P3.23 Torque detection reference

Range: 0.0～200.0%【100.0%】

Note:

◆If motor torque is equal to or more than the range of torque detection reference, the

output of terminal is valid. If the ac motor torque is less than 80% of reference, the

output of terminal is invalid, as shown in Fig. 5-3-11.

Range: 0～9999【0】

Note:

◆If the counting value is bigger than the value defined by P3.24, the output of terminal

is valid, as shown in Fig. 5-3-12.
