Motor Supply Connector
DANGER: Shock and Fire Hazard!
Electrical wiring must be designed and installed in accordance with local electrical safety regulations to prevent the risk of fire and electrical shock.
If you have a combination of Aerotech drives with AC and DC motor supplies that use the same connector, Aerotech recommends that you key the Motor Supply connectors and mating cables. Refer to Motor Supply Keying for more information.
Motor power is applied to the DC+ and DC- terminals of the Motor Supply connector.
The DC+ input is internally connected to a 5 A fuse.
Use twisted pair wiring to minimize radiated noise emissions (refer to Minimizing Noise for EMC/CE Compliance). For inrush limiting, you must power up control and motor supply simultaneously.
Refer to Fuse Specifications for the internal fuse part numbers.
WARNING: Verify that all ground connections are installed correctly before you apply power to the iHXA4/HXA4.
