1)
The specific values for non-linearities apply to an ambient temperature of 20 °C and a stator coupling installed free of stress.
2)
A safety variant of the DSL Master IP Core must be implemented in the regulator in order to connect to a drive controller, "HIPERFACE DSL
Safety" implementation manual (8017596).

3)
Starting from when a permitted operating voltage has been reached.
4)
Without sensor tolerance; at –17 °C to +167 °C: NTC ± 2 K (103 GT); PTC ± 3 K (KTY 84/130)
5)
Duration of voltage ramp between 0 V and 7 V.
6)
When using the suggested input circuit as described in the "HIPERFACE DSL® Safety" implementation manual (8017596).
7)
The mission time can also be limited by the bearing service life specific to the application.
8)
Permitted when using an elastomer stator coupling. When using the spring plate stator coupling, mounting without any tension is assumed.
9)
The defined measuring point on the motor feedback system must be used for the measuring the operating temperature. (see dimensional
drawing)
10)
According to the listed standards, EMC is guaranteed if the motor feedback system with mating plug inserted is connected to the central
grounding point of the motor controller via a cable shield.
If other shielding concepts are used, users must perform their own tests. Class A device.
11)
IP54 required in installed state
For more detailed information on the exact configuration of your machine/unit, please contact your responsible SICK subsidiary.

13)
The safety related accuracy indicates the maximum positioning error limit with which the safety functions can be supported.
