Quick start
The quick start function aims to overcome the problems associated with the high
regulation gains that are necessary at start-up but inappropriate for regulation.
The drive accelerates linearly on a ramp (ACC) until its speed reaches the
configured quick start threshold (SFS).
Once it reaches this threshold (SFS), PID regulation begins.
Automatic restart on underload and overload faults
Generally, the user can set a parameter to activate automatic restarting after a fault,
if the cause(s) of the fault no longer exist(s).
In the case of underload and overload faults, a delay which can be set between 1 s
and 6 min 16 s can be used to delay the restart.
PID reference adjustment range for the end user
This function allows the end user to adjust the PID regulator reference to increase or
reduce the rate of flow.
Adjustment by the user is either by modifying the PID regulator reference parameter,
or by manual control of the navigation button, accessible on the drive's front panel.
The installer has access to two PID reference limit parameters, which can be used to
define a user's range of action.
Application functions can be assigned to the same logic input, in which case one
logic input enables a number of functions (for example, direction of operation and
ramp time switching).
A check must be carried out to ensure that the functions are compatible:
Direction of operation and 2-wire control: Forward operation can only be
assigned to LI1.
Direction of operation and 3-wire control: Forward operation can only be
assigned to LI2.
Automatic restart: This function requires the configuration of 2-wire level control.
Changing the control type configuration deactivates automatic restarting.
Automatic catching of a spinning load with speed detection: Incompatible with
continuous standstill DC injection. Configuring this function deactivates automatic
catching of a spinning load.
