Under zero speed
When the servo motor speed is at zero speed or slower, S_ZSP turns on. 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, S_TLC will be turned off.
The Status DO cannot be used in the position mode or velocity mode.
During IPF
During 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
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, it turns off with one of the following conditions.
1) Servo alarm [AL. 69 Command error] occurs.
2) LSP (Forward rotation stroke end) or LSN (Reverse rotation stroke end) is off in
the profile mode.
3) Home position return is not being executed.
4) Software limit is detected in the profile mode.
5) Home position return is in progress.
If a home position return completes once in the absolute position detection
system, S_ZP2 is always on. However, it will be off with one of the conditions 1) to
5) or the following.
6) The home position return is not performed after [AL. 25 Absolute position erased]
or [AL. E3 Absolute position counter warning] occurred.
7) The home position return is not performed after the electronic gear ([Pr. PA06] or
[Pr. PA07]) was changed.
8) The home position return is not performed after the setting of [Pr. PA03 Absolute
position detection system selection] was changed from "Disabled" to "Enabled".
9) [Pr. PA14 Rotation direction selection/travel direction selection] was changed.
10) [Pr. PA01 Operation mode] was changed.
