x Bit No. 8: Follow the same procedure as in bit No. 6 for abnormal stopping when controlling the
torque.
x Bit No.09: Selects 0 or 1 after completing zero speed stop is selected.
x Bit No. C/D: Selects the conditions for activating the mode switch.
When the mode switch activates, the speed control will be switched to P control. This
is, however, available only for controlling the speed.

In torque controlling:
x Controls output torque from

x Speed limit can be

Speed can be controlled in
both CCW and CW

In speed control:

=REFERENCE=
x Outside the limit
speed range, the
torque proportional to
the difference with the
limit speed is fed back
negatively to take
back the speed to
within the limit range.
Therefore, the motor
speed limit value
varies according to
the load condition.
