1. Safety
Safety and Installation (T, VT / EPSON RC+ 7.0) Rev.15 29
Low Power Mode
The motor power is reduced in this mode.
Executing a power status change instruction will change to the restricted (low
power) status regardless of conditions of the safety door or operation mode. The
restricted (low power)
status ensures the safety of the operator and reduces the
possibility of peripheral equipment destruction or damage caused by careless
operation.
Dynamic Brake
The dynamic brake circuit includes relays that short the motor armatures. The
dynamic brake circuit is activated when there is an Emergency Stop input or when
any of the following errors is detected: encoder cable disconnection, motor overload,
irregular motor torque, motor speed error, servo error (positioning or speed
overflow), irregular CPU, memory check-sum error and overheat condition inside
the Motor Driver Module.
Motor Overload Detection
The dynamic brake circuit is activated when the system detects that the load on the
motor has exceeded its capacity.
Irregular Motor Torque (out-of-control Manipulator) Detection
The dynamic brake circuit is activated when irregularity with motor torque (motor
output) is detected (in which case the Manipulator is out of control).
Motor Speed Error Detection
The dynamic brake circuit is activated when the system detects that the motor is
running at incorrect speed.
Positioning Overflow -Servo Error- Detection
The dynamic brake circuit is activated when the system detects that the difference
between the Manipulator’s actual position and commanded position exceeds the
margin of error allowed.
Speed Overflow -Servo Error- Detection
The dynamic brake circuit is activated when the Manipulator’s actual speed is
detected to mark an overflow (the actual speed is outside the nominal range) error.
