6.1.2 Distribution of output signals
The output signal can be distributed to the output port of the input/output signal connector (CN1). Allocation is
set through Pn50E, Pn50F, Pn510, Pn514.
When the distribution of output signals is changed for use
Important
No detected signal is in "OFF" state. For example, during speed control, the positioning completion output
(/COIN) signal is "OFF".
If the polarity of the brake control output (/BK) signal is reversed and used with positive logic, the brake will
stop when the signal line is broken. When this setting has to be adopted, please be sure to make action
confirmation to ensure there is no safety problem.
When multiple signals are distributed on the same output loop, they will be output by XOR logic.
Examples of Changes in Output Signal Distribution
After the positioning completion output (/COIN) signal assigned to CN1-OUT3 is set to invalid, an example of
assignment of the servo ready output (/S-RDY) signal is as follows.
Pn50E = n.03
↓
Pn50E = n.3

0
Confirmation of Output Signal Status
The status of the output signal can be confirmed through output signal monitoring.
Output signal monitoring operation reference: 8.3.2 Monitoring of input and output
6.1.3 Servo Alarm Output (ALM) Signal
The servo alarm output (ALM) signal is the signal output when the servo drive detects a fault.
Important
Please design an external circuit that turns OFF the power supply of the servo-driven main circuit through the
alarm output when a fault occurs.

6.1.4 Warning output (/WARN) signal
The servo drive is provided with alarms and warnings.
The alarm indicates that there is an abnormality in the servo drive and the operation needs to be stopped
immediately.
The warning is an announcement before the alarm occurs and does not need to stop running.
The warning output (/WARN) signal refers to the warning before the alarm occurs

6.1.5 Rotation detection output (/TGON) signal
The rotation detection output (/TGON) signal is a signal indicating that the servo motor is running.
