10. OBJECT DICTIONARY
Bit definition of status DO2
Bit Symbol
Z-phase already passed
0 S_ZPASS 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
Zero speed detection
3 S_ZSP
S_ZSP turns on when the servo motor speed is zero speed or less. Zero speed can be changed with [Pr.
PC07].
Limiting speed
When the speed reaches the speed limit value in the torque mode, S_VLC turns on. When the servo is off,
4 S_VLC
this turns off.
The Status DO cannot be used in the position mode or velocity mode.
Under cam control
5 S_CAMS
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
Under proportional control
8 S_PC
S_PC turns on under proportional control.
9 The value at reading is undefined.
External dynamic brake output
10 S_DB
When the dynamic brake needs to operate, S_DB turns off.
Clutch on/off status
11 S_CLTS 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".
Clutch smoothing status
The output depends on the setting in [Cam control data No. 42 - Main shaft clutch smoothing system] as
follows:
0: Direct
12 S_CLTSM
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.
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
13 S_CPCC
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.
Home position return completion 2
When a home position return completes normally, this turns on. This is always on unless the home position is
erased.
In the incremental system, it turns off with one of the following conditions.
1) [AL. 69 Command error] occurs.
2) Home position return is not being executed.
3) Home position return is in progress.
If a home position return completes once in the absolute position detection system, this is always on.
15 S_ZP2
However, it will be off with one of the conditions 1) to 3) or the following conditions 4) to 8).
4) The home position return is not performed after [AL. 25 Absolute position erased] and [AL. E3 Absolute
position counter warning] occurred.
5) The home position return is not performed after the electronic gear ([Pr. PA06] and [Pr. PA07]) was
changed.
6) The home position return is not performed after the setting of [Pr. PA03 Absolute position detection system
selection] was changed from "Disabled" to "Enabled".
7) [Pr. PA14 Rotation direction selection/travel direction selection] was changed.
8) [Pr. PA01 Operation mode] was changed.
