Parameter Range Default Function
1-73 Flying Start [0] Disabled
[1] Enabled
0
Select [1] Enable to enable the frequency
converter to catch a spinning motor. I.e. fan
applications. When PM is selected, Flying Start
is enabled.
3-02 Minimum Reference -4999-4999 0 The minimum reference is the lowest value
obtainable by summing all references
3-03 Maximum Reference -4999-4999 50 The maximum reference is the highest value
obtainable by summing all references
3-10 Preset Reference -100-100% 0 Enter the set point
3-41 Ramp 1 Ramp Up Time 0.05-3600.0 s Size related
Ramp up time from 0 to rated 1-23 Motor
Frequency if Asynchron motor is selected;
ramp up time from 0 to 1-25 Motor Nominal
Speed if PM motor is selected"
3-42 Ramp 1 Ramp Down Time 0.05-3600.0 s Size related
Ramp down time from rated 1-23 Motor
Frequency to 0 if Asynchron motor is selected;
ramp down time from 1-25 Motor Nominal
Speed to 0 if PM motor is selected
4-12 Motor Speed Low Limit [Hz] 0.0-400 Hz 0.0 Hz Enter the minimum limit for low speed
4-14 Motor Speed High Limit [Hz] 0-400 Hz 65 Hz Enter the minimum limit for high speed
4-19 Max Output Frequency 0-400 Size related Enter the maximum output frequency value
6-29 Terminal 54 mode [0] Current
[1] Voltage
1 Select if terminal 54 is used for current- or
voltage input
6-20 Terminal 54 Low Voltage 0-10 V 0.07 V Enter the voltage that corresponds to the low
reference value
6-21 Terminal 54 High Voltage 0-10 V 10 V Enter the voltage that corresponds to the low
high reference value
6-22 Terminal 54 Low Current 0-20 mA 4 Enter the current that corresponds to the high
reference value
6-23 Terminal 54 High Current 0-20 mA 20 Enter the current that corresponds to the high
reference value
6-24 Terminal 54 Low Ref./Feedb.
Value
-4999-4999 0 Enter the feedback value that corresponds to
the voltage or current set in 6-20 Terminal 54
Low Voltage/6-22 Terminal 54 Low Current
6-25 Terminal 54 High Ref./Feedb.
Value
-4999-4999 50 Enter the feedback value that corresponds to
the voltage or current set in 6-21 Terminal 54
High Voltage/6-23 Terminal 54 High Current
6-26 Terminal 54 Filter Time
Constant
0-10 s 0.01 Enter the filter time comstant
20-81 PI Normal/ Inverse Control [0] Normal
[1] Inverse
0
Select [0] Normal to set the process control to
increase the output speed when the process
error is positive. Select [1] Inverse to reduce
the output speed.
20-83 PI Start Speed [Hz] 0-200 Hz 0 Enter the motor speed to be attained as a
start signal for commencement of PI control
20-93 PI Proportional Gain 0-10 0.01 Enter the process controller proportional gain.
Quick control is obtained at high amplifi-
cation. However if amplification is too great,
the process may become unstable
20-94 PI Integral Time 0.1-999.0 s 999.0 s Enter the process controller integral time.
Obtain quick control through a short integral
time, though if the integral time is too short,
the process becomes unstable. An excessively
long integral time disables the integral action.
