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 EMMS-AS can be determined based
on the rating plate. Depending on the order, this motor contains a holding
brake (EMMS-...-ASB/AMB/ARB) and either an encoder (EMMS-...-AS.../AM...)
or a resolver (EMMS-...-AR...).
Electrostatic discharges onto the motor of more than 3.2 kV can sporadically
result in malfunctions of the motor.

Function and application
The EMMS-AS is a permanently excited, electrodynamic, brushless servo motor.
The EMMS-AS is factory-fitted with an encoder or a resolver depending on the
order code.
The encoder supplies motor data, speed and position signals to a higher-order
controller in the form of digital signals.
The resolver supplies an analogue signal to a higher-order controller; this signal
allows the controller to ascertain speed and position information.
The motor must always be operated within its permitted characteristic curves.

Servo motor EMMS-AS has been designed for driving positioning systems. The
holding brake of the EMMS-AS-...-ASB/AMB/ARB is not suitable for braking the
motor.

Transport and storage
• Ensure storage conditions as follows:
– short storage times
– cool, dry, UV and corrosion resistant (
• Take into account the weight of the EMMS-AS.
Depending on the design the EMMS-AS can weigh over 22 kg.

Requirements for product use
Note
English
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.
• Ensure that all applicable safety regulations are adhered to, e.g. from trade
associations or national authorities.
• Use the EMMS-AS in its original state. Unauthorized product modification is not
permitted.
• Take into account the prevailing ambient conditions at the location (
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 EMMS-AS completely to the controller as shown in the following
aJ
tables. Pre-assembled cables from Festo (
cable cross-sections as well as screening of the motor/encoder/resolver cable
with an earth contact on both sides.
