Power Supply For The Itnc 530 - HEIDENHAIN iTNC 530 Technical Manual

3.5 Power Supply for the iTNC 530

3 – 12
The UV 1x0 or the UV 105 power supply unit supplies the iTNC 530 with
power.
Power is supplied through X69 and, with the UV 105, in addition through a 5 V
terminal on the CC 422.
For information on the UV 1x0 supply units, refer to the Technical
Manual "Inverter Systems and Motors."
Whether the UV 1x0 supply unit is sufficient or whether a UV 105 is needed
as additional equipment, depends on the current consumption of the used
units.
