Dual B5 Amplifier Module
The Dual B5 Amplifier module is a plug-in module that contains the circuitry and ampli-
fying components to drive two of the motors in an Adept 550 robot. Each Dual B5 ampli-
fier can drive one major axis (J1 or J2) and one minor axis (J3 or J4).
In a typical Adept 550 robot system, there are two identical Dual B5 Amplifier modules in
the Adept PA-4 power chassis. The amplifier module on the left-hand side, called
Module 1, drives motors 1 and 3. The amplifier module on the right-hand side, called
Module 2, drives motors 2 and 4.

Status LEDs. The left-hand column of LEDs is for the first
motor controlled by this module; the right-hand column is
for the second motor controlled by this module. When an
LED is turned on it indicates the following conditions:
High Volts On indicates the 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.
Open Ckt Fault indicates that an open circuit in the motor
leads has been detected.
HV Sag/Over Temp indicates that either the input voltage
has dropped below the specified level or an over-tempera-
ture fault has been detected on an amplifier module.
Short Fault indicates that an over-current in the motor leads
has been detected.
Control Signal connector – the "VJI to Amp" cable connec-
tors are installed here. See Chapter 5 for more details.
Motor Power Output connector – the "motor power" cable is
installed here. See Chapter 5 for more details.
