6.4.6 Speed Detection Level and Detection Width (SD
LVL
: C1-21, SD
HYS
: C1-22)
When the Motor speed is below the set value, the output signal (SDET) turns ON. At this time, the U1-10
operating status display on the Digital Operator is as shown below. The speed detection signal level
(C1-21) can be set between 0% and 100%, and the speed detection signal detection width (C1-22) can be
set between 0% and 10%. (The percentage of the rated speed (C1-26) is displayed.)

6.4.7 Torque Detection Signal Operation Level (TD
LVL
: C1-23)
This constant is the set value for the torque detection signal (TDET) operation level. (The signal turns ON
when the torque is below the set value.) When TDET is ON, the U1-10 operating status display on the Digi-
tal Operator is as shown below. The torque detection signal operation level can be set between 5% and
120%, taking 30 minutes rated torque to be 100%. As shown in the following diagram, the operation point
has an hysterisis of ±10%.

6.4.8 External Control Torque Limit Level (TL
EXT
: C1-24)
This control constant is used when limiting the torque externally. The limit can be set between 5% and
120%, taking the rated torque for 30 minutes as 100%.
6.4.9 Motor Code Selection (MTR: C1-25)
The Motor code sets the level of Motor control constants stored in the Inverter memory. The Motor codes
are shown in the table 6.4. When changing the Motor code settings, check that the new value matches the
Inverter Unit capacity. If the selected Motor code and the Inverter capacity do not agree, error code AL-E0
(Motor Code Selection Error) will be displayed. Also, if no Motor code has been registered, error code
AL-E1 (Motor Code Not Registered) will be displayed.
If the motor being used is not listed in the following table, please contact your Yaskawa representative for
motor code information.
