NJ/NX-series CPU Unit Motion Control User’s Manual (W507)
The following two types of axis velocities are used in the MC Function Module.
* This value is given if the Velocity actual value (606C hex) is mapped in the PDOs and assigned to the Actual Cur-
rent Velocity.
A velocity is given in command units/s. The command unit is the value obtained from unit conversion of
the position display unit and the electronic gear.
*1 A CPU Unit with unit version 1.05 or later and Sysmac Studio version 1.06 or higher are required to use this
parameter.
*2 The maximum jog velocity is used as the command velocity if you specify a velocity command value that is
greater than the maximum jog velocity.
9-5-2 Velocity
Types of Velocities
Velocity type Definition
Command velocity This is the velocity that the MC Function Module outputs to control an axis.
Actual velocity This is the velocity calculated in the MC Function Module based on the actual posi-
tion input from the Servo Drive or encoder input.

Velocity Unit
Axis Parameters That Are Related to Velocities
Parameter name Function Setting range Default
Maximum Velocity Specify the maximum velocity for the axis. If a
target velocity that exceeds the maximum
velocity is specified for an axis motion instruc-
tion, the axis will move at the maximum veloc-
ity.
Positive long reals 400,000,000
Start Velocity
*1
Set the start velocity for each axis.
Set a value that does not exceed the maximum
velocity.
(Unit: command units/s)
Positive long reals 0
Maximum Jog Velocity
Set the maximum jog velocity for each axis.
*2
Set a value that does not exceed the maximum
velocity.
(Unit: command units/s)
Positive long reals 1,000,000
Velocity Warning Value Set the percentage of the maximum velocity at
which to output a velocity warning for the axis.
No velocity warning is output if 0 is set.
(Unit: %)
0 to 100 0
Actual Velocity Filter
Time Constant
Set the time period to calculate the average
travel of the actual velocity in milliseconds. The
average travel is not calculated if 0 is set.
(Unit: ms)
Use this to reduce variations in the actual cur-
rent velocity when axis velocity is slow.
0 to 100 0
