3. SIGNALS AND WIRING
The speed may be changed during rotation. In this case, the values set in parameters No.PC01 and
PC02 are used for acceleration/deceleration.
When the internal speed command 1 to 7 is used to command the speed, the speed does not vary with
the ambient temperature.
(c) Speed reached (SA)
As in section 3.6.2 (2).
3.6.5 Speed/torque control change mode
Set " 3" in parameter No.PA01 to switch to the speed/torque control change mode.
(1) Control change (LOP)
Use control change (LOP) to switch between the speed control mode and the torque control mode from an
external contact. Relationships between LOP and control modes are indicated below.
(Note) LOP Servo control mode
0 Speed control mode
1 Torque control mode
Note. 0: off
1: on
The control mode may be changed at any time. A change timing chart is shown below.

Note. When the start (ST1 ST2) is switched off as soon as the mode is changed to
speed control, the servo motor comes to a stop according to the deceleration time
constant.

As in section 3.6.2 (1).
(3) Torque limit in speed control mode
As in section 3.6.1 (5).
