5.1.2 Basic parameter
P100 Parameter set S
Setting range
0 … 3
Factory setting { 0 }
Description
Selection of the parameters sets to be parameterised. 4 parameter sets are available.
The parameters to which different values can also be assigned in the 4 parameter
sets are known as "parameter set-dependent" and are indicated with a "P" in the
header in the following descriptions.
The operating parameter set is selected via correspondingly parametrised digital
inputs or BUS actuation.
If enabling is via the keyboard, the operating parameter set corresponds to the
settings in P100.
P101 Copy parameter set S
Setting range 0 … 4
Factory setting
{ 0 }
Description
"Copy parameter set". By confirmation with the OK key, the active parameter set (set
in P100) is copied into the selected parameter set.
Setting values
Value Meaning
0 Do not copy No copy process triggered.
1 Copy actual to P1
Copies the active parameter set to parameter set 1
2 Copy actual to P2
Copies the active parameter set to parameter set 2
3
Copy actual to P3
Copies the active parameter set to parameter set 3
4 Copy actual to P4
Copies the active parameter set to parameter set 4
P102 Acceleration time P
Setting range
0.00 … 320.00 s
Factory setting { 2.00 }
Description
The acceleration time is the time corresponding to the linear frequency increase from
0 Hz to the set maximum frequency P105. If an actual setpoint of <100 % is being
used, the acceleration time is reduced linearly according to the setpoint which has
been set.
The acceleration time can be extended by certain circumstances, e.g. FI overload,
setpoint delay, ramp smoothing, or if the current limit is reached.
Note
Care must be taken that the parameter values are realistic. A setting of P102 = 0 is
not permissible for drive units!
Ramp gradient:
Amongst other things, the ramp gradient is governed by the inertia of the rotor. A ramp
with a gradient which is too steep may result in the "breakdown" of the motor.
Extremely steep ramps (e.g.: 0 – 50 Hz in < 0.1 s) should be avoided, as this may
cause damage to the frequency inverter.
