Which keyboard combination can simulate Play mode with continuous operation?

• A. FWD + BWD
• B. CTRL + ALT
• C. INTERLOCK + TEST START
• D. SHIFT + ENTER

Answer: (C)

Engaging safety and initiating the run sequence are two steps that must be combined to start continuous operation. The safety interlock ensures guards or doors are closed and the operator is ready. When you press the test start while the interlock is active, the controller interprets this as a deliberate command to begin or resume execution in Play-style continuous operation, so the program runs continuously until a stop is issued.

Other keyboard combos don’t trigger this mode: moving keys would jog or steer the axis, a system-level CTRL+ALT is not the start signal for Play, and SHIFT+ENTER isn’t used to start continuous operation on these controllers.
