5.2.2.2 - MDX-RESOLVER
the mdX-ResolVeR option is used to manage the motor
speed feedback. It manages 2 to 8 poles resolvers.
Before installing or removing the MDX Speed
feedback option, or when it is necessary to
disconnect cables from the option, it is essential
for the drive to be switched off.
• General
• the mdX-ResolVeR 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.
Note
: leRoY-someR offers optional connection cables. For
more information, please get in touch with your usual leRoY-
someR contact.
Use a single twisted pair cable, shielded pairs with
an outer shield for the connection.
Connect the shield over 360 ° at both ends (grounding
bracket supplied with the option).

5.2.4 - Option installation
5.2.4.1 - grounding bracket
• to connect the option to the drive control board connector,
remove the black plastic protective cover.
• the bracket for connecting the option shielding is supplied
with each option. to attach it, screw the bracket, placing it on
top of the control cable shielding clamps (the shielding clamp
furthest the right should be removed).
