Safety and application notes

for drive controllers

(according to: Low Voltage Directive 73/23/EWG)

1. General

During operation, drive controllers may have, according to their type of
protection, live, bare, in some cases also movable or rotating parts as well as
hot surfaces.

Unauthorized removal of the required cover, inappropriate use, incorrect
installation or operation, creates the risk of severe personal injury or damage to
material assets.

Further information can be obtained from the documentation.

All operations concerning transport, installation, and commissioning as well as
maintenance must be carried out by qualified, skilled personnel (IEC 364
and CENELEC HD 384 or DIN VDE 0100 and IEC report 664 or DIN VDE 0110
and national regulations for the prevention of accidents must be observed).

Qualified skilled personnel according to this basic safety information are
persons who are familiar with the erection, assembly, commissiong, and
operation of the product and who have the qualifications necessary for their
occupation.

2. Application as directed

Drive controllers are components which are designed for installation into
electrical systems or machinery.

When installing into machines, commissioning of the drive controllers (i.e. the
starting of operation as directed) is prohibited until it is proven that the machine
corresponds to the regulations of the EC directive 89/392/EWG (Machinery
Directive); EN 60204 must be observed.

Commissioning (i.e. starting of operation as directed) is only allowed when
there is compliance with the EMC Directive (89/336/EWG).

The drive controllers meet the requirements of the Low Voltage Directive
73/23/EWG. The harmonized standards of the prEN 50178/ DIN VDE 0160
series together with EN 60439-1/DIN VDE 0660 part 500 and EN 60146/DIN
VDE 0558 are applicable to drive controllers.

The technical data and information about the connection conditions must be
obtained from the nameplate and must be observed in all cases.

3. Transport, storage

Notes for transport, storage and appropriate handling must be observed.

Climatic conditions must be observed according to prEN 50178.

3

L

4. Erection

The devices must erected and cooled according to the regulations of the
corresponding documentation.

The drive controllers must be protected from inappropriate loads. Particularly
during transport and handling, components must not be bent and/or insulation
distances must not be modified. Touching of electronic components and
contacts must be avoided.

Drive controllers contain electrostatically sensitive components which can
easily be damaged by inappropriate handling. Electrical components must not
be damaged or destroyed mechanically (health risks are possible!).

5. Electrical connection

When working on live drive controllers the valid national regulations for the
prevention of accidents (e.g. VBG 4) must be observed.

The electrical installation must be carried out according to the appropriate
regulations (e.g. cable cross-sections, fuses, PE connection). More detained
information is included in the documentation.

Notes concerning the installation in compliance with EMC - like screening,
grounding, arrangement of filters and laying of cables - are included in the
documentation of the drive controllers. These notes must also be observed in
all cases for drive controllers with the CE mark. The compliance with the
required limit values demanded by the EMC legislation is the responsibility of
the manufacturer of the system or machine.

6. Operation

Systems where drive controllers are installed must be equipped, if necessary,
with additional monitoring and protective devices according to the valid safety
regulations, e.g. law on technical tools, regulations for the prevention of
accidents, etc. Modifications of the drive controllers and the operating software
are prohibited.
After disconnecting the drive controllers from the supply voltage live parts of the
controller and power connections must not be touched immediately because of
possibly charged capacitors. For this, observe the corresponding labels on the
drive controllers.

During operation, all covers and doors must be closed.

7. Maintenance and servicing

The manufacturer´s documentation must be observed.

This safety information must be preserved!
The product specific safety and application notes in these operating
instructions must also be observed!

2.3 Scope of supply

The scope of supply includes:

• the controller 53x_E

• the operating instructions

• the set-value potentiometer 10 kΩ

• plug-in terminals

2.4 Application as directed

•

The controllers of the types 53x are electrical equipment for installation into
control cabinets of electrical systems or machinery.

• The controllers of the types 53x are designed as components for the control

of speed-variable drives with separately-excited DC motors or for the
assembly with other components to form a machine or system.

• Drive systems with drive controllers 53x which are installed according to the

definition of a CE-typical drive system (see chapter 4.2.2), correspond to the
EC EMC Directive and the standards mentioned below.
CE-typical drive systems are

- suitable for the operation on public and non-public mains and

- provided for industrial applications.

• Because of the ground potential reference of the RFI filters, the CE-typical

drive system which is described is not suitable for the connection to IT mains
(mains without ground potential reference).

• The drive controllers are not domestic appliances, but they are designed for

drive systems for commercial use.

• The controllers of the types 53x themselves are not machines according to

the EC Machinery Directive. The final function is only determined when
integrated into the machine construction of the user.

• The user must consider measures in his machine construction which limit the

consequences in case of malfunction or failure of the drive controller
(increase of the motor speed or sudden motor stop) so that hazards for
persons or material assets cannot be caused, such as:

− further independent equipment for the monitoring of safety-relevant
variables (speed, travel, end positions, etc.)

− electrical or non-electrical protective equipment (latching or mechanical
blocking)

− measures covering the complete system

4 Installation

4.1 Installation

The chassis-type controller is to be installed in a vertical position, with the
terminals at the bottom, to ensure sufficient cooling and air circulation. The
ambient temperature mut not exceed +45°C.

Unwanted voltages fed back from the controllers to the supply mains are
reduced by the connection of mains chokes and RFI filters. The components
allocated to type 53x are listed in chapter 3 "Accessories".

4.2 Connection

•

The controllers contain electrostatically sensitive components. Prior to
assembly and servicing the personnel must be free of electrostatic charges.
Discharging is possible by touching the PE fixing scew or another grounded
metal part in the control cabinet.

• If you use residual current devices:

− The controllers have an internal mains rectifier. After a short-circuit to

frame a DC fault current may prevent the tripping of the residual current
device. Therefore, take additional measures like zeroing or use universal
current e.l.c.b.

− Observe for the dimensioning of the release current of e.l.c.b. that
capacitive compensating currents of the cable screens and RFI filters
occuring during normal operation may cause false tripping.

− Note for the use of universal e.l.c.b.:
The preliminary standard prEN50178 (in the past VDE0160) about the use
of universal e.l.c.b. has been decided by the German committee K226.
The final decision about the use in compliance with the standard is made
by the CENELEC/CS (European Committee for Electrotechnical
Standardization) in Brussels. Further information on the use of universal
current e.l.c.b. can be obtained from the supplier.

14

L

• The plug connector is suitable for the connection of solid wire or single or

multi-strand conductors of cross-sections between 0.14 and 2.5 mm². The
length of the free wire should be between 8 and 9 mm. It is not necessary to
use ferrules.

1

2

3

1

Before removing the protective cover, switch-off the controller and remove the
connectors.

Warning
All controller terminals carry mains potential. It is therefore necessary that
all input and output signals required for the control of the controller are,
electrically, safely separated by measures outside the controller and have
another protection against direct contact (double basic insulation).

When using the supplied set-value potentiometer the mechanical fixing
must have an additional PE connection and the connections must be
insulated and covered.

Prior to commissioning make sure that there is no earth fault in the connecting
cables. The protective conductor must only be connected to the PE connection
(6.3-mm spade connector). PE or ground connections to any other terminals
cause a controller failure.
Screen motor cables A, B, I and K as well as the control cables. The screen
must be connected at both ends to the central PE connection. The control
cables must not be longer than 10 m. Check the voltage rating of the screened
cable.

To ensure that the screening is effective, it should not be opened or interrupted.
It should also be laid as close as possible at the cable ends. Connect the
screening of the motor cables to PE in the motor terminal box.

15

l

If the cable between RFI filter and controller is longer than 200 mm, use
screened mains cables. The ground chassis connection should have as low a
resistance and as large a surface as possible.

Type 53x can be used for operation with armature voltage or tacho feedback
(see chapter 4.5 "Connecting diagram").
In case of armature voltage control with "I x R compensation" insert a jumper
between terminal 2 and terminal 4.

Caution!
At terminals 2/4 and 3/4 only the feedback system used must be
connected.

For master voltage operation remove the set-value potentiometer and apply the
master voltage across terminal 7 (-) and terminal 8 (+).

Caution!
The master voltage must be free of mains and ground potential. Several
controllers can only be operated from a master voltage when they are
electrically isolated.

4.2.1 Installation corresponding to EMC

•

Controllers cannot be operated on their own. The EMC of controllers on their
own cannot be tested. Only the integration of the controllers into a drive
system allows a test whether the objectives of the EC EMC Directive are met
and whether the device are in compliance with the law about the
electromagnetic compatibility of equipment.

• Lenze has done conformity tests with the controllers of the types 53x in

certain, defined drive systems. These tested drive systems are called "CE­typical drive system" in the following.

• Therefore, the user of the controller has the choice,

− either to determine the system components and their integration into a

drive system himself and to determine the conformity under his own
responsibility

− or to install the drive system according to the CE-typical drive system as
tested by the manufacturer of the controller and declared to be in
compliance.

• If you observe the following measures you can assume that EMC problems

caused by the drive system will not arise during the operation of the machine
and the EMC Directive and the EMC law are satisfied.

• For any other installation, e.g.

− use of unscreened cables,

− use of collective RFI filters instead of the allocated RFI filters,

− omission of mains chokes

the machine or system must be tested whether it is compliance with the EC
EMC Directive and the EMC limit values are considered.

• The compliance with the EMC Directive in the machine application is

the responsibility of the user.

Installation of the CE typical drive system

The electromagnetic compatibility of a drive system depends on the type and
accuracy of the installation.
Take special care with

− filters

− screening

− grounding

Filters

• Only use the RFI filters and mains chokes allocated to the controllers (see

chapter 3 "Accessories").

− RFI filters reduce non-permissible high-frequency interferences to a

permissible value.

− Mains chokes reduce low-frequency interference which depends primarily

on the motor cables and their length.
For motor cables which are longer than 50 m additional measures are
required.

Screening

• Screen all cables from and to the controller.

• Make sure that motor cables are separated from signal and mains cables

when laying the cables.

• Avoid a common terminal board for mains input and motor output.

• The cables must be laid as close as possible to the reference potential.

Dangling cables are like antennas.

18

L

Grounding

• Ground all conductive metal components (controllers, RFI filters, mains

chokes) by suitable cables from a central grounding point
(PE bar).

• Observe the minimum cross-sections prescribed in the safety information.

However, for EMC the surface of the contact is important and not the cross­section.

Assembly

• Make a contact from controller, RFI filter, and mains chokes to the grounded

mounting plate with as large a surface as possible. Zinc-coated mounting
plates allow long-lasting contacts. For painted plates the paint of the
mounting plates must be removed in all cases.

• If you use several mounting plates:

− Make a conductive connection of the mounting plates with as large a

surface as possible (e.g. using copper bands).

• Connect the screen of the armature and field cable to the mounting plate with

as large a surface as possible:

− Recommendation: Make the large-surface connection of the screens to the

mounting plate with earthing clamps on bare metal mounting surfaces.

• If there are contactors, motor protection switches, or terminals in the

armature cable:

− Contact of the screens of the connected cables to each other and to the

mounting plate with as large a surface as possible.

• In the terminal box, connect the screen of the motor to PE:

− Metal cable glands at the motor terminal box ensure a large-surface

connection of the screen to the motor housing.

• If the total length of the mains cable between RFI filter and mains chokes and

controller exceeds 200 mm:

− Screen mains cables

− Connect the screen of the mains cables to the mounting plate with as large

a surface as possible.

• Connect the screen of the control cables to the mounting plate with as large a

surface as possible.

4.3 Connecting voltage

As a standard, the controller is factory-set for the operation on a mains voltage
from 190 to 265 V ±0 %. For a mains voltage from 100 to 132 V ±0 % replace
jumper "BR1" with "BR2".

Caution!
This modification must only be carried out by qualified skilled personnel
when no voltage is applied. After replacing the jumpers the protective
cover must be reassembled.

4.4 Replacing the fuses

The fuses protect the controller from non-permissible operating conditions.
After the operation of such a protective function, the controller and the system
must be checked for further faults before replacing the fuses.

For the replacement of the fuses remove the protective cover and disconnect
the connectors.

Caution!
Removal of the protective cover and the replacement of the fuses must
only be carried out by qualified skilled personnel when no voltage is
applied.

Defective fuses must only be replaced by the prescribed type (see chapter 2.1
"Controller-specific data").

The protective cover must be attached again after the fuses are replaced.

5 Setting

Turn trimmers "I x R", "n

max

", "n

min

", "Ti" and set-value potentiometer fully

counterclockwise. Trimmer "I

max

" is factory set to rated controller current.

The current range selector for type 534 is factory set to 8 A.

5.1 Selection of the current range for type 534

The current range of type 534 can be set to 12 A by switching off the controller
and moving selector S1 from position 8 A to position 12 A.

Caution!
The current range must only be set by qualified skilled personnel when no
voltage is applied.

5.2 Setting the current limit

Setting the current limit is only required if the maximum output current must be
reduced.

• Turn trimmer "I

max

" fully counterclockwise and "n

min

" fully clockwise.

• Connect a moving coil ammeter into the armature circuit to measure the

current.

• Disconnect the field or stall the motor

(observe the current capacity of the motor during standstill!).

• For armature voltage control, remove jumper between terminals 2 and 4.

• Connect mains, close switch "RFR". Turn "I

max

" clockwise to set the

armature current.

• To calculate the value to be set, divide the rated armature current (see

nameplate) by the form factor (I

AN

/ FF).

The permissible rated controller current must not be exceeded.

• Then disconnect the mains, turn "n

min

" fully counterclockwise, connect the
field and for armature voltage control, reconnect the jumper between
terminals 2 and 4.

5.3 Speed setting

•

For armature voltage control with "I x R compensation" insert jumper
between terminals 2 and 4 as shown in the connecting diagram.

• For speed control with tacho feedback remove jumper between terminals

2 and 4. Connect the tachogenerator (see connecting diagram).
For rated tacho voltages > 40 V the setting range of the "n

max

" trimmer can
be improved by removing jumper "BR3" (see chapter 4.5 "Connecting
diagram" and chapter 2.2 "Dimensions").

Caution!
The jumper "BR3" must only be removed by qualified skilled personnel
when no voltage is applied.

In case of uncontrolled acceleration of the motor during speed setting,
immediately open switch "RFR". In this case, either the tachogenerator
feedback is missing or has incorrect polarity.

26

L

After checking and correcting the wiring, commissioning can be started again.

• Switch on the mains and close switch "RFR". Turn the set-value

potentiometer to maximum or set the master voltage to V

LN

= 10 V.

Turn trimmer "n

max

" clockwise until the desired maximum motor speed is

achieved.

• Turn set-value potentiometer fully counterclockwise or set master voltge to 0

V.Turn trimmer "n

min

" clockwise until the desired minimum motor speed is

achieved.

• If the minimum speed is to be zero, turn trimmer "n

min

" counterclockwise
until the motor has just stopped running in order to avoid dead movement of
the set-value potentiometer in the low speed range.
Check the setting of the maximum speed because n

min

and n

max

influence

on each other.

• For armature voltage control with "I x R compensation" the motor speed

loss under load is compensated by turning trimmer
"I x R" clockwise.
Set trimmer "I x R" at low speed until the minimum speed change between
idle running and rated load is achieved. Then, check the setting at higher
speed and the maximum speed setting.

6 Operating modes

6.1 Switching operation

6.1.1 Controller enable

If switch "RFR" is closed, the controller is enabled.
If the switch "controller enable" (RFR) is open, the firing pulses are blocked and
the controller is reset.

RFR

16 17

Note:

Only use low-current contacts for the switching of signal cables
(20 V / 1 mA)

6.1.2 Controller inhibit

The function "RSP", i.e.g the inhibiting of the controller with a normally-open
contact is possible using the following connection.
When "RSP" (controller inhibit) is closed, the firing pulses are blocked and the
controller is reset.

6.2 Electrodynamic braking

If the field is excited, the induced armature current is used for braking the
motor. Before connecting the brake resistor, the controller is inhibited. The
timer relay must be set such that the braking contactor only opens after the
motor has stopped.

The size of the brake resistor depends on the braking energy of the drive and
the number of brakings. The braking current should not be more than twice the
rated armature current and should not exceed the maximum starting current.

To limit the switching voltage peaks, a zinc oxide varistor (RU) must be
connected in parallel to the controller output.

For long motor cables (> 50 m) or motors which are connected in parallel, it
may be necessary to use an interference suppression module (see chapter 3
"Accessories")

6.3 Reversing

Reversing is obtained by changing the armature polarity. The motor is
electrodynamically braked to standstill. The braking time must be set at the
timer relay such that the motor is safely at standstill before the armature is
reversed (for dimensioning of the brake resistor see chapter 6.2
"Electrodynamic braking").
