The expansion module monitors standstill, speed and direction of rota­tion in accordance with EN ISO 13849-1 up to PL e and EN IEC 62061
up to SIL CL 3.

The expansion module may only be connected to a base unit from the
configurable control system PNOZmulti (please refer to the document
"PNOZmulti System Expansion" for details of the base units that can be
connected)

The configurable control system PNOZmulti is used for the safety-relat­ed interruption of safety circuits and is designed for use in:

 E-STOP equipment
 Safety circuits in accordance with VDE 0113 Part 1 and EN 60204-1

WARNING!

Users must take appropriate measures to detect or exclude
errors (e.g. slippage or broken shearpin) which cause the fre­quency of the encoder signal to no longer be proportional to the
monitored speed.
Appropriate measures are:

 Using the monitored encoder to also control the drive
 Mechanical solutions

WARNING!

Encoder errors are detected and signalled via a diagnostic bit.
This does does not bring the relevant axis to a safe condition.
To maintain safety (Category 3), the diagnostic bit (diagnostic bit

10) in the user program must be evaluated in such a way that a
shutdown occurs if the axis is in operation (see examples in
Chapter 9).

The speed monitor can independently monitor two axes for standstill,
speed and direction of rotation. The speed monitor signals the status of
the monitored values to the base unit. Depending on the implemented
safety circuit, the values may be transferred from the base unit to a relay
output on the safety system, for example. Incremental encoders may be
used to record the values.

Montage_multi_Bild_BA

 The control system should be installed in a control cabinet with a pro-

tection type of at least IP54. Fit the control system to a horizontal
mounting rail. The venting slots must face upward and downward.
Other mounting positions could destroy the control system.

 Use the notches on the rear of the unit to attach it to a mounting rail.

Connect the control system to the mounting rail in an upright position,
so that the earthing springs on the control system are pressed on to
the mounting rail.

 The ambient temperature of the PNOZmulti units in the control cabi-

net must not exceed the figure stated in the technical details, other­wise air conditioning will be required.

 To comply with EMC requirements, the mounting rail must have a low

impedance connection to the control cabinet housing.

CAUTION!

Damage due to electrostatic discharge!
Electrostatic discharge can damage components. Ensure
against discharge before touching the product, e.g. by touching
an earthed, conductive surface or by wearing an earthed arm­band.

The wiring is defined in the circuit diagram of the PNOZmulti Configura­tor.

Details of the input type, axis type and reset mode, plus the values for
standstill, speed monitoring and direction of rotation are also defined in
the PNOZmulti Configurator.

Please note:

 Information given in the "Technical details" must be followed.

Verdrahtung

 Use copper wire that can withstand 75 °C.

CAUTION!

The configurable switch-off delay when overspeed is reached
increases the reaction time of the system comprising base unit
and speed monitor by the stated value (see technical details).
This must not delay the transfer to a safe condition by more than
the permitted time. The configuration of the switch-off delay
must be considered in the risk assessment as regards hazards,
reaction time and safety distance.

6.2.1 Connecting the incremental encoder

Connecting the incremental encoder6-Drehzahlwaechter_Betriebsb_Inkremen

Follow the instructions below when connecting the incremental encod­er:

 The incremental encoder can be connected via an adapter (e.g. PNOZ

msi4p) or can be connected directly to the speed monitor.

 The incremental encoder on connector X12 monitors axis 1; the incre-

mental encoder on connector X22 monitors axis 2.

 Only use shielded cables for all connections
 Always connect 0 V on the incremental encoder and speed monitor.
 Position the terminating resistors on the signal lines as close as pos-

sible to the input on the speed monitor.

 The adapter (e.g. PNOZ msi6p) is connected between the incremental

encoder and the drive. The output on the adapter is connected to the
RJ-45 female connector on the speed monitor.

 The adapter also can be used without connecting to a drive. The sig-

nal lines can then be terminated directly at the adapter with Z

 If the signal lines in the drive are already terminated with Z

 The signals relevant for the speed monitor are utilised in parallel by

the adapter. The information stated in section 6.2.2.1 and in the
adapter operating manual must be observed when connecting the
supply voltage.

 Supply 5 VDC to incremental encoder only.

copies the configuration from the chip card.

The LEDs "POWER","DIAG", "FAULT", "IFAULT" and "OFAULT" light up

Evaluation of bit: "Unfeasible or single-channel signal from the
incremental encoder", without position control

Diagnosticbit 10: "Unfeasible or single-channel signal from the incre­mental encoder" must be evaluated in the user program during opera­tion in such a way that a set bit leads to a safety-related error reaction
(shutdown).

9.1.1 Example 1

Example 19-Applikationsbeispiel_ohne_Lageregelung_1_PNOZms3_sofort_absch_BA

Immediate shutdown as soon as diagnostic bit 10 is set.
The bit is evaluated as follows:

The connection point "Input Device OK" must be incorporated into the
application and evaluated in such a way that a shutdown occurs if the
connection point "Input Device OK"= 0.

A set diagnostic bit 10 can be tolerated for a maximum of 4 hours (oc­currence of second error). If no feasible signals above standstill frequen­cy are measured within this time, a shutdown will occur.
In this case, the bit will be evaluated as follows:

Evaluation of bit: "Unfeasible or single-channel signal from the
incremental encoder", with position control

Diagnostic bit 10: "Unfeasible or single-channel signal from the incre­mental encoder" may be set during position control as a result of jitter
on the encoder.

The set bit can be tolerated, i.e. evaluated in the user program in such a
way that a shutdown will not occur if the following conditions are met:

 An additional position control signal must be provided from an exter-

nal control system (e.g. PLC) and

 The signal must have the following status conditions:

– Position control: Signal status = 1
– Operation: Signal status = 0

During operation, diagnostic bit 10 must be evaluated in the user pro­gram in such a way that a set bit leads to a safety-related error reaction
(shutdown).

9.2 Example with position control

Depending on the operating mode, evaluation of diagnostic bit 10 can
be implemented in the user program as follows

9-4

An additional "Position Control" signal is incorporated. This signal indi­cates whether the relevant axis is in position control (signal status = 1)
or in operation (signal status = 0).

The time element with configured switch-off delay operates as a start­up suppressor, as the bit: "Unfeasible or single-channel signal from the
incremental encoder" may still be present for 2 s after leaving standstill.

The connection point "Input Device OK" must be incorporated into the
application and evaluated in such a way that a shutdown occurs if the
connection point "Input Device OK"= 0.
