7.5 Speed-Torque Control

The following chart shows the operation timing.
When the mode is switched from continuous operation to torque control mode to speed control mode, the
torque command during continuous operation to torque control is invalid. As shown in the figure above, when
the target is pressed in continuous operation to torque control direction, if the mode is switched to speed
control, torque is output to the torque limit value.
Execute the following either if such operation will be a problem.
• Set the speed command which is in opposite direction of continuous operation to torque control direction in
the speed command device before switching to the speed control mode.
• Change the torque limit value to the lower value by torque limit value change request (CHGT) before
switching to the speed control mode.
