Set the time (positive direction) for torque to increase from "0" to reach the torque
limit value at speed-torque control and the time (negative direction) to decrease
to "0" from the torque limit value at speed-torque control during torque control or
continuous operation to torque control.

When the torque generation direction of servo motor is changed due to the
command torque change during torque control or continuous operation to torque
control, the operation is as follows.
• The torque output value is 0 [%] according to the setting value of command
torque time constant (negative direction). After that, the value becomes
command torque according to the setting value of command torque time
constant (positive direction).
