Figure 3: Configuring the switch-on current
Ensure that the supply voltage to the motor feedback system's DSL plug (7) is from
►
+7 V to +12 V.
NOTE
A suitable encoder shield connection to the ground or to the motor shield is required for
smooth operation.
For a motor feedback system with:
•
Spring plate stator coupling
coupling (14).
•
Elastomer stator coupling
wire (24) and a shield connection (25).
The motor feedback system has the following signals:
HIPERFACE DSL
®
interface:
•
DSL+: Encoder supply voltage with a modulated positive data signal.
•
DSL–: Encoder ground connection with a modulated negative data signal.
Temperature sensor:DSL–: Encoder ground connection with a modulated negative data
signal.
•
T+: Positive potential for the passive temperature sensor/ temperature resistor.
•
T+: Negative potential for the passive temperature sensor/ temperature resistor

(figure

(figure
