1104 EXT REF1 MIN
Sets the minimum frequency reference for external reference 1 in Hz. When analogue input signal is at
minimum, external reference 1 equals to
1105 EXT REF1 MAX
Sets the maximum frequency reference for external reference 1 in Hz. When analogue input signal is at
maximum, external reference 1 equals to
1106 EXT REF2 SELECT
This parameter selects the signal source for external reference 2. The alternatives are the same as with
external reference 1, see 1103
1107 EXT REF2 MIN
Sets the minimum reference in %. When analogue input signal is at minimum, external reference 2 equals
to 2 . See Figure 6.
EXT REF MIN
• If the PID Control macro is selected, this parameter sets the minimum process reference.
• If any other macro than PID is selected, this parameter sets the minimum frequency reference. This
value is given as a percentage of the maximum frequency.
1108 EXT REF2 MAX
Sets the maximum reference in %. When analogue input signal is at maximum, external reference 2 equals
to 2
EXT REF MAX
• If the PID Control macro is selected, this parameter sets the maximum process reference.
• If any other macro than PID Control is selected, this parameter sets the maximum frequency reference.
This value is given as percentage of maximum frequency.
1115 REF STEP SEL
Frequency reference modification selection.
0 =
NOT SEL
Reference modification is not used.
1 = 3 4
DI U D
Reference correction up is given to frequency reference, when digital input DI3 is activated and reference
correction down is given, when digital input DI4 is activated.
2 = 4 5
DI U D
Same as above except that digital inputs in use are DI4 and DI5.
1117 REF STEP MODE
0 =
FREQ STEP
Fixed frequency step is added to or subtracted from basic frequency reference. Frequency steps in Hz are
defined with parameters 1118
1 =
PERCENTAGE STEP
In this case frequency step is given as percentage of basic frequency reference. Parameters 1118
and 1119
UP REF STEP DOWN
1118 REF STEP UP
Frequency reference step up. Given as Hz or percentage depending on the value of parameter 1117
.
STEP MODE
1119 REF STEP DOWN
Frequency reference step down. Given as Hz or percentage depending on the value of parameter 1117
.
STEP MODE
1120 STEP DLY ON
Switch on delay for reference step.
1121 STEP DLY OFF
Switch off delay for reference step
