• Bit definition of status DO2
*1 This is available with servo amplifiers with software version A8 or later.

Description
0
S_ZPASS
Z-phase already passed
0: Z-phase unpassed after start-up
1: Z-phase passed once or more after start-up
1
The value at reading is undefined.
2
3
S_ZSP
Zero speed detection
S_ZSP turns on when the servo motor speed is zero speed or less. Zero speed can be changed with [Pr. PC07].
4
S_VLC
Limiting speed
When the speed reaches the speed limit value in the torque mode, S_VLC turns on. When the servo is off, this turns off.
The Status DO cannot be used in the position mode or velocity mode.
5
S_CAMS
Under cam control
It turns on when the control switches to the cam control. It turns off when the control switches to the normal positioning
control.
6
The value at reading is undefined.
7
8
S_PC
Under proportional control
S_PC turns on under proportional control.
9
The value at reading is undefined.
10
S_DB
External dynamic brake output
When the dynamic brake needs to operate, S_DB turns off.
11
S_CLTS
Clutch on/off status
It turns on with clutch-on.
It is always off when [Cam control data No. 36 - Main shaft clutch control setting] is set to "_ _ _ 0".
12
S_CLTSM
Clutch smoothing status
The output depends on the setting in [Cam control data No. 42 - Main shaft clutch smoothing system] as follows:
0: Direct
1: Time constant system (Exponent)
Always on in clutch-on status
It turns off when the clutch is off and the smoothing is completed.
13
S_CPCC
Cam position compensation execution completed
It outputs clutch smoothing status.
The output depends on the setting in [Cam control data No. 42 - Main shaft clutch smoothing system] as follows:
0: Direct
Always off
1: Time constant system (Exponent)
Always on in clutch-on status
It turns off when the clutch is off and the smoothing is completed.
14
The value at reading is undefined.
15
Home position return completion 2
1. When incremental system is set
When home position return completes normally, S_ZP2 turns on.
When home position return starts or [AL. 69 command error] occurs, S_ZP2 turns off.
With [Pr. PT01] set to the incremental value command method in the positioning mode (point table method and indexer
method), S_ZP2 turns off when the following conditions are met.
1) Servo-off status (servo off, EM1 or EM2 off, alarm generated, STO off, [AL. E9 Main circuit off warning] occurrence)
2) Stroke limit is off
3) During software limit detection
2. When absolute position detection system is set
When home position return completes normally, S_ZP2 turns on.
When home position return starts or [AL. 69 command error] occurs, S_ZP2 turns off.
S_ZP2 also turns off when any of the following conditions are met.
1) [AL. 25 Absolute position erased] occurrence
2) [AL. E3 Absolute position counter warning] occurrence
3) [Pr. PA01], [Pr. PA06], [Pr. PA07], [Pr. PA14], [Pr. PT01 (_ x _ _)], [Pr. PT08], [Pr. PT28], or [Pr. PT47] is changed.
However, when [Pr. PT01] is set to the incremental value command method in the positioning mode (point table method
and indexer method), an absolute position detection system cannot be built. Check the parameter setting values and
revise if necessary.
