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
This bit can be used on the servo amplifiers with software version A3 or later.
1
The value at reading is undefined.

S_ZSP
Zero speed detection
The S_ZSP turns on when the servo motor speed is at zero speed or less. Zero speed can be changed with
[Pr. PC17].
4
S_VLC
Limiting speed
The S_VLC turns on when the speed reaches the limit on any of the parameter between [Pr. PC05 Internal
speed limit 1] to [Pr. PC11 Internal speed limit 7].
This turns off when SON (Servo-on) turns off.
5
The value at reading is undefined.
6

8
S_PC
Under proportional control
S_PC turns on under proportional control.
9
The value at reading is undefined.

S_ZP2
Home position return completion 2
When a home position return completes normally, S_ZP2 turns on. S_ZP2 is always on unless the home
position is erased.
In the incremental system, this signal 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.
The S_ZP2 is always on even when the home position return is completed only once in the absolute
position detection system. However, it will be off with one of the above 1) to 3) conditions and together with
the following:
4) The home position return is not performed after [AL. 25 Absolute position erased] or [AL. E3 Absolute
position counter warning] occurred.
5) The home position return is not performed after the electronic gear ([Pr. PA06] or [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.
This bit is enabled in the profile mode, point table mode, and indexer mode.
