E49
Torque Monitor (Polarity Select)
When using the calculated torque of V/f control and torque command value of the vector control, generally,
the driving side of the torque polarity is at positive, and the braking side is at negative. When the rotation
changes from normal to inverse by the lifting load, etc., the torque also changes from the driving side to the
braking side, and the polarity inverses. When the torque data is traced by the PC loader, the polarity of the
torque command value changes, and the data do not become the consecutive data. When 0 is selected for
this function code, the forward drive and reverse braking are handled at positive, and forward braking and
reverse braking are handled as negative. Therefore, the continuity of the torque data can be secured.
Table 5.4-84
E49 Data Torque Monitor Polarity
0 Torque polarity (forward drive and reverse braking are +, forward braking and reverse drive are -.)
1 Drive is +, Brake is - (default value)
Related data are as follows. All of these are displayed or transferred with the polarities. Judge the meanings
of signs by using the set values of E49.

* When the terminal Ao (polarity select) (o73) setting is 0: only in case of both polarity, the output data of
E49 polarity is obtained.
