9. CONNECTION TO SERVO OR SPINDLE
When a single servo amplifier is shared by multiple Power Mates, servo
alarm 401 (servo amplifier ready signal OFF) may occur in the cases
1) When multiple Power Mates share a single servo amplifier
Power Mate Power Mate
The servo amplifier does not turn on the servo amplifier ready signal until
all the Power Mates have started.
When one Power Mate enters one of the following states, the servo
amplifier turns off the ready signal, causing servo alarm 401 to occur in
the other Power Mates:
D The power is turned off.
D A servo alarm occurs.
D The system enters the emergency stop state.
D The controlled axis detach signal is turned on.
If power–up for one Power Mate is delayed when the Power Mates are
turned on, or if a follow–up operation, performed after power–up,
requires too much time when an absolute pulse coder is being used, servo
alarm 401 also occurs in the other Power Mates.
