Function
Servo alarm: Turns OFF when an error is detected.
Brake interlock signal
Controls the brake. The brake is released when the signal turns ON.
Allocation can be changed to general-purpose output signals (/SO1+, /SO1-).
General-purpose output signal.
Note: Set the parameter to allocate a function.
Signal ground:
Connected to frame ground if the shield wire of the I/O signal cable is connected to the connector shell.
Phase-A signal
Dividing ratio can be set by parameter
(proper line receiver is SN75175 manufactured by Texas instruments or the equivalent
corresponding to MC3486)
Phase-B signal
Phase-C signal
Terminal not used. Do no connect.
Function
Hard wire baseblock input 1
Hard wire baseblock input 2
Monitored circuit status output 1:
ON when the hard wire baseblock function is normally activated.
