12. Precautions for Use

12.2 Push Force of the Vertical Axis

Set the push force of the vertical axis by referring to the graph below.

Push-motion operating speed 10 mm/sec

 Use the PUSH command to perform push-motion operation involving the vertical axis. If push-motion

operation is performed without using the PUSH command, the life of the driving part may be shortened or

damage or vibration may result.

 Push force can be changed by driver card parameter No. 38, “Torque limit during positioning.”

 When performing push-motion operation, keep the speed to 10 mm/sec or below.

If the speed exceeds 10 mm/sec, provide a shock-reducing mechanism to keep the vertical axis from

receiving shock.

 The graph of push force and push torque limit during positioning shows characteristics when no load is

installed on the vertical axis. In downward push-motion operation, the applicable push force increases by

the load mass.

In upward push-motion operation with the inverse specification, the applicable push force decreases by the

load mass.

 Push force is controlled by servo motor current. No control is implemented based on feedback of push

force.

 Push force is subject to a variation of approx. 5%.
