6.4.2. Analog Torque Command Operation
l You may control directly the output torque of the Motor with analog torque command in the
torque control mode.
à You may set dead band to the command voltage.
(Refer to “6.4.2.1. Dead Band Set to Analog Command.”)
à Voltage of analog torque command is ± 10V. Offsetting analog command is possible
using an adjusting pod (VR1) on the front panel of the Driver Unit or setting parameter
AF. (Refer to “6.4.2.2. Offsetting Analog Command.”
à The parameter AC selects the polarity of command voltage. (See Table 6-15.)
à Relation between the command voltage and the output torque of the Motor may be
changed with parameter AGT.
(Refer to Figure 6-28.)
