WORKING BL Processing in
progress ... indicates that a function has been started with Start or Travel Plus/Mi-
nus, and is active.
S
“Processing in progress” is set with:
– “Jogging”, “Control” mode during the movement up to stand-
still after cancelation of R+, R–
– Reference-point approach mode, during approach until reference
point is reached
– “MDI”, “Incremental relative mode”, during the positioning
process or while functions of the MDI block are being processed
– Automatic mode, during processing of a traversing program
until the end of the program.
S
“Processing in progress” is deleted:
– by errors and restarts
– by mode changes.
– after axis standstill
WAIT_EN WFG Warten auf ex-
terne Freigabe ... takes effect only if a digital input has been parameterized by means of
MD34 (see Section 9.8.1).
Set: if the enable input has not yet been set or has been reset when a
movement has been activated.
DT_RUN T-L Verweilzeit
läuft ... only active in Automatic and MDI mode.
As soon as a traversing block with a dwell time has been processed,
(T-L) is output during the programmed time period.
PR_BACK PBR Programmbear-
beitung
rückwärts ... is set after a Start in Automatic mode if a program is being processed
in reverse.
MODE BAR Active mode The selected mode is not fed back until it is internally active. For a
mode change, for example, a movement must be stopped before
another mode can become active (does not apply to switching
between Automatic and Automatic single-block modes).
SYNC SYN Synchronism ... module is synchronized (see Section 9.6.4)

MSR_DONE ME Measurem. End ... signals an executed measurement (see Section 9.3.10)

FR+

plus
Travel Minus
... means the axis is traveling in the direction of increasing actual values
or in the direction of voltage output “+” in OL control mode.
... means the axis is traveling in the direction of decreasing actual values
or in the direction of voltage output “–” in OL control mode.
S
As soon as an active travel movement is pending, the messages
(FR+) or (FR–) are output depending on the traversing direction.
They can only be pending as alternatives.
S
“Travel Plus” or “Travel Minus” is actuated at the start of the accel-
eration phase and remains active until the axis comes to a standstill
or the POS_ROD target area has been reached.
