Description
100% =max. frequency (n011)
Bias value is stored in n048
when Up/Down 2 command is
completed.
n048 is limited by setting of
n171 and n172.
The setting of n048 has no
effect under following condi-
tions:
• Up/Down 2 function is not
selected (n056 <> 36)
• Frequency reference
method is changed (n004
setting)
• n100 is changed from 0 to 1
• n100=0 and Run signal is
OFF
• When n045= 0 and n047= 1
and S6/S7 are both set ON
or OFF
• Max. frequency (n011) is
changed
If analogue reference (or
pulse train) value change is
bigger than value of n049,
bias value is cleared.
The Up/Down 2 bias value is
limited by n171 (upper limit)
Limit is fixed to:
Fref + (Fmax x n171) / 100
The Up/Down 2 bias value is
limited by n172 (lower limit)
Limit is fixed to:
Fref - (Fmax x n172) / 100
Selects if bias value is saved
to EEPROM after RUN signal
is removed (frequency must
be hold for more than 5s).
0: not saved to EEPROM.
1: saved to EEPROM
Displays the frequency offset
caused by Up/Down com-
