Lenze 8600 series - Overlay of Position Controller

9.9.1 Overlay of Position controller
The function “overlay of position controller” is necessary for the
Start of the winding-up process with the dancer in an extreme
Position. The full effect of the dancer-Position controller could lead
to extreme operating conditions. Therefore the slow overlay of the
output Signal is necessary when starting the winding-up process.
The function “overlay of Position controller” tan be achieved via
freely assignable terminals, keypad, or the serial interface. The
“overlay of Position controller” is based on a ramp function
generator which controls the drive according to the acceleration
and deceleration time Cl 88 when activated. (The acceleration time
corresponds to the deceleration time).
The ramp function generator of the “overlay Position controller” is
reset after each controller inhibit. That means, when enabling the
controller again, the ramp function generator is accelerated
provided that the function “overlay Position controller” is activated.
For programming the freely assignable terminal, the terminal which
is to be assigned to the function “suppression of dancer-Position
controller” must be selected under code Cl 12. The function is set
under code Cl 13 and thus transmitted to the terminals selected
under Cl 12.
The modulation of the dancer-Position control tan be read under
Cl90 if the function “overlay Position controller” is activated. (unit
