CPU Irregularity Detection
Irregularity of CPU that controls the motor is detected by the watchdog timer. The
system CPU and the motor controlling CPU inside the Manipulator are also
designed to constantly check each other for any discrepancies. If a discrepancy is
detected, the dynamic brake circuit is activated.
Memory Check-sum Error Detection
The dynamic brake circuit is activated when a memory check-sum error is detected.
Overheat Detection at the Motor Driver Module
The dynamic brake circuit is activated when the temperature of the power device
inside the Motor Driver module is above the nominal limit.
Relay Deposition Detection
The dynamic brake circuit is activated when relay deposition is detected.
Over-Voltage Detection
The dynamic brake circuit is activated when the voltage of the Manipulator is above
the normal limit.
Power Supply Voltage Drop Detection
The dynamic brake circuit is activated when the drop of the power supply voltage
is detected.
Temperature Anomaly Detection
The temperature anomaly of the Manipulator is detected.
