Description
Driving power to the motor is
electronically shut off by responding to
the input signal from the safety
controller. This function is available
even without a safety encoder
installed.
Deceleration starts by responding to
the input signal from the safety
controller. The STO function is
activated after the specified time to
confirm the stop state elapses. This
function is available even without a
safety encoder installed.
Deceleration starts by responding to
the input signal from the safety
controller. Deceleration is monitored
based on the motor deceleration rate.
The STO function is activated after the
specified time to confirm the stop state
elapses.
Deceleration starts by responding to
the input signal from the safety
controller. The SOS function is
activated after the specified time to
confirm the stop state elapses.
Deceleration starts by responding to
the input signal from the safety
controller. Deceleration is monitored
based on the motor deceleration rate.
The SOS function is activated after the
specified time to confirm the stop state
elapses.
The motor position is monitored so
that the motor stops within the
specified range from the stop position.
Power is still supplied to the motor
during the SOS function.
The motor speed is monitored so that
the predetermined speed limit is not
exceeded. If the limit is exceeded, the
STO function is activated.
The motor rotation direction is
monitored. If the direction changes
from the specified one, the STO
function is activated.
The motor travel distance (position) is
monitored. If the motor travels over the
specified distance (position range),
the STO function is activated.
A safety output signal is output when
the motor speed is within the speed
limit.
When the STO or SS1 command is
input, a safety output signal is output
to control an external brake. When the
STO command is input, this function is
available even without a safety
encoder installed.
The motor speed is monitored so that
the maximum speed is not exceeded.
If the maximum speed is exceeded,
the STO function is activated.
