Frt [F Ramp 2 threshold] 0 to 599 Hz 0 Hz
Ramp switching threshold.
Switching the 2nd Ramp when Frt is not equal to 0 (a value of 0 corresponds to the non-active function) and the output frequency exceeds Frt .
The switchover of the ramp by the threshold can be used together with the switchover [switch ramp] (rPS) as follows:
LI or bit Frequency Ramp
0 < Frt ACC , dEC
0 > Frt AC2 , dE2
1 < Frt AC2 , dE2
1 > Frt AC2 , dE2
rPS [Switch ramp] [No] (nO)
nO [No] (nO) : Not active
LI1 [LI1] (LI1)
- .
- .
- .
[...] (...) : See the assignment conditions
• ACC and dEC are activated if the assigned input or bit is at 0.
• AC2 and dE2 are activated if the assigned input or bit is at 1.
AC2 [Acceleration 2]
1)
0.01 to 6000 s
2)
5 s
Time for the acceleration from 0 to [rated motor frequency] (FrS) .
Make sure that this value is compatible with the frequency inverter's moment of inertia.
The parameter is accessible if [F thresh ramp 2] (Frt) >0 or [Switch ramp] (rPS) is assigned.
dE2 [Deceleration 2]
1)
0.01 to 6000 s
2)
5 s
Time for the deceleration of the [rated motor frequency] (FrS) until 0. Make sure that this value is compatible with the frequency inverter's
moment of inertia.
The parameter is accessible if [F thresh ramp 2] (Frt) >0 or [Switch ramp] (rPS) is assigned.
1) This parameter can also be accessed via the [SETTINGS] (SEt-) menu.
2) Range 0.01 to 99.99 s or 0.1 to 999.9 s or 1 to 9999 s in accordance with [ramp increment] (Inr) .
Parameter that can be modified during operation or when stopped.
Code Name/Description Factory settings
brA [Dec ramp adapt.] [Yes] (YES)
Activating this function automatically adapts the deceleration ramp, if this has been set at too low a value with respect to the inertia of the load,
which can cause an overvoltage fault.
nO [No] (nO) : Function not active.
YES
[Yes]
(YES) : Function active, for applications that do not require high deceleration time.
Depending on the size of the inverter and [motor control type] (CTT) , the following parameters with which a higher deceleration time can be
achieved than with the parameter [Yes] are displayed. Use comparative testing to determine your selection.
If [adj. decel ramp] (brA) is configured to [brake mot x] (dYnx) , the dynamic powers for brakes are improved by adding a current flow component.
The aim is to increase the iron loss and magnetic energy stored in the motor.
dYnA [brake mot A] (dYnA) : Addition of a constant current flow component.
dYnb [brake mot B] (dYnb) : Addition of a constant current flow component, with 100 Hz oscillating.
dYnC [brake mot C] (dYnC) : Addition of a constant current flow component, with 200 Hz oscillating but higher amplitude.
[Adj decel ramp] (brA) is forced to [No] (nO) if brake controller [BRAKE LOGIC] (bLC) is assigned and if [Control Braking perf.] (bbA) = [Yes]
(YES) . The factory setting for certain models becomes [Brake Mot A] (dYnA) if [Sine wave filter] (OFI) = [Yes] (YES) .
The function is incompatible with applications requiring:
• Positioning on a ramp
• Use of a braking resistor (this would not preserve its function)
The function does not apply if the parameter DCF = 0 is set.
