5.2 Outputs
5.2.1 +5 VDC output voltage «
V
CC
Hall»
An internal auxiliary voltage of +5 VDC is provided for:
Ö
Hall sensor supply voltage «V
CC
Hall»
Ö
For external set value potentiometer (recommended value: 10 k
Ω
)
Ö
Gating the signals: «Enable» and «Direction»
The output is thermal overload protected against short circuit.
+5 VDC output voltage
Pin number [6] «V
CC
Hall»
Referenced to Ground
Pin number [5] «Gnd»
Output voltage
+5 VDC ± 5 %
Max. output current
35 mA
5.2.2 Status indication «Ready»
The «Ready» output can be used to report the state of operational readiness
or a fault condition to a master control unit.
In normal cases (no fault) the output is switched to 5V.
Ready (no fault)
5 V
In case of a fault the output is switched to Ground.
Fault (not ready)
0 V (Gnd)
Possible reason for a fault message:
Ö
Undervoltage
Fault message occurs in case supply vV
CC
< 6.5 VDC.
To reset the fault condition the amplifier must be disabled and the supply
vV
CC
must be higher than 6.5 VDC.
Ö
Overvoltage
Fault message occurs in case supply vV
CC
> 30 VDC.
To reset the fault condition the amplifier must be disabled and the supply
vV
CC
must be lower than 29 VDC.
Ö
Thermal overload
Fault message occurs in case
power stage temperature exceeds > 95°C.
To reset the fault condition the amplifier must be disabled and the power
stage temperature must fall below 75°C
Ö
Invalid Hall sensor signals
The amplifier recognizes invalid conditions in the Hall sensor inputs
during the power-up. To reset the fault condition the amplifier must be
disabled and the Hall sensors must be wired correctly.
The output «Ready» is protected against short circuit.
