Description
This signal turns on when the power is switched on, Drive unit READY signal is turned off, [Cd.190] PLC READY signal in
turned on, or a machine OPR starts. This signal turns off when the machine OPR completes.
This signal turns on when a machine OPR completes normally. It turns off when the operation starts, Drive unit READY
signal is turned off, or [Cd.190] PLC READY signal is turned on.
This signal is used to interlock the command speed change function in the position-speed switching control. During the
position-speed switching control, this signal turns on when the position control is switched to the speed control. This signal
turns off when the next positioning data is processed, and during the JOG operation or manual pulse generator operation.
This signal turns on when an axis warning occurs and turns off when Axis error reset is turned on.
This signal turns on when a speed change request is issued with the new speed value being 0 and turns off when a speed
change request issued with a new speed value other than 0.
In the WITH mode, this signal turns on when the positioning data operation is started. In the AFTER mode, this signal
turns on when the positioning data operation is completed. This signal turns off with [Cd.7] M code ON signal OFF request.
When no M code is specified (When [Da.10] M code is 0), this signal remains off. With using continuous path control for
the positioning operation, the positioning continues even when this signal does not turn off. However, M code ON signal
ON (Warning code: 0992H) will occur. When [Cd.190] PLC READY signal is turned off, this signal also turns off. If the
operation is started while the M code is on, M code ON signal ON start (Error code: 19A0H) will occur.
This signal turns on when an error occurs, and turns off when the error is reset via [Cd.5] Axis error reset or [Cd.49] All
axes error reset.
This signal turns on when the positioning module starts the positioning processing since Positioning start signal is turned
on. (Start complete signal also turns on during OPR control.)
[Cd.184] Positioning start signal
Start complete
([Md.31] Status: b14)
This signal turns on for the time set in [Pr.40] Positioning complete signal output time from the instant when the positioning
control for each positioning data No. is completed. For the interpolation control, Positioning complete signal of the
interpolation axis turns on for the time set to the reference axis. (This signal does not turn on when [Pr.40] Positioning
complete signal output time is 0.) This signal will turn off if the positioning (including OPR), JOG operation, inching
operation, or manual pulse generator operation is started while this signal is on. This signal will not turn on when the
speed control or positioning is canceled midway.
