SAFETY

Servodrives present two main types of hazard :

- Electrical hazard

Servoamplifiers may contain non-insulated live AC or DC
components. Users are advised to guard against access to live
parts before installing the equipment.

Even after the electrical panel is de-energized, voltages may be
present for more than a minute, until the power capacitors have
had time to discharge.

Specific features of the installation need to be studied to prevent
any accidental contact with live components :

- Connector lug protection ;

- Correctly fitted protection and earthing features ;

- Workplace insulation
(enclosure insulation humidity, etc.).

General recommendations :

• Check the bonding circuit;

• Lock the electrical cabinets;

• Use standardised equipment.

- Mechanical hazard

Servomotors can accelerate in milliseconds. Moving parts must be
screened off to prevent operators coming into contact with them.
The working procedure must allow the operator to keep well clear
of the danger area.

All assembly and commissioning work must be done by qualified
personnel who are familiar with the safety regulations (e.g. VDE
0105 or accreditation C18510).

1.3.3 Servomotor control functions

1.3.3.1 Presentation

The DIGIVEX Little Drive (DLD) servo-amplifier is a 4-quadrant, transistor control module for
controlling (brushless) synchronous motors with resolvers.

NX, LX, LS, LD spindle drive motors. See separate documentation (PVD3407 and PVD3535).

The customization of the motor - resolver unit and the setting of the servocontrol parameters are
carried out using a PC with DIGIVEX software (PME software, DIGIVEX module), under
Windows.

These parameters are stored in an EEPROM permanent memory.

1.3.3.2 Functions and block diagram

See next page. The diagram shows the main drive functions and the setting parameters.

PVD 3530 GB 01/2005

On the right of the diagram, the motor - resolver - power section.

Parameters can be set for:

⇒ the choice of motor, which dictates the drive rating.
⇒ the general characteristics of the resolver.

The choice of the motor - drive combination determines a number of parameters: current
limitation, I

2

= f(t) protection, standard servo-control parameters.

Ahead of current control.

♦ Second order filter for reducing the effect of high-frequency resonance
♦ External reduction of current limitation

Resolver numerical processing (non parametric) and the encoder emulation function (number of
lines adjustable from 1 to 16384).
Choice of type of regulation: torque or speed.
In speed loop. Parameters can be set for :

⇒ maximum speed for the application (limited by the maximum motor speed).
⇒ scaling (1 V = N rpm).
⇒ choice of corrector type: proportional, proportional and integral, proportional and

double integration.

Predictive actions associated with speed control.

These actions, acting outside the speed loop, directly affect torque. As they are external they
have little effect on loop stability. However, they allow anticipated actions, without waiting for the
speed loop reaction.

The predictive actions (or predictors) are:

Gravity: compensation for vertical masses.

Dry friction: a friction force value is fixed. The corresponding torque set point is applied, its sign
being that of the speed set point.

Viscous friction: compensation for friction forces that are proportional to speed (hydraulic or
electrical system drive).

Acceleration: changes in the speed set point (drift) are monitored and direct action is taken on
the torque set point via a coefficient K, the inertia image.

The analog input speed reference (13 bits + sign), non parametric.

On the left of the block diagram, the set of logic and analog inputs / outputs.

The parameter setting software is used:

for allocating some of these Inputs / Outputs.

for forcing them to a logic status. The inputs are then disconnected from the outside.

PVD 3530 GB 01/2005

1.3.3.3 Forcing logic inputs

The software allows the logic input to be forced to a value. Consequently, via the software, the
SPEED RANGE, CW, CCW, TORQUE inputs are able to:

"disconnect" them from the physical input.
force them by software to 0 or 1.

1.3.3.4 Stimuli / oscilloscope functions

Certain functions integrated in the drive allow the speed set point to be excited: dc voltage,
square (response at one scale), sine.

These stimuli are activated by a PC. Their result, stored in the amplifier, can be seen on the PC
screen by using the oscilloscope function (a maximum of 4 variables can be displayed
simultaneously via the PME DIGIVEX software).

1.3.3.5 Speed ramp function

A ramp function is integrated into the drive unit for versions of software above AP516V07, running
with PME version 4.04 or above. This function is used to create time dependent linear speed
ramps. Parameters can be set in “Servo-control settings” under the “ramp” tab:

- Times t1, t2, t3, and t4 can be programmed from 0 to 1000s.

- Speeds Vp and Vn can be programmed from 0 to 50,000 rpm.

Comment:
Vp and Vn are points on the ramp; they can be defined outside of maximum motor speed.
However, servo-controls will limit the motor speed to the maximum authorized speed.

PVD 3530 GB 01/2005

How the ramp operates:

The ramp input can either be the analog input instruction or the stimuli generator as shown below:

In the event that the input is analog, scaling is carried out by the input instruction product (V) * speed
range for 1V, the speed range for 1 volt can be found in the servo-control dialogue box.

Ramp activation is validated by the information “TORQUE=1” (enable torque activated).
Therefore, the ramp operates as soon as the zero torque information is unlocked and an operating
direction (CW or CCW) selected. When CW or CCW is deactivated, the motor decelerates in
accordance with the pre-set ramp which means that CW or CCW cannot be selected as
mechanical stops.

Important remarks:

- When “TORQUE” is successively deactivated and reactivated, the speed is reduced to
zero prior to following the progression of the ramp.

- The ramp function must be deactivated

when a DLD with digital control is used to carry

out a check on the axis position.

(input instruction – threshold (OUT2) < actual speed < input instruction + threshold (OUT2)

NB

: 48 rpm ≤ threshold (OUT2) ≤ 5252 rpm

1.3.3.7 Brake action

The drive can be declared in the parameters with a brake function.

The 24 V brake supply (terminal block B1) is monitored by the drive.

24 V present: Axis under torque. Removal of limitation of 90% of rated motor current.
24 V absent: Axis at reduced torque with 90% of rated motor current.

The brake engage or release order is in no event given by the drive but by the external control.
The control can monitor the drive outputs indicating zero speed to decide whether or not to apply
the brake.

2. ENERGY DISSIPATION

The energy a module has to dissipate is broken down into:

Energy generated by braking.
Energy from rectifier and power bridge losses.

2.1 Braking Energy Dissipation

2.1.1 Calculating the power to be dissipated in the braking resistor

The permanent and pulse power levels given in the table below are limited by the characteristics
of the "breaking" resistors.
When the application includes intensive cycles or long-duration decelerations, the mean power to
be dissipated by each axis must be calculated.

P in Watts =

J2N

9.55

2

⎛
⎝

⎜

⎞
⎠

⎟

.f

J : Moment of inertia of the servomotor and the related load in kgm².
N : Angular speed of motor shaft at start of braking, in rpm.

f : repeat frequency of braking cycles in s

-1

.

This formula is for the least favourable case. For a mechanism with substantial friction or with low
reverse output, the power to be dissipated may be greatly reduced.

.

The power to be dissipated by the axis must not exceed the permanent power admissible by the
resistor. Duration and repetition must not exceed the ratings in table § 2.1.3.

2.1.2 Braking energy dissipation

Dissipation of breaking energy is carried out through a resistor (or 2 resistors depending on the
calibre) situated in the module.

Definitions

Maximum power: Maximum power drawn, resistance connecting is carried out at 360V, hence,
the power drawn has a maximum resistance value equal to 360.

Pulse power: maximum power dissipated by the resistor, this power can only be drawn for a
short time and in compliance with a certain cycle.

Permanent power (to 25°C) : mean power that can be dissipated on a permanent basis by the
resistor.

2.2 DLD paralleling

The braking capacity of applications requiring the use of several DLD, placed in the same
electrical control cabinet, can be increased

(1) (2)

. It is only a question of linking the DC buses from
all the DLD using the B4 connector provided for this purpose. The operation quite simply
comprises of combining the braking capacities of all the appliances.

(1) If cycle simultaneity does not exist between the axes:

There is no synchronization between the braking axes

(2) It is possible to use the axes’ synchronism according to the following cycles:

Braking of one axis whilst another axis is accelerating.
(the braking energy is used to accelerate the other axis).

Connections:

Connector Contact Function

B4 1 DC+
B4 2 DC-

Connections are carried out from DC+ to DC+, DC- to DC-.

Maximum number of parallel axes: 6.

Connecting cover cables section: 1mm² minimum (cable reference: UL 1015 AWG16)

Maximum length of connection: 300mm of connecting cable (connection to be kept as short as
possible).

Every axis must remain connected to the electric mains supply (it is absolutely forbidden to
connect 1 axis to the mains and then use the DC bus link as a power supply for the axes
connected via this connection).

Follow the electrical connection plans on pages 25 and 26, especially with regard to all axis and
line fuses.

The axes linked together by the DC buses must be connected to the same electric mains supply.

A clear 10mm must be spaced between each axis.

Plan of dimensions: see page 19

Electrical connection plans: see pages 25 and 26.

4. ELECTRICAL CONNECTIONS

4.1 General Wiring Requirements

4.1.1 Appliance handling

Please refer to the safety instructions given at the beginning of this booklet. It is strongly
recommended that personnel wait for the 7-segment display, situated on the front panel, to go off
before undertaking any intervention of the servoamplifier or servomotor.

4.1.2 Electromagnetic compatibility

EARTHING

Comply with all local safety regulations concerning earthing.
Utilize a metal surface as an earth reference plane (e.g. cabinet wall or assembly grid). This
conducting surface is termed the potential reference plate. All the equipment of an electrical
drive system is connected up to this potential reference plate by a low impedance (or short
distance) link. Ensure the connections provide good electrical conduction by scraping off any
surface paint and using fan washers. The drive will then be earthed via a low impedance link
between the potential reference plate and the earth screw at the back of the DIGIVEX Little
Drive. If this link exceeds 30 cm, a flat braid should be used instead of a conventional lead.

CONNECTIONS

Do not run low-level cables (resolver, inputs/outputs, NC or PC links) alongside what are termed
power cables (power supply or motor). Do not run the power supply cable and the motor cables
alongside one another otherwise mains filter attenuation will be lost. These cables should be
spaced at least 10 cm apart and should never cross, or only at right-angles.
Except for the resolver signals, all low-level signals will be shielded with the shielding connected
at both ends. At the DIGIVEX Little Drive end, the shielding is made continuous by the Sub-D
connector mechanism.
The motor cables are limited to the minimum functional length. The yellow and green motor
cable lead must be connected to the box or front panel terminal block with the shortest possible
link.
This usually means shielded motor cable is not required. Chokes may also be inserted into the
motor phase leads.

OTHER MEASURES

Self-inducting components must be protected against interference: brakes, contactor or relay
coils, fans, electro-magnets, etc.

4.1.3 DIGIVEX Little Drive Sub-D connectors

In order to ensure the system is free from disturbances, it is essential for the rack to be properly
connected to the earth plane of the electrical cabinet and for the covers of the Sub-D connectors
to be EMI/RFI shielded (metal with shielding braid connection).
Make sure the Sub-D connectors and their covers are properly connected (lock screws fully
tight).
