How to Programme the Frequ...
6-52 Terminal 42 Output Max Scale
Range: Function:
100.00 [0.00 Scale for the maximum output (20 mA) of the
% - analog signal at terminal 42.
*
200.00 Set the value to be the percentage of the full
%] range of the variable selected in 6-50 Terminal 42
Output.
It is possible to get a value lower than 20 mA at
full scale by programming values >100% by
using a formula as follows:
mA desired maximum current
20 /

i e mA
. . 10 :
10
EXAMPLE 1:
Variable value= OUTPUT FREQUENCY, range = 0-100 Hz
Range needed for output = 0-50 Hz
Output signal 0 or 4 mA is needed at 0 Hz (0% of range) -
set 6-51 Terminal 42 Output Min Scale to 0%
Output signal 20 mA is needed at 50 Hz (50% of range) -
set 6-52 Terminal 42 Output Max Scale to 50%
EXAMPLE 2:
Variable= FEEDBACK, range= -200% to +200%
Range needed for output= 0-100%
Output signal 0 or 4 mA is needed at 0% (50% of range) -
set 6-51 Terminal 42 Output Min Scale to 50%
Output signal 20 mA is needed at 100% (75% of range) -
set 6-52 Terminal 42 Output Max Scale to 75%

EXAMPLE 3:
Variable value= REFERENCE, range= Min ref - Max ref
Range needed for output= Min ref (0%) - Max ref (100%),
0-10 mA
Output signal 0 or 4 mA is needed at Min ref - set
6-51 Terminal 42 Output Min Scale to 0%
Output signal 10 mA is needed at Max ref (100% of range)
- set 6-52 Terminal 42 Output Max Scale to 200%
(20 mA / 10 mA x 100%=200%).
14-01 Switching Frequency
Option: Function:
Select the inverter switching frequency. Changing
the switching frequency can help to reduce
acoustic noise from the motor.
NOTE
The output frequency value of the
frequency converter must never exceed 1/10
of the switching frequency. When the motor
is running, adjust the switching frequency in
14-01 Switching Frequency until the motor is
as noiseless as possible. See also
14-00 Switching Pattern and the section
Derating.
