Function
Turns OFF when an error is detected.
Controls the brake. The brake is released when the signal
turns ON.
Allocation can be changed to general-purpose output signals
(/SO1+, /SO1-).
Used for general-purpose output.
Note: Set the parameter to allocate a function.
The allocation of an output signal to a pin can be changed in
accordance with the function required.
Encoder output pulse signals for two-phase pulse train with
90° phase differential
Origin pulse output signal
Connects to the 0 V pin on the control circuit of the host con-
troller.
Connected to frame ground if the shielded wire of the I/O sig-
nal cable is connected to the connector shell.
Do not use these pins.
Function
For hard wire baseblock input.
Baseblock (motor current off) when
OFF.
ON when the /HWBB1 and the
/HWBB2 signals are input and the
SERVOPACK enters a baseblock state.
