Programming
3-10 Preset Reference
Option: Function:
3-02 Minimum Reference is set to -70
and 3-03 Maximum Reference is set to
50. In this case 0%=0 and 100%=70.
4-12 Motor Speed Low Limit
Range: Function:
0.0 Hz [0.0-400.0 Hz] Set the Minimum Motor Speed Limit
*
corresponding to the minimum output
frequency of the motor shaft.
NOTE
As the minimum output frequency
is an absolute value, it cannot be
deviated from.
4-14 Motor Speed High Limit
Range: Function:
65.0 Hz [0.0-400.0 Hz] Set the Maximum Motor Speed
*
corresponding to the maximum output
frequency of the motor shaft.
NOTE
As the maximum output frequency
is an absolute value, it cannot be
deviated from.
6-22 Terminal 60 Low Current
Range: Function:
This reference signal should
correspond to minimum reference
value set in 6-24 Terminal 60 Low
Ref./Feedb. Value.
0.14 mA [0.00-19.90 mA] Enter low current value.
*
CAUTION
The value must be set to min. 2 mA in order to activate
the Live Zero Timeout function in 6-01 Live Zero Timeout
Time.
6-23 Terminal 60 High Current
Range: Function:
This reference signal should
correspond to the high current
value set in 6-25 Terminal 60 High
Ref./Feedb. Value.
20.00 mA [0.10-20.00 mA] Enter high current value.
*
6-24 Terminal 60 Low Ref./Feedb. Value
Range: Function:
The scaling value corresponding to the
low current set in 6-22 Terminal 60 Low
Current.
0.000 [-4999-4999] Enter analog input scaling value.

MG02K202 - VLT is a registered Danfoss trademark
Function:
The scaling value corresponding to the
high current set in 6-23 Terminal 60 High
Current.
[-4999-4999] Enter analog input scaling value.
*
Function:
A first-order digital low pass filter time
constant for suppressing electrical noise
in terminal 60. A high time constant
value improves dampening, but also
increases time delay through the filter.
NOTE
This parameter cannot be changed
while motor runs.
[0.01-10.00 s] Enter time constant.
*
Function:
Select input to function as feedback
signal.
No Function
*
Analog Input 53
Analog Input 60
Pulse Input 33
Function:
Normal Feedback larger than setpoint result in a speed
*
reduction.
Feedback less than setpoint result in a speed
increase.
Inverse Feedback larger than setpoint result in a speed
increase.
Feedback less than setpoint result in a speed
reduction.
Function:
Disable Regulation of a given error will continue even
when the output frequency cannot be increased/
decreased.
Enable PI-controller ceases from regulating a given error
*
when the output frequency cannot be increased/
decreased.
Function:
[0.0-200.0 Hz] Until the set motor speed has been
*
reached the frequency converter
operates in Open Loop mode.
