RVSVC2 Relationship between rotative direction of master motor and slave at
Torque Tandem Control.
0 : master motor and slave motor rotate in the same direction
1 : master motor and slave motor rotate in the opposite direction
Set polarity of velocity command and velocity feedback at Torque
Tandem Control.
Remark
*1 It is not necessary to set this bit of slave SPM (setting of master SPM
is transferred via communication between SPMs).
*2 Torque Tandem Control doesn’t work correctly if setting of this bit is
inadequate.
Illegal velocity polarity alarm (SPM alarm d0) occurs in case of
inadequate setting.

Remark
Torque Tandem Control doesn’t work correctly if this bit is “1”.
Be sure to set to “0”.
