Note
Installation and commissioning may only be performed in accordance with these
instructions by technicians with appropriate qualifications.
Additional measures are necessary if used in safety relevant applications, e.g. in
Europe the standards listed under the EC machinery directive must be observed.
Without additional measures in accordance with statutory minimum require
ments, the product is not suitable for use in safety-related sections of control
systems.
Please note that the configuration of the EMME-AS can be determined based
on the rating plate. Depending on the order, this motor contains a holding
brake (EMME-…-AS

) and either a singleturn-encoder (EMME-…-A

a multiturn-encoder (EMME-…-A

Function and application
The EMME-AS is a permanently excited, electrodynamic, brushless servo motor.
The EMME-AS is factory-fitted with an singleturn-encoder or a multiturn-encoder
depending on the order code.
The encoder supplies motor data, speed and position signals to a higher-order
controller in the form of analog and digital signals.
The motor must always be operated within its permitted characteristic curves
(

The EMME-AS is available with the following options:

Requirements for product use
Note
Improper handling can result in malfunctions.
Make sure that the specifications contained in this chapter are adhered to at
all times.
Compare the maximum values specified in these operating instructions with
your actual application (e.g. forces, torques, masses, speeds, temperatures).
The use of force to move the motor shaft will reduce the functionality of an op
tional integrated holding brake.
If necessary, also observe the assembly instructions provided with the mounting
components (e.g. gear units or couplings).
Ensure that all applicable safety regulations are adhered to, e.g. from trade
associations or national authorities.
Use the EMME-AS in its original state. Unauthorized product modification is not
permitted.
Take into account the prevailing ambient conditions at the location
(
è
Technical data).

Installation
Warning
Open cable ends on the rotating motor can, under certain circumstances, lead to
dangerous high voltages.
1. First leave the motor uncoupled from the driven mechanical component.
2. Make sure that the controller is switched off.
Cancelling the Controller Release signal is not sufficient.
3. Connect the EMME-AS completely to the controller as shown in the following
tables. Pre-assembled cables from Festo (
è
Accessories) offer sufficiently large
cable cross-sections as well as screening of the motor/encoder cable with an
earth contact on both sides.
