Power Supply Connections
Power to the Aries Controller may be supplied in one of two ways: a single-
source to the Motor Input Power (Mains) screw terminals with the factory-
installed jumpers in place; or removal of the jumpers and application of
separate sources to the Motor Power terminals and to the Control Power
terminals.
When a separate mains power is applied to the drive/controller, the internal
control board remains powered when the primary Motor Power source is
disconnected. When operated in this configuration, the Control Power input
performs a “keep-alive” function. The keep-alive circuit maintains several
important functions, including the following:
• Communications
• Diagnostics
• Motor position feedback
• Brake relay in brake mode
• Drive I/O signals
Earth Ground
Under normal operation, no current should flow through the Protective Earth
connection.
Important — Make the Protective Earth ground connection directly by
means of a low-impedance path less than or equal to 0.1 ohm (with no fuses
or other devices).
Single-Source (Motor Input Power) Connections
Figure 16 shows how to connect the external 120/240 VAC Motor Power
single-source to the Input Power connector.
