VACON® 100 FLOW
Application Guide
Use this parameter to set the rate of change in the motor potentiometer reference when it is increased or decreased.
The parameter value is entered as Hz/second.
11.5.3.4 (ID 367) Motor Potentiometer Reset
Location in the menu: P3.3.4.4
Use this parameter to set the logic for the resetting of the frequency reference of the motor potentiometer.
This parameter defines when the reference of the motor potentiometer is set to 0. There are 3 selections in the reset function: no
reset, reset when the drive stops, or reset when the drive is powered down.
Selection Selection name
number
0 No reset
1 Stop state
2 Powered down

11.5.4 Flushing Parameters

Use the Flushing function to override the normal control momentarily. Use the function to flush the pipeline or operate the pump
manually at the preset constant speed, for example.
The Flushing function starts the drive at a selected reference without a start command no matter the control place.
11.5.4.1 (ID 530) Flushing Reference Activation
Location in the menu: P3.3.6.1
Use this parameter to select the digital input signal that activates the Flushing function. The flushing frequency reference is bidirec-
tional and a reverse command does not affect the direction of the flushing reference.
When the digital input is activated, the drive starts.
11.5.4.2 (ID 1239) Flushing Reference
Location in the menu: P3.3.6.2
Use this parameter to set the frequency reference of the drive when the Flushing function is used.
The reference is bidirectional and a reverse command does not affect the direction of the flushing reference. The reference for the
forward direction is specified as a positive value and the reverse direction is specified as a negative value.

11.6 Ramps and Brakes Setup

11.6.1 Ramp 1

11.6.1.1 (ID 500) Ramp 1 Shape
Location in the menu: P3.4.1.1
Use this parameter to make the start and the end of the acceleration and deceleration ramps smoother.
With the parameters Ramp 1 Shape and Ramp 2 Shape, it is possible to make smoother the start and the end of the acceleration and
deceleration ramps. The value is set to 0.0% gives a linear ramp shape. The acceleration and deceleration act immediately to the
changes in the reference signal.
The value set between 1.0% and 100.0% gives an S-shaped acceleration or deceleration ramp. Use this function to reduce mechani-
cal erosion of the parts and current spikes when the reference changes. The acceleration time can be modified with parameters
P3.4.1.2 (Acceleration Time 1) and P3.4.1.3 (Deceleration Time 1).

Description
The last motor potentiometer frequency reference is kept through the stop state and kept in
memory when a power-down occurs.
The motor potentiometer frequency reference is set to 0 when the drive goes to the stop state,
or when the drive is powered down.
The motor potentiometer frequency reference is set to 0 only when a power-down occurs.
