During T1 cartesian jogging, the correct speed pair is cartesian speed 250 mm/s and joint speed 10% of max.

• A. 50 mm/s and 5%
• B. 1000 mm/s and 50%
• C. 250 mm/s and 10%
• D. 10 mm/s and 250%

Answer: (C)

In cartesian jogging, you control two things: how fast the end-effector moves in Cartesian space (the linear speed of the tool) and how fast the joints are allowed to move relative to their maximum (a percentage). The end-effector speed sets the actual forward motion, while the joint-speed limit keeps the motors from pushing too hard or moving too quickly for the controller to track precisely.

Choosing 250 mm/s for the end-effector gives a solid, practical pace—fast enough to be productive but not so fast that precision and stability are compromised. Setting the joint speed to 10% of max keeps the joints from rushing and helps maintain smooth tracking, reducing the risk of overshoot, excessive torque, or hitting mechanical limits. This pairing strikes a balance between responsive motion and safe, controllable operation.

The other options would either be too slow or exceed what the joints can safely deliver: for example, a much higher Cartesian speed paired with a large joint-percent could demand joint performance beyond what the hardware can sustain; a very low cartesian speed with an unrealistically high percentage isn’t feasible, and a combination like 10 mm/s with 250% is not physically possible since joint speeds cannot exceed their maximum.
