4) Speed limit in torque control mode

a. Speed limit value and speed

The speed is limited to the limit value set in parameter No. 8 (internal speed limit 1) or the

value set in the applied voltage of the

analog speed limit (VLA). A relationship between the analog speed limit (VLA) applied

voltage and the servo motor speed is as in 3)a, (3) in this section.

b. Connection diagram

Generally connect as shown in Fig. 3-16. When a precision speed command is required,

refer to 3b, (3) in this section.

c. Speed selection 1 (SP1) and speed limit value

Use speed selection 1 (SP1) to select between the speed set to the internal speed limit 1

and the speed set to the analog speed limit (VLA) as indicated in Table 3-10.

When the internal speed limit 1 is used to command the speed, the speed does not vary

with the ambient temperature.

d. Limiting speed (VLC)

As in 3)d, (3) in this section.

5) Torque control in torque control mode

As in 1), (3) in this section.

6) Torque limit in torque control mode

As in 2), (3) in this section.
