5.2 - Add-on options
the
POWERDRIVE MD2CS
control board is designed to be
plugged with various optional modules. several options can
be combined:
• speed feedback option (see section 5.2.1)
• Fieldbus option (see section 5.2.2)
• additionnal I/o option (see section 5.2.3)
5.2.1 - Fieldbus modules
Fieldbus modules can be used to communicate with the
corresponding networks respective. they can be integrated
in and are supplied by the drive.
two types of options are offered (with the same functionality):
•
MDX option: option to be fitted to the control board (white)
• cm module: compact module to be integrated in an
existing mdX board (grey)

• Check that the optional module is in good
condition: never install a damaged module in the
drive.
• Before installing or removing the option, or when it is
necessary to disconnect the cables connected to it, it is
essential for the drive to be switched off.
CAUTION:
• Do not break the cut-out part.
• A MDX-Fieldbus option can never take the MDX-
ENCODER terminal block.
For more information, refer to the manuals for the relevant
options available on www.leroy-somer.com.
5.2.2 - Speed feedback option
5.2.2.1 - MDX-ENCODER
the mdX-encodeR option is used to manage the motor
speed feedback. It manages incremental encoders with or
without commutation channels.
Before installing or removing the MDX Speed
feedback option, or when it is necessary to
disconnect the cables connected to the option, it is
essential for the drive to be switched off.
5.3.2.2 - General
• Use a shielded cable for connection, and connect the
shield over 360° using the grounding bracket (see section
• the mdX-encoder module can manage the motor Ptc
thermal probe via terminals t1 and t2. In this case, some
parameters need to be set. Refer to parameter
Mtr.06 (05.70)
in the commissioning manual ref. 4617.
• terminals 0 and 0\ are not used.
Note
: leRoY-someR offers optional connection cables. For
more information, please get in touch with your usual leRoY-
someR contact.
CAUTION: The encoder cable shielding must always be
connected to the grounding bracket supplied with the
option.
