Operation and Software
122 BA8230
Window speed = 0
This parameter determines the band of tolerances within which drive standstill is
detected.
Speed zero detection controls the STOP function in the start-up interlock. In addition,
the monitor signal can be output through the field bus and, if configured accordingly,
through terminal :23/:24 (see parameter “D-Output 1 :23/:24").
If there is a change in the ratio between "Standard frequency" and "No. of pairs of
poles" the parameter setting is affected in proportion.
Adjustment range: (0,001...0,1) * "Standard frequency" * 60/No. of pairs of
poles
As supplied: 3 min
-1
Reference speed
With this parameter you can preset a speed comparison value at which, if exceeded,
the 8230 frequency inverter generates a signal.
The signal can be output through the field bus and, if configured accordingly, through
terminal :23/:24 (see parameter “D-Output 1 :23/:24").
If there is a change in the ratio between "Standard frequency" and "No. of pairs of
poles" the parameter setting is affected in proportion.
Adjustment range: 0 ... 2 * "Standard frequency" * 60/No. of pairs of poles
As supplied: 750 min
-1
Reference load current
With this parameter you can preset a comparison value for the load current (rotor
current XIL) at which, if exceeded, the 8230 frequency inverter generates a signal.
This signal can be output through the field bus and, if configured accordingly,
through :23/:24 (see parameter “D-Output 1 :23/:24”).
The reference value refers to the rated rotor current calculated from the motor type
data.
Adjustment range: 0 ... value corresponding to max. inverter current .
