Function:
This parameter chooses the active resulting reference. If Hand/Auto
linked reference is selected, the resulting reference will depend on
whether the drive is in Hand or Auto mode.
The table below shows which reference is active when Hand/Auto
linked reference , Remote reference or Local reference has been
selected. The Hand mode or Auto mode can be selected via the
keypad or by a digital input set in parameters 300 through 307 Digital
Inputs.
Reference Handling Hand Mode Auto Mode
Hand/Auto Local ref. active Remote ref. active
Remote Remote ref. active Remote ref. active
Local Local ref. active Local ref. active
Description of choice:
If Hand/Auto linked reference is chosen, the motor speed in Hand
mode will be set by the local reference, while in Auto mode it is set by
the remote references and any setpoints selected.
If Remote reference is selected, the motor speed will depend on
remote references and any setpoints selected, regardless of whether
Hand mode or Auto mode has been chosen.
If Local reference is selected, the motor speed will only depend on the
local reference set via the control panel, regardless of whether Hand
mode or Auto mode has been selected.
204 Minimum Reference (MIN. REFERENCE)
Value:
If parameter 100, Configuration = Open loop,
0.000Hz to parameter 205, Maximum Reference. ✭ 0.000 Hz
If parameter 100 Configuration = Closed loop,
parameter 413, Minimum Feedback, to
parameter 205, Maximum Reference. ✭ 0.000 Hz
Function:
The Minimum Reference sets the minimum value of the sum of all
references. If Closed loop has been selected in parameter 100,
Configuration , the minimum reference is limited by parameter 413,
Minimum Feedback .
Minimum reference is ignored when the local reference is active. In this
case, minimum reference is determined by parameter 201, Minimum
Frequency .
NOTE
For fan applications, factory setting of
parameter 204 is 6 Hz. For pump applications,
factory setting for parameter 204 is 18 Hz.
The unit for the reference can be seen from the following table:
Unit
Parameter 100 Configuration = Open loop Hz
Parameter 100 Configuration = Closed loop Par. 415
Description of choice:
Minimum Reference is the lowest reference value that can be set for
the drive.
205 Maximum Reference (MAX. REFERENCE)
Value:
If parameter 100, Configuration = Open loop,
parameter 204, Minimum Reference ,
to 1000.000 Hz ✭ 60.000 Hz
If parameter 100, Configuration = Closed loop,
parameter 204, Minimum Reference , to
parameter 414, Maximum Feedback . ✭ 60.000 Hz
Function:
The Maximum Reference sets the maximum value of the sum of all
references. If Closed loop has been selected in parameter 100,
Configuration , the maximum reference cannot be set above parameter
414, Maximum Feedback. The Maximum Reference is ignored when
the local reference is active.
The reference unit can be determined from the following table:
Unit
Parameter 100 Configuration = Open loop Hz
Parameter 100 Configuration = Closed loop Par. 415
Description of choice:
Maximum reference is the highest reference value that can be set for
the drive.
