully respect the technical
data and indications on connection conditions.
• As well as the points described in this manual, current regulations regarding safety and accident
prevention must be followed in order to prevent accidents and residual risks.
• The user must analyse possible machine risks and take the necessary measures to avoid injuries to
people and damage to things because of unpredictable movements.
• The converters contains elements which are sensitive to electrostatic discharges. These elements can
be damaged by careless manipulation.
Discharge static electricity from your body before touching the converter.
Avoid contact with material that insulates well (synthetic bres, lms of plastic material and so
forth).
• During operation, the converter surface can become hot. Protect the user from accidental contact
and keep the indicated distances from all objects.
• Never loosen electrical connections while the servoampliers are being powered.
The appropriate terminals of the drive must always be connected to earth as instructed in this manual.
After having disconnected the converters from the supply current, always wait at least 5 minutes before
touching the powered components (e.g. contacts) or loosening connections.
• Switch off the converter and wait at least 5 minutes before opening it. Remove the fuses or switch
off the main switch before removing the drive. When opening, place the converter on a surface that
does not belong to the electrical panel.
• The residual charges in the capacitors can remain at a dangerous level for up to 5 minutes after dis-
connection from the mains. Measure the voltage at the intermediate circuit (+AT/-AT) and wait until
it is below 15V.
• The command and power connections can still hold current even when the motor has stopped.
•The MiniMagnumTM is equipped with electronic protections that deactivate it in case of irregularities.
The motor, as a result, is not controlled and can stop or go into neutral (for a time determined by the
type of system).
•During installation, avoid letting any residue with metallic components fall inside the drive.
Security standard

16 AXOR Industries Service Manual MiniMagnumTM ver.1 rev.05/'15
•Protect the converter from excessive mechanical vibrations in the electrical box.
•Check that the main supply and the nominal current are coherent with the rating of the drive. Be
sure that the voltage between the connectors L1-L2-L3 is not greater than 10% of the nominal values.
An excessively high voltage causes the breakdown of the load circuitry and of the drive.
•The MiniMagnumTM is equipped with an integrated EMI anti-disturbance lter at the 3-phase power
supply input and with another EMI anti-disturbance lter at the auxiliary +24V power supply input.
Being implicit to lter operation the deviation towards earth or mass of the undesired frequencies,
ensure that these devices can produce leakage currents towards earth, which are measurable in mil-
liAmpers. Please remember that "leakage currents" must be considered when settings differential
devices in order to avoid useless interventions.
For safety reasons connect the prepared terminal to earth before powering the drive. Incorrect con-
nections make lter operation unreliable.
2.1 General Advices

17
AXOR Industries Service Manual MiniMagnumTM ver.1 rev.05/'15
The MiniMagnumTM is made to be xed vertically to the bottom of the electrical box in order to
guarantee reliable cooling, respecting the following distances:
2.2 Positioning
Note: Arrange the power components (converters, main's lters, resistors, terminals, ... ) in bins of
the electrical panel different from those reserved to the command or control systems (PLC, PC, CNC,
regulators, ...). This improves the level of immunity to interference of the system.

Pollution level
LEVEL 2 (Norm EN60204/EN50178)
The drives are designed to be utilized in an electrical
box protected against the inltration of polluting agents
such as water, oil, conductive dust and others.
Notes:
• The electrical box must have suitably ltered air vents.
Leave the necessary space both above and below the converters.
• Periodically check drive case and fans for excess dust or dirt, that could interfere with the correct
dissipation of the drive.
