The "parking axis" firmware command (C1600) causes the encoder power
supply to be switched off.
Sense function
The EC encoder evaluation allows correcting the 5 V supply voltage at the
encoder. It is thereby possible, within certain limits, to compensate for voltage
drops on the encoder cable.
Functional principle: The current consumption of the connected encoder sys‐
tem generates a voltage drop due to the ohmic resistance of the encoder ca‐
ble (line cross section and line length). This reduces the signal at the encoder
input. The actual value of the 0 V encoder potential at the encoder is meas‐
ured via a separate "Sense" line (Sense-) and fed back to the drive controller.
Thus, the drive controller can influence the voltage of the encoder supply.
For correct "Sense" evaluation, the encoder supply lines "+5V"
and "GND_Encoder" have to have the same line cross section.
If the encoder has a "Sense-" connection, connect the "Sense"
line at this connection. A possibly existing "Sense+" connection is
not used.
If the encoder has no "Sense" connection, apply the 0 V encoder
potential to the "Sense-" line on the encoder side.
