Section 4-8
Note (1) Speed Monitoring Unit
When the speed (feedback speed, command speed, or target speed) is
selected for the monitor type, the monitoring unit for position control/
torque control, and speed control is as follows:
For further details on operation timing, refer to 10-5 Speed Control .
(2) Torque Monitoring Unit
When the torque is selected for the monitor type, the monitoring unit for
position control, speed control, and torque control is as follows:
For further details on operation timing, refer to 10-6 Torque Control .
Note (1) Control data is used to monitor the control status of the Servo Drive. The
resolution of the monitor value depends on the specifications of the con-
nected Servo Drive.
