7.1.4 Parameterise speed mode
The f ollowing parameters (FCT) can be parameterised for the speed mode:
Settings
Description
Analogue Input
Scaling
1)
Value for scaling (linear axis: mm/s or rotative axis: rpm) of the
analogue setpoint value (± 10 V) in a speed setpoint value page 186.
Offset
1)
Value for the height of the voltage shift “rotational speed/speed
characteristic cur ve” to the zero point page 186.
Safe Zero
1)
Threshold value for the analogue setpoint value range in whic h the
rotational speed/speed characteristic curve is valued as rest (linear
axis = 0 mm/s or rotative axis = 0 rpm) page 186.
Input malfunctions (e.g. offset fluctuations, noise, etc.) ca n be
suppressed or a defined rest of the drive c an be paramete rised.
If the motor controller is operated via an external control circuit, the
value “0 V” should be parameterised as a Saf e Zero to ensure the
stability of the external control circuit.
Setpoint value selection/speed setpoint value ramp
Ramp Type Selection of the ramp type
Dependent on the ramp type, the parame ters “acceleration,
deceleration and positive/negative direction” can be parametrised
individually or grouped.
Acceleration:
Positive/negative direction
Setpoint value for acceleration to the speed setpoint value.
Deceleration:
Positive/negative direction
Setpoint value for deceleration to the speed setpoint value.
1) The parameter can only be parameterised in the Festo Configuration Tool (FCT) with activation of the control interface “ Analogue
input”.
