6.13.3 Speed control
ADD SPEED FUNCT
Speed control
[101] Spd threshold + [FF]
[102] Spd threshold - [FF]
[103] Threshold delay [ms]
[104] Set error [FF]
[105] Set delay [ms]
Two speed control messages are provided: - when a particular, adjustable speed is not exceeded.
- when the speed corresponds to the set rference value
Parameter description No.

* This function can be assigned to a programmable digital output.
Spd threshold + Switch point for the “Speed not exceeded” for clockwise rotation of the drive in the
units defined by the Factor funtion.
Spd threshold - Switch point for the “Speed not exceeded” for counter-clockwise rotation of the drive
in the units defined by the Factor funtion.
Threshold delay Setting of a delay time in milliseconds which is active when the speed is lowered within
the limits of the set threshold.
Spd threshold Message “Set speed not exceeded” (via a programmable digital input)
High Speed not exceeded
Low Speed exceeded
Set error Defines a tolerance band around the speed reference in the units specified by the Factor function.
Set delay Setting of a delay time in milliseconds which is active when the speed is lowered within
the limits of the set threshold.
Set speed Message “The speed corresponds to the reference value” (via a programmable digital output)
High Speed corresponds to the reference value
Low Speed does not corresponds to the reference value
The message “The speed corresponds to the reference value” refers to the total reference value in front of the
Speed ref speed regulator and to the Ramp Ref ramp reference when the ramp is selected.
When the references are lower than ± 1 %, the signal is always low!
