4.2 Dual Amplifier Modules
The Dual Amplifier modules are plug-in modules that contain the circuitry and amplify-
ing components for driving two of the motors in an AdeptSix robot. See Table 4-1.
NOTE: Connectors on E, F, and G amps have the same functionality.

1. Status
LEDs. The left column of LEDs is for the first motor
controlled by this module; the right column is for the second motor
controlled by this module. When an LED is on, it indicates the
following conditions:
High Volts On indicates high voltage to the amps is turned on.
PWM On indicates that current servo is on. It does not go on until
calibration is complete.
Low Volts On indicates the low voltage supply in the power
chassis is on.
Note: the three
LED pairs below indicate faults and are visible
momentarily before the system turns off.
Open Ckt Fault indicates that an open circuit in the motor leads
has been detected.
HV Sag/Over Temp Fault left
LED, when lit, indicates that the fault
was caused by a sag in voltage. The right
LED, when lit, indicates
the fault was caused by an over-temperature condition on the
amplifier heat sink.
Short Fault indicates that an over-current in the motor leads has
been detected.
2. Amplifier Control connector: the sMAI-to-Amp cable is installed
on this connector at the factory. This connector is covered when
shipped and users should not need to access it.
3. Motor Power Outlet connectors: the Arm Power cables are
installed on these connectors.
