a. Torque command and generated torque
A relationship between the applied voltage of the analog torque command (TC) and the
torque generated by the servo motor is shown in Fig. 3-7. Generated torque limit values
will vary about 5% relative to the voltage depending on products.
Generated torque may vary at the voltage of -0.05V to +0.05V. Table 3-4 shows the torque
generation directions determined by the forward rotation selection (RS1) and reverse ro-
tation selection (RS2) when the analog torque command (TC) is used.
