Single-axis Velocity Control
This section describes the operation of velocity control for single axes.
Velocity control is used to constantly move an axis at the specified velocity. You can also specify the
acceleration rate, deceleration rate, and jerk. To stop an axis, use the MC_Stop instruction or execute
another motion instruction. If you specify a target velocity of 0, the axis will not move but the axis status
will indicate that it is moving. If any other motion control instruction is executed with multi-execution of
instructions during velocity control, the operation will switch only after reaching the target velocity.
The MC Function Module uses Position Control Mode of the Servo Drive and sends target position
commands to achieve the specified target velocity.
The position control loop is enabled in the Servo Drive. Therefore, as the command velocity slows
down, e.g., due to disturbance, and the following error increases, the velocity will change to eliminate
this following error.
For details, refer to the MC_MoveVelocity (Velocity Control) instruction in the
NJ-series Motion Control
Instructions Reference Manual
(Cat. No. W508).
