1.4 8LVA - Compact servo technology
The 8LVA motor series is the perfect choice when it comes to in-
stalling servo motors in extremely tight spaces. Equipped with either
a resolver or digital EnDat 2.2 interface, these motors can meet the
absolute highest demands. With their low moment of inertia, motors
in the 8LVA series are designed to be highly dynamic and are dis-
tinguished by their outstanding intrinsic acceleration characteristics.
Additional noteworthy features include low cogging and a high over-
load capability. These motors have IP54 protection standard but are
also available with IP65 protection. They can optionally be equipped
with a holding brake. Designed for use with ACOPOSmicro servo
drives, these motors offer extremely high performance and are some
of the most compact on the market. 8LVA servo motors are recom-
mended for a wide range of applications and provide an optimal
price/performance ratio in the power range up to 1 kW.
1.4.1 Standards and guidelines
The motors are intended for use in commercial plants and subject to the following standards and guidelines:
Standards
EN 60034- 1
Rotating electrical machines - measurement and operating behavior
EN 60034- 5
Degrees of protection provided by the integral design of rotating electrical machines
EN 60034- 6
Rotating electrical machines - Cooling types
EN 60034- 7
Rotating electrical machines - Classification of types of construction, mounting arrangements
EN 60034- 11
Rotating electrical machines - Thermal protection
Guidelines
Low voltage directive 2014/35/EU
The motors correspond to the low voltage directive (conformity).
EMC directive 2014/30/EU
To operate the motor in accordance with its intended use, it must comply with the protection requirements of the
EMC directive. Proper installation (e.g. spatial separation of signal lines and power cables, shielded lines and
cables) is the responsibility of the plant installer and system provider. If operating with a power converter, then
the EMC guidelines of the power converter, encoder and brake manufacturers must be observed.
RoHS Directive 2011/65/EU
The motors in this series comply with the RoHS Directive (2011/65/EU) for the assessment of electrical and
electronic products with respect to the restriction of hazardous substances.
Note:
National, local and plant-specific regulations must also be taken into account!
1.4.2 Type plate
The type plate clearly identifies each motor. The motor number ensures traceability.
Note:
•
The type plate must be visible at all times.
•
The type plate is not permitted to be removed from the motor.
1.4.2.1 Embedded parameter chip
All relevant mechanical and electrical information and data is contained in the EnDat encoder used for B&R mo-
tors. This means that the user does not have to configure settings on the servo drive. As soon as the encoder is
connected to the servo drive and the power supply for the electronics is switched on, the motor is automatically
identified. The motor transmits its nominal values and limit values to the servo drive. The drive then uses these
to independently calculate the current limit values and current control parameters necessary for safe operation of
the motor. The user only has to optimize the speed and position controllers. The integrated commissioning envi-
ronment in B&R Automation Studio
TM
provides all necessary support.
