a) A regenerative unit has the following fault detection functions:
• Detecting disconnection in a regenerative resistor
• Detecting faults in a regenerative transistor
• Detecting overvoltage
b) When one of these fault detection functions operates, the internal alarm relay is actu-
ated. Then, the circuit between output terminals C1 and C2 is opened.
c) Form a sequence so that the Servopack power is turned OFF when the alarm relay is
actuated.
