ramp set point
The internal reference value from the reference frequency channel and the reference
line value can be f
ed to the ramp individually or as an added variable. The operation
mode of the ramp function is set via the data set switchable parameter Ramp se

434.

-
Internal reference fre-
quency
The internal reference frequency is determined from
the percentage reference value source or the refer-
ence frequency channel.
2
-
Reference line value
The reference value is supplied externally via the
communication interface.
3
-
internal + reference line
value
Addition (considering the sign) of internal reference
frequency and reference line value
The Internal reference frequency can be controlled via the frequency inverter with the
control unit KP500 or the control software VPlus, the reference line value is supplied
via PZD2.
If Ramp setpoint 434 = 2 (reference line value only), this reference line value is lim-
ited to fmin.
The sign in front of
fmin with reference value = 0 is derived from the sign in front of
the last reference line value which was not 0.
After Mains On, the reference line value is limited to +fmin.
For Ramp setpoint 434 = 3, the sign of the total reference value results from the total
of internal reference frequency and reference line value.
