VELO (Internal velocity preset)
W.E.ST. Elektronik GmbH
Commands Parameter Defaults Units Description
velo x x= 1000… 10000 10000 0,01%
Here the maximum velocity can be limited internally. The limitation function corresponds to the external
velocity preset if VS was parameterized with EXT.
VS (internal or external velocity preset)
Commands Parameter Defaults Units
vs x x= EXT|INT INT
Switch over between internal and external velocity preset.
In case of external velocity preset external voltages at PIN 9 and PIN 10 are used. An input of 10V corresponds
with 100% speed.
VRAMP (ramp time for the external velocity)
Commands Parameter Defaults Units
vramp x x= 1… 2000 50 ms
Here the ramp time for velocity changes will be set.
Operating shocks can be reduced when changing the external velocity.
VMODE (Activation of the NC mode)
Commands Parameter Defaults Units
vmode x x= ON|OFF OFF
With this parameter the NC mode (almost closed loop controlled velocity) will be activated. In OFF state
the stroke depended deceleration is active; the velocity preset limits the output signal.
In ON state the positioning demand value is generated by a profile generator and the axis drives to the
target position with the defined velocity. The stroke time is defined by the parameter th.
