Introduction
Maximum number of
TSX CFY • 1 modules per station
Step-by-step axis command modules can be installed in any slot of a TSX RKY•• rack. The rack power supply must be chosen according to the number of modules installed.
l l
Each step-by-step command module supports:
1 application-specific channel for TSX CFY 11 module,
2 application-specific channels for TSX CFY 21 module.
Since the maximum number of application-specific channels managed by a PLC station depends of the type of processor installed, the maximum number of l l
TSX CFY •1 modules in a PLC station will therefore depend on: the type of processor installed, the number of application-specific channels already used other than step-by-step command application-specific channels.
You should therefore make a global report at PLC station level to find out the number of application-specific channels already in use and thus define the number of
TSX CFY •1 modules which can be used.
Reminder of number of application-specific channels managed by each type of processor:

Installation procedure
General The module can be installed or removed without cutting the rack power supply, to ensure that a device is available.
CAUTION
Connection and disconnection of connectors
It is not recommended that you connect or disconnect the connectors with the translator power supplies, as some translators cannot cope with this action. The auxiliary input/output connector can be disconnected while switched on without damaging the module.
However, for safety reasons it is recommended that you turn off the auxiliary power supply before any type of disconnection.
Failure to follow this precaution can result in injury or equipment damage.
The module fixing screws and connectors must be correctly screwed in place in order to guarantee effective resistance to electrostatic and electromagnetic interference.
235
Installation
General precautions for wiring
General The power supply to sensors and actuators must be protected against overload or overvoltage by fast-blow fuses.
l l l when wiring use wires of sufficient size to avoid on-line voltage falls and overheating, keep sensor and actuator cables away from any source of radiation resulting from high-power electric circuit switching, all cables connecting the translators must be shielded, the shielding must be good quality and connected to the protective ground both for the module and the translator. Continuity must be ensured throughout connections. Do not transmit any other signals in the cable than those for the translators.
For reasons of performance the auxiliary inputs of the module have a short response time. You must therefore make sure that there is enough self-sufficient supply to these inputs to ensure the module continues to operate correctly in the event of a short power break. It is recommended that you use a regulated supply to ensure more reliable response times from the actuators and sensors. The 0 V supply must be connected to the protective ground nearest to the supply module output.

Description
Installation
Each module output signal is RS 485, for each output there is therefore a direct signal (+) and its complement (-). The outputs are TTL type current extraction compatible. The 5 V insulated voltage is only available, if necessary, to supply translator input and output. The 0 V is common to inputs and outputs. 5 V must only be used with translators with open collector outputs and TTL type inputs
(5 V insulated not provided by the translator).
Illustration:
+ output driver

- output input
The proposed type of connection is direct wiring by soldering onto the connector: the
TSX CAP S15 (See

comprising a SUB-D connector and its protective cover.

Connections
General There are several possible options for connecting the sensors/pre-actuators of the
TSX CFY 11 / 21 module. They can be connected directly by the TSX
CDP 301 / 501 (See
Connection using TSX CDP 301 or 501 strips, p. 199) strip or
via the Discrete TELEFAST pre-wiring system.
244
Installation
Connecting auxiliary inputs and outputs to processor.
General To ensure optimum operation, the event and reference point inputs have a weak immunity. It is recommended that you use contacts without bounce (proximity sensor for example).

Description
Installation
The emergency stop or end limit switch contacts are open.
End limit switch contacts are not contacts which have to be wired in series with the emergency input. End limit switch contacts are used to command movement stop with deceleration. The end limit switch (ELS+) stops movement in the +direction, the end limit switch (ELS-) stops movement in the- direction. It is therefore important to positions them at the correct end of the axis (see diagram below).

Availability of signals on TELEFAST
Illustration This diagram shows the availability of signals on TELEFAST:
Installation
(1) At the ABE-7H16R20 base, the position of the jumper wire determines the polarity of all terminals from 200 to 215: l l jumper wire in position 1 or 2: terminals 200 to 215 have + polarity, jumper wire in position 3 or 4: terminals 200 to 215 have - polarity,
(2) At the ABE-7H16R20 base, it is possible to add an optional ABE-7BV20 strip to create a second shared sensor (+ or - according to user’s choice).

Installation
Wiring precautions
General To ensure the best performance, inputs I0 to I5 are rapid inputs. If the actuator is a dry contact, the inputs must be connected by a twisted pair, or by a shielded cable if the sensor is a two or three-wire proximity detector.
The module includes as standard basic protection against short circuits or voltage inversions. However, the module cannot remain operational for long with an error.
You must therefore ensure that the fuses in series with the supply carry out their protective function. These are 1A maximum fast-blow fuses, the supply energy must be sufficient to ensure their fusion.
Important note: wiring of Q0 static outputs
The actuator connected to the Q0 brake output has its shared pin connected to supply 0 V. If for any reason there is a 0 V outage of the output amplifier supply
(e.g. poor contact or accidental unplugging), when the 0 V of the actuators remains connected to the 0 V supply, there may be enough mA output current from the amplifier to keep low-power actuators triggered.

Installation
Connection via
TELEFAST
This kind of connection is the most guaranteed, on the condition that the shared actuators are connected to the 200 to 215 shared points strip (jumper wire in position
1-2). In this case there can be no outage of the shared module without an outage of the shared actuators.
254
Installation
Connection using a TSX
CDP 301 / 501 pre-wired strand
This kind of connection must be carried out with the greatest care and attention. It is recommended that you take special care in wiring this cable, for example using the cable ferules on screw terminals. It may be necessary to double the connections in order to ensure permanent contacts. When the actuator supply is a long distance away from the modules and close to the shared actuators, there may be an accidental break of the link between the latter and the 0 V terminal of the module(s).
Illustration:

Critical wire
If there is a break of the supply section between A and B, there is a risk that the RL actuators may not remain operational. You must, if possible, double connections of
0 V supply to the modules.
