During T1 cartesian jogging, the Cartesian speed limit is 250 mm/s.

• A. It depends on model
• B. True
• C. False
• D. Not specified

Answer: (B)

In teaching or T1 Cartesian jogging, the motion that matters is the end-effector’s speed in Cartesian space, not the individual joint speeds. The system is designed so that this Cartesian velocity is limited to 250 mm/s to keep manual control safe and predictable, giving the operator enough time to react and ensuring gentle, controllable motion during teaching.

So the statement is true because 250 mm/s is the defined safety limit for Cartesian jogging in T1 mode. The other options don’t fit: the limit isn’t something that varies by model in this teaching context, it isn’t left unspecified, and it isn’t incorrect to say the limit is 250 mm/s.
