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.
Function:
corresponding to the minimum output
frequency of the motor shaft.
NOTICE
As the minimum output frequency
is an absolute value, it cannot be
deviated from.
Function:
corresponding to the maximum output
frequency of the motor shaft.
NOTICE
As the maximum output
frequency is an absolute value, it
cannot be deviated from.
Function:
This reference signal should
correspond to minimum reference
value set in 6-24 Terminal 60 Low
Ref./Feedb. Value.
Function:
This reference signal should
correspond to the high current
value set in 6-25 Terminal 60 High
Ref./Feedb. Value.
Function:
The scaling value corresponding to the
low current set in 6-22 Terminal 60 Low
Current.
6-25 Terminal 60 High Ref./Feedb. Value
Range:
50.00
[-4999-4999] Enter analog input scaling value.

6-26 Terminal 60 Filter Time Constant
Range:
0.01 s
[0.01-10.00 s] Enter time constant.

Inverse Feedback larger than setpoint results in a speed
increase.
Feedback less than setpoint results in a speed
reduction.
7-31 Process PI Anti Windup
Option:
Function:
[0]
Disable Regulation of a given error continues even when
the output frequency cannot be increased/
decreased.
[1]
Enable PI-controller ceases from regulating a given error

MG02K302 - Rev. 2013-12-03
Function:
The scaling value corresponding to the
high current set in 6-23 Terminal 60 High
Current.
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.
NOTICE
This parameter cannot be changed
while motor runs.
Function:
Select input to function as feedback
signal.
Function:
reached, the frequency converter
operates in open loop mode.
