Kinetix VP Low Inertia Servo Motors with 063…165 mm Frame Size
Performance Level (PL) and Safety Integrity Level (SIL)
For safety-related control systems, Performance Level (PL), according to EN ISO 13849-1, and SIL levels, according to IEC EN 61508 and
EN 62061, include a rating of the system's ability to perform its safety functions. All of the safety related components of the control system must be
included in a risk assessment and the determination of the achieved levels.
Refer to the EN ISO 13849-1, IEC EN 61508, and EN 62061 standards for complete information on the requirements for PL and SIL
determination.
Safety-related Parameters
A motor that is equipped with a Hiperface DSL functional safety-rated feedback sensor is designed to maintain the functional safety rating of the
feedback sensor attached. The safety parameters of the feedback sensors are as follows.
Motor Installation
Motor installation must comply with all local regulations and use of equipment and installation practices that promote safety and electromagnetic
compatibility:
• All motors include a mounting pilot for aligning the motor on a machine.
• Preferred fasteners are stainless steel.
Change Connector Orientation
Kinetix VP low-inertia motors use a connector style that integrates the power, brake, and feedback signals within a single connector. You can
identify the connector style by the variable number in the motor catalog string. For example, in catalog number VPL-A1303F-CJ
1
2AA, the
1
indicates a SpeedTec, right-angle, 325° rotatable connector (see
Catalog Number Explanation
on
page 2
).
The rotatable connector housing lets you move the connector into a position that best protects the connection from environmental contaminates
and provides easy access.

ATTENTION:
Unmounted motors, disconnected mechanical couplings, loose shaft keys, and disconnected cables are dangerous if power is applied. Identify (tag-
out) disassembled equipment and restrict access to (lock-out) the electrical power.
Before applying power to the motor, remove the shaft key and other mechanical couplings that could be thrown from the shaft.
ATTENTION:
Verify that cables are installed and restrained to prevent uneven tension or flexing at the connector. Provide support at 3 m (10 ft) intervals
throughout the cable run.
Excessive and uneven lateral force at the cable connector can result in the connector’s environmental seal opening and closing as the cable flexes.
ATTENTION:
Connectors are designed to be rotated into a fixed position during motor installation, and remain in that position without further adjustment.
Strictly limit the applied forces and the number of times the connector is rotated to make sure that connectors meet the International Protection (IP) rating as
outlined in
Environmental Specifications
on
page 22
.
ATTENTION:
Excessive force can damage the connector. Do not pull on the cable and do not use tools, such as pliers or vise-grips, to rotate the connector. Use
your hands to rotate the connector.
