[Vel Rate Lim]
The rate at which a velocity command is
incremented or decremented per unit of accel/
decel time (in seconds).
Important:
The velocity rate limit command
overrides a position controller velocity rate limit
command. This parameter is automatically
changed to its maximum value when [Motor
Type] is selected.

[Vel Ref Fract]
Lower 16 bits of [Vel Ref Whole] (parameter 204),
forming a 32 bit velocity reference.
Parameter Numbers 208, 209, 210, 211
Parameter Group Linear List
Display Units rpm
Parameter Type Read/Write
Linkable Yes
[Vel Ref Whole]
This parameter is the present value of digital
velocity reference and must be the destination of
link for any data to be output.
Parameter Numbers 204, 205, 206, 207
Parameter Group Vel Cmd Data
Display Units rpm
Parameter Type Read/Write
Linkable Yes
Minimum Value -8000.0 rpm
Maximum Value +8000.0 rpm
Default Value 0.0 rpm
[Vel Source]
Selects the velocity command source(s) within
the drive. Automatically changed when [Mode
Sel] is changed (for convenience during
commissioning).
For Example: Axis 0, 1, 2 could be set in (#0)
analog reference while axis 3 could be set in (#1)
digital input.
