Auxiliary voltage connection

Mains potential-free auxiliary DC V= (4 A) to +24 V= (2 A) ±10 %.
Observe the type plate!
The auxiliary voltage has
•
Galvanic connection to the logic voltage
•
Galvanic protective separation from all internal supply voltages and from the housing.
•
Internal self-healing fuse
•
EMC filter
External fuse for line protection only
Input voltage 12.. 24 V DC
GND24
Residual ripple 10 %
Inrush current max. 4 A
Nominal current 1.4 A
0.9 A
Connect the negative terminal of the power supply unit to earth.
Attention:
•
In addition to the internal supply current (1.4 A at 12 V / 0.9 A at 24 V), the total current of the
outputs (DOUT) must be supplied by the power supply unit.
•
If the auxiliary voltage is less than 10.5 V, the error message hardware error 1 (Power Fault)
appears.
•
If the auxiliary voltage is less than 10 V, including brief voltage interruptions, the internal power
supply unit switches off.
- Temporary data in the RAM memory is deleted.
- Digital speed and torque setpoints are set to 0.
- Message OK in the status is dark.
•
Firmware download only with power switched off!
•
Only switch auxiliary voltage and/or power voltage when BAMOCAR is locked.
