(4) Bit definition of Status DO 2
Z-phase already passed
0: Z-phase unpassed after start-up
1: Z-phase passed once or more after start-up
Zero speed detection
S_ZSP turns on when the servo motor speed is at 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 will turn on. When the servo is
off, TLC will be turned off.
The Status DO cannot be used in the position mode or velocity mode.
During IPF
S_IPF turns on during an instantaneous power failure.
Under proportional control
S_PC turns on under proportional control.
External dynamic brake output
When the dynamic brake needs to operate, S_DB turns off.
Home position return completion 2 (incremental system)
When a home position return completes normally, S_ZP2 turns on. S_ZP2 is always on unless the home
position is erased.
It will be off with the following conditions.
1) [AL. 69 Command error] occurs.
2) Home position return is not being executed.
3) Home position return is in progress.
Home position return completion 2 (absolute position detection system)
If a home position return completes once, S_ZP2 is always on. However, it will be off with the following
conditions.
1) [AL. 69 Command error] occurs.
2) Home position return is not being executed.
3) Home position return is in progress.
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] was changed.
8) [Pr. PA01 Operation mode] was changed.
The values in bit 1, 2, 5, 7, 9, and 11 to 14 at reading are undefined.
