Parameter Details
 Set the relation between the voltage applied to the torque reference input (TREF1: CN1 pin 14,
TREF2: CN2 pin 16) and the motor speed.
Refer to "5-3 Torque Control" (P.5-14) for more information on torque command scale.
Explanation of Set Values
 Reverse the polarity of the torque command input (REF/TREF1: CN1 pin 14 or PCL/TREF2: CN1
pin 16).
 Corresponding speed limit values during torque control is shown in the table below.
