6.6 Others

6.6.1 Applying the speed limit

The maximum speed in each mode (Position, Speed, and Torque) is determined by the internal
6
parameter (P1.055). The methods for using the Speed limit command and Speed command are
the same. You can use either the external analog voltage or the internal parameters (P1.009 -
P1.011). Refer to Section 6.3.1 for descriptions.
The speed limit is applicable only in Torque mode (T) for controlling the motor's maximum speed.
If you are using the external analog voltage in Torque mode, the DI signals are available and you
can set SPD0 - SPD1 for the motor speed limit value (internal parameters). If not, use the analog
voltage input for the Speed limit command. When you set P1.002 (disable / enable speed limit
function) to 1, the Speed limit function is enabled. The timing diagram is shown as follows.

6.6.2 Applying the torque limit

The methods for using the Torque limit command and Torque command are the same. You can
use either the external analog voltage or the internal parameters (P1.012 - P1.014). Refer to
Section 6.4.1 for descriptions.
You can use the torque limit in Position mode (PT and PR) or Speed mode (S) to limit the motor
torque output. If you are using the external pulse in Position mode or using the external analog
voltage in Speed mode, the DI signals are available and you can set TCM0 and TCM1 for the
torque limit command (internal parameters). If not, use the analog voltage input for the Torque
limit command. When you set P1.002 (disable / enable torque limit function) to 1, the Torque
limit function is enabled. The timing diagram is shown as follows.
