Parameter Setting value / Description / Note Parameter set Available with option
P429 Fixed frequency 1 P
BSC STD MLT
BUS
-400 ... 400 Hz
[ 0 ] Following actuation via a digital input and enabling of the FI (right or left), the fixed frequency is used
as a setpoint.
A negative setting value will cause a direction change (based on the enabled direction of rotation P420
– P425, P470).
If several fixed frequencies are actuated at the same time, then the individual values are added with
the correct sign. This also applies to combinations with the jog frequency (P113), analog setpoint
(if P400 = 1) or minimum frequency (P104).
The frequency limits (P104 = f
min
, P105 = f
max
) cannot be over or undershot.
If none of the digital inputs are programmed for enable (right or left), the simple fixed frequency signal
results in an enable. A positive fixed frequency corresponds to a right enable, a negative to a left
enable.
