ADVANCED
This function block is viewed in three
menus on the MMI and contains the
parameters for the advanced-user.
The ADVANCED MMI menu only
contains the I GAIN IN RAMP parameter.
ADAPTION
This MMI menu contains parameters for
speed loop gain scheduling.
ZERO SPD. QUENCH
Similar to Standstill logic (i.e. it stops
making current but keeps the contactor in) except that the speed loop remains enabled and will
cause the current loop to unquench very quickly.

Parameter Descriptions
MODE Range: 0 to 3
0 - Disabled
1 - Speed Feedback Dependent
2 - Speed Error Dependent
3 - Current Demand Dependent
SPD BRK 1 (LOW) Range: 0.00 to 100.00 %
IF MODE = 1 Then BRK-points correspond to speed feedback.
ELSE IF
MODE
= 2 Then
BRK-points
correspond to speed error.
ELSE IF
MODE
= 3 Then
BRK
-points correspond to current demand.
SPD BRK 2 (HIGH) Range: 0.00 to 100.00 %
Above SPD BRK 2 (HIGH) the normal gains (as per main menu above) prevail.
Between the two break-points, a linear variation of the gains is implemented.
PROP. GAIN Range: 0.00 to 200.00
Prop gain used below SPD BRK 1 (LOW)
INT. TIME CONST. Range: 0.001 to 30.000 SECS
Integral time constant used below SPD BRK 1 (LOW)
I GAIN IN RAMP Range: 0.0000 to 2.0000
While the RAMPING (Tag No. 113) flag is TRUE the integral gain is scaled by I GAIN IN
RAMP. This can be used to help prevent integral wind-up while the drive is ramping
(particularly high inertia loads).
