Variable Statusword.xxx
The Statusword indicates the current status of the external encoder.
These values are no longer updated when the external encoder is disabled. The
values shown correspond with the last status registered at the time the enable
signal was reset.
Bit
No.
Variable Meaning of the status TRUE
0 Statusword.DriveEnabled
The external encoder is enabled (Mode = 1 at the input
parameter of "MC_ExternalEncoder")
1 Statusword.HomingDone The axis is homed, i.e. "MC_ExternalEncoder" was
successfully completed in Mode = 2 to 6
2 Statusword.Done No command currently executed
3 Statusword.SuperImposedCommand Irrelevant for the external encoder.
4 Statusword.Error
At least one error has occurred (ErrorID = 8xxx).
Warning do not change the Error = FALSE status.
5 Statusword.Errorstop The external encoder will be/was locked due to an error.
Eliminate the cause and acknowledge the error.
6 Statusword.Stopping Irrelevant for the external encoder.
7 Statusword.Standstill The velocity of the external encoder (absolute value) is lower
than the set standstill limit.
8 Statusword.PositioningCommand Irrelevant for the external encoder.
9 Statusword.SpeedCommand Irrelevant for the external encoder.
10 Statusword.SynchrCommand Irrelevant for the external encoder.
11 Statusword.Homing The bit is set at the start and reset at the end of homing
("MC_ExternalEncoder" Mode = 2 to 6)
12 Statusword.FollowUpControl Irrelevant for the external encoder.
13 Statusword.ConstantVelocity Irrelevant for the external encoder.
14 Statusword.Accelerating Irrelevant for the external encoder.
15 Statusword.Decelerating Irrelevant for the external encoder.
16 Statusword.RequestRestart Parameters of the external encoder were changed and do
not take effect until after the next restart (MC_Reset with
Restart = TRUE).
17 Statusword.Simulation Irrelevant for the external encoder.
18 Statusword.CyclicInterface Irrelevant for the external encoder.
19 Statusword.EncoderValid The actual position values of the external encoder is valid (of
particular importance due to the startup phase of absolute
value encoder.)
20 Statusword.SpeedMode
Always FALSE for the external encoder.
21 Statusword.TorqueLimiting Irrelevant for the external encoder.
22 Statusword.SupImpSynchrCommand Irrelevant for the external encoder.
Variable ActualPosition
Shows the current position of the external encoder.
The position is no longer updated when the external encoder is disabled. The
indicated position corresponds with the last position before the enable signal was
reset.
