3.9.2 Output Signal Configuration
a) Default
The function of each output signal is configured by the user and is set by parameters Pn613
～
Pn615. The default functions are as follows:
Function code
CN1 Pin No.
Default function
Pn613
25/26
0x00: Servo ready
Pn614
27/28
0x01: Positioning completed
Pn615
29/30
0x02: Consistent speed
b) Negation
1. Common switch output signal inversion function, take the servo ready signal (/S-RDY) as an
example, default setting Pn613=0x00, servo ready and then the output signal is ON; change the
setting Pn613=0x100, the servo is ready, then the output signal is OFF.
2. The alarm output signal (ALM) is the output of the fixed Pin No.The default setting is Pn622.1=0.
If the servo alarm occurs, the output signal will be OFF. If the change is set to Pn622.1=1, the
servo alarm will output the signal ON.
3.9.3 Confirming the Output Status
The status of the output signal can be confirmed by the output signal monitor (Un101). The Un101
segment display and corresponding Pin No.s are as follows:
Display
LED
Pin No.
Signal Name
1
CN1-31
、
32
ALM
9 8 7 6 5 4 3 2 1
Up: OFF
Down: ON
Codes
Cautions
！
1. Pn622.1 indicates the first bit of parameter Pn622, see the explanation of function code parameter.
2. No output signal is "invalid" state. Eg: Speed control, positioning completion (/COIN) signal is "invalid".
3. If the polarity of the brake signal (/BK) is reversed and used with positive logic, the brake will not operate
when the signal line is disconnected. When this setting has to be used, be sure to check the operation to
ensure that there are no safety problems.
4. When multiple signals are assigned to the same output circuit, they will be output in heterogeneous logic.
