z
Dynamic brake
Dynamic brake circuit consists of a relay that switches the connection of motor power
line to make a short-circuit on the motor side or to connect to the AC servo driver.
When emergency stop is input, or the following malfunction is detected, the dynamic
brake activates and stops the rotation of motor.
z
Overheating detection
A thermostat inside the controller detects overheating.
z
Encoder discontinuity detection
Detects discontinuity of the signal wire from the motor encoder to the controller.
z
Overload detection
Detects loads that exceed the capacity of the motor.
z
Torque irregularity detection
Detects irregular motor output.
z
Speed irregularity detection
Detects irregularities in motor speed.
z
Servo overflow detection
Detects the difference between the position reference and the current position of the
manipulator.
z
Motor lock detection
Detects failure of the motor to respond to motion commands.
z
Control power source irregularity detection
Detects voltage irregularity of control power source of +5V,
±
12V and +24V.
z
Primary power source irregularity detection
Detects dropped voltage of AC200V motor main power.
z
CPU irregularity detection
Detects CPU’s irregularity that controls system with a watchdog timer. System con-
trolling CPU and motor controlling CPU always watches over each other.
z
Memory irregularity detection
Detects check sum error of memory.
