2. SIGNAL DESCRIPTIONSHANDLING
41
(1) Preparation completion signal MA
[Classification]
Input signal <Xx+2#7> (common to both the peripheral equipment
control and direct command interfaces)
[Function]
This signal indicates that the servo amplifier unit is ready to operate.
[Input condition]
The signal becomes 1 when:
1. Self--diagnosis in the servo amplifier unit completes normally
when the power is switched on.
The signal becomes 0 when:
1. The power to the servo amplifier unit is switched off.
2. A control unit error such as a CPU or m emory failure is detected.
(2) S ervo preparation completion signal SA
[Classification]
Input signal <Xx+1#6> (common to both the peripheral equipment
control and direct command interfaces)
[Function]
This signal indicates that the servo amplifier unit is ready to operate.
Conversely, if this signal is not issued, the servo amplifier unit is not
operating.
[Input condition]
The signal becomes 1 when:
1. Self--diagnosis in the servo system completes normally when the
power to the control unit is switched on.
2. A servo alarm (if any has occurred) is reset.
3. An emergency stop condition (if any has occurred) is reset.
The signal becomes 0 when:
1. The power to the control unit is switched off.
2. A servo alarm condition is detected.
3. An emergency stop is effected.
4. The V READY OFF alarm ignore signal (IGNVRY) is set to 1,
bit 0 (SAK) of parameter No. 004 is set to 0, and the ready signal
of the servo amplifier unit is turned off.
NOTE
In the servo --off state, the SA signal rema ins at 1 unless a
condition which resets it to 0 occurs.
