Connector JC10: Temperature sensor and digital inputs/Hall effect sensor
Caution:
This cable must be insulated (no contact) from the power and the mains.
The inputs (except TSD) of this connector are galvanically insulated by opto-couplers.
The inputs and outputs must be connected to an Extra Low Voltage circuit only
(SELV).
Caution:
This connector must be handled in an ESD protected environment, only.
Remark:
The temperature sensor cable connected to the DSC2P must be shielded (see
§3.7.1
).
3.1.3.1
Digital inputs
The 3 digital inputs (DIN5 to DIN7) can be used additionally to the 6 digital inputs already present on connector
JC9 or can be connected to a digital Hall effect sensor.
Digital Hall effect sensor
3 digital inputs (H1+, H2+ and H3+) are used to connect a digital Hall effect sensor. This sensor is used for the
motor commutation thanks to three digital signals (one for each Hall effect sensor). On the following graph, the
Hall signals and the sine voltages between the motor phases are displayed:
The digital Hall effect sensors (H1, H2 and H3) must be connected as shown below:
An external pull-up (resistor) must be added per sensor. A resistor of 1.5 k
Ω
(1/4 W) must be used if Vext is
equal to +15VDC. If the user needs to supply the Hall effect sensor with another voltage, please contact ETEL
to define the value of the resistor.
