6.6 Others

6.6.1 Applying the speed limit

The maximum motor speed in each mode (Position, Speed, and Torque) is determined by the
6
internal 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 more details.
The speed limit is applicable only in Torque mode (T or Tz) for controlling the motor's maximum
speed. If you are using the external analog voltage in Torque mode, you can use the available DI
signals to set SPD0 and SPD1 for the motor speed limit value (internal parameters). If there is no
DI signals available, use the analog voltage input for the Speed limit command. When you set
P1.002.X (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 more details.
The torque limit is applicable in Position mode (PT or PR) or Speed mode (S) for limiting the
motor torque output. If you are using the external pulse in Position mode or using the external
analog voltage in Speed mode, you can use the available DI signals to set TCM0 and TCM1 for
the torque limit command (internal parameters). If there is no DI signals available, use the
analog voltage input for the Torque limit command. When you set P1.002.Y (disable / enable
Torque limit function) to 1, the Torque limit function is enabled. The timing diagram is shown as
follows.
