(2) Machine ready, Emergency stop release and Alarm release
It is the functional switch to release the emergency stop and to start up the initial
operation of the machine after turning on the power of the machine.
1) Machine ready switch
When pressing this switch under the state of being not activated
the emergency stop switch and electrical torque limiter, The LED is
flickering under the basic condition for machine ready, and if Servo
Ready Signal in CNC is ON, then The LED is ON.
<Check the state of Machine Ready LED>
① Machine Ready Relay is ON. (LED flickering)
② Electric contactor of CNC power supply circuit is ON, and the power will be
supplied to PSM in CNC. When CNC becomes Servo Ready state, LED is ON.
③ When CNC becomes Servo Ready state normally, X axis brake will be released.
Note 1) Be sure to check whether the emergency stop switch is released or not
before pressing the machine ready switch. Without releasing the
emergency stop switch, Machine ready cannot be done.
2) Emergency Stop Release Switch
There are some possibilities that the machine can be an
emergency stop state by electrical torque limiter due to the
increasing of load by the interference with workpiece or
mechanical interference during the axis jogging or automatic
operation of the machine.
In this case, in order to release the emergency stop state, press
the Machine Ready switch simultaneously during pressing the
emergency stop release switch. And when emergency stop state is
occurred owing to over travel of axis, press the Machine ready
switch simultaneously during pressing the emergency stop release
switch. It makes the machine to Machine Ready State and then
move the axis to the inside of travel stroke using feeding handle.
Normally alarm reset cannot be released by the above mentioned
operation of these switches until all of the alarm causes are
completely removed. In order to reset the alarm, be sure to
remove all of the alarm causes first.
