Electromagnetic
brake interlock MBR When using the device, set operation delay time of the electromagnetic
brake in [Pr. PC16].
When a servo-off status or alarm occurs, MBR will turn off. DO-1
Speed command
reached SA When a command speed is within a target speed at servo-on status, SA
will be on.
When the command speed is 0 r/min (mm/s), this will be continuously on.
When the command speed is in acceleration/deceleration or at servo-off
status, SA will be off. DO-1
Home position
return
completion ZP When a home position return completes normally, ZP (Home position
return completion) will be on.
This will be off with the following conditions in the incremental system.
1) SON (Servo-on) is off.
2) EM2 (Forced stop 2) is off.
3) RES (Reset) is on.
4) At alarm occurrence
5) LSP (Forward rotation stroke end) or LSN (Reverse rotation stroke end)
is off.
6) Home position return is not being executed.
7) Software limit is being detected.
8) Home position return is in progress.
If once home position return is completed in the absolute position detection
system, ZP (Home position return completion) will be the same output
status as RD (Ready).
However, it will be off with the above 1) to 8) and the following 9) to 14).
9) The home position return is not performed after [AL. 25 Absolute
position erased] or [AL. E3 Absolute position counter warning] occurred.
10) The home position return is not performed after the electronic gear
([Pr. PA06] and [Pr. PA07]) was changed.
11) The home position return is not performed after the setting of [Pr.
PA03 Absolute position detection system selection] was changed from
"Disabled" to "Enabled".
12) [Pr. PA14 Rotation direction selection/travel direction selection] was
changed.
13) [Pr. PA01 Operation mode] was changed.
14) [Pr. PT08 Home position return position data] or [Pr. PT28 Number of
stations per rotation] was changed.
DO-1
Rough match CPO When a command remaining distance is lower than the rough match output
range set with [Pr. PT12], CPO will be on. This is not outputted during base
circuit shut-off. CPO turns on with servo-on.
DO-1
Position range
output POT When an actual current position is within the range set with [Pr. PT21] and
[Pr. PT22], POT will be on. This will be off when a home position return
does not complete or base circuit shut-off is in progress. DO-1
Temporary stop PUS When a deceleration begins for a stop, PUS will be on by TSTP
(Temporary stop/restart). When you enable TSTP (Temporary stop/restart)
again and start operation, PUS will be off. DO-1
Travel
completion MEND When the droop pulses are within the in-position output range set with [Pr.
PA10] and the command remaining distance is "0", MEND will be on.
MEND turns on with servo-on.
MEND is off at servo-off status. However, MEND will not be off in the
indexer method. DO-1
Position end PED When the droop pulses are within the position end output range set with
[Pr. PA10] and the command remaining distance is "0", PED will be on.
When MEND (Travel completion) is on and ZP (Home position return
completion) is on, PED (Position end) will be on.
When ZP (Home position return completion) is on with servo-on status,
PED will be on.
PED is off at servo-off status. DO-1
SYNC
synchronous
output SOUT When the status is waiting for input of the program SYNC (1 to 3), SOUT
will be on. When PI1 (Program input 1) to PI3 (Program input 3) turn on,
SOUT will be off. DO-1
