  Connectors – Input / Output

Spindles required the use of a VFD (Variable Frequency Drive) to function. These VFDs are also called spindle inverters. The VFD takes the power from the wall and creates a frequency with voltage and current to spin the spindle. The frequency can be controlled to control the RPM of the spindle

NOTE: Do not directly plug it into electricity power, Spindle can be connected only to Frequency Inverter!

Connector Description Drawing
1 Power line: Three-color lines connected with UVW phases. gdl80 atc drawing1a
1 * Temperature control line – Thermistor: 110°C thermistor two-wire
connected (brown / brown) with the temperature-controler unit.
1 Ground: Yellow and green wires for Ground.
2 Cooling water inlet: Max. 0,8 Bar (8m pump head), 8/6mm hose
3 Air Inlet: dust removal, pressure 2-3 Bar (6/4 hoses)
4 ** Two proximity switches: NPN for tool-loading and tool-unloading (normally open) N.O.
5  Air seal: pressure 1-2 Bar (4/2 hoses)
6  Cooling water outlet: 8/6mm hose
7  Air inlet for Tool Change pneumatic cylinder, 6-7 Bar (6/4 hoses)

Do not attempt to wire your VFD or spindle on your own. Consult with a professional electrician before following the diagram!


  * PTC single-core Thermistor parameter
  -20-25ºC   ≤300Ω
  ≤90ºC   ≤750Ω
  105ºC   ≤1650Ω
  110ºC   Rated operating themperature
  115ºC   ≥3990Ω
  ≥125ºC   ≥12KΩ
  ≤160ºC   Maximum storage temperature

** Wiring method of the proximity switch: Brown wire connect to +24VDC, blue wire connect to 0VDC and black wire is a signal (you can use this signal wire to detect clamping mechanism position


Caution:

  • The electrical spindle must be mounted at its clamping position,
    otherwise it may cause the damage of bearing
  • The tool changing must be done when the electrical spindle stopped
    completely; the manual tool changing button shall not be enabled
    when electrical spindle still rotating; otherwise, the electrical spindle
    may get stuck
  • The compressed air needs to be clean and dry with filtering precision as
    0.1μm!The air sealing is normally open.
    And it is suggested to apply two steps of filtering with filtering precision
    as 0.5μm and 0.1μm respectively. And the air filter shall be equipped with
    self-discharging device.
