You can select a scaling range for the frequency reference from control place B between the Minimum and Maximum frequency.
If no scaling is desired set the parameter value to 0.
In
, input AI1 with signal range 0–100% is selected for Place B reference.
This scaling does not affect the fieldbus reference (scaled between Minimum frequency (parameter
ID 101
) and Maximum frequency
(parameter
ID 102
).

10.104 (ID 346) Output Frequency Limit 2 Supervision Function
Location in the menu:
P2.3.12
(Local/Remote Control Application, Multi-Step Speed Control Application, PID Control Application)
P2.3.4.3
(Multi-Purpose Control Application)
P2.3.2.3
(Pump and Fan Control Application)
Use this parameter to select the limit supervision function for the output frequency.
If the output frequency goes under/over the set limit (
ID 347
), this function generates a warning message through a digital output
depending on:
the settings of parameters
ID 312
to
ID 314
(Local/Remote Control Application, Multi-Step Speed Control Application, PID Con-
trol Application), or
to which output the supervision signal 2 (
ID 448
) is connected (Multi-Purpose Control Application, Pump and Fan Control Appli-
cation).
Brake control (only in Multi-Purpose Control Application) uses different output functions. See parameters
ID 445
&
ID 446
and
External Brake Control with Additional Limits (IDs 315, 316, 346–349, 352, 353)
10.105 (ID 347) Output Frequency Limit 2 Supervision Value
Location in the menu:
P2.3.13
(Local/Remote Control Application, Multi-Step Speed Control Application, PID Control Application)
P2.3.4.4
(Multi-Purpose Control Application)
P2.3.2.4
(Pump and Fan Control Application)
Use this parameter to set the limit supervision value for the output frequency when activating the limit supervision function.
Selects the frequency value supervised by parameter ID 346. See
10.106 (ID 348) Torque Limit, Supervision Function
