When Pr.03-05 is set to 0, the analog output voltage is directly proportional to the output
frequency of the AC motor drive. With Pr.03-06 set to 100%, the Maximum Output Frequency
(Pr.01-00) of the AC motor drive corresponds to +10VDC on the AFM output.
Similarly, if Pr.03-05 is set to 1, the analog output voltage is directly proportional to the output
current of the AC drive. With Pr.03-06 set to 100%, then 2.5 times the rated current
corresponds to +10VDC on the AFM output.
NOTE
Any type of voltmeter can be used. If the meter reads full scale at a voltage less than 10 volts,
the parameter 03-06 should be set using the following formula:
Pr. 03-06 = ((meter full scale voltage)/10) x 100%
For Example: When using the meter with full scale of 5 volts, adjust Pr.03-06 to 50%. If
Pr.03-05 is set to 0, then 5VDC will correspond to Maximum Output Frequency.

Digital Output Multiplying Factor
Unit: 1
Settings
01 to 20 times
Factory Setting: 01
This parameter determines the multiplying factor for the AC drives digital output frequency at
the digital output terminals (DFM-DCM). The pulse frequency is equal to the AC motor drive
output frequency multiplied by Pr.03-07. (Pulse frequency = actual output frequency x Pr.03-07)

Terminal Count Value
Unit: 1
Settings
00 to 65500
Factory Setting: 00
This parameter sets the count value of the internal counter. The external terminal TRG
increases the internal counter. Upon completion of counting, the specified output terminal will
be activated. (Pr.03-00 to Pr.03-03 set to 14).
When the display shows c5555, the drive has counted 5,555 times. If display shows c5555
•
, it
means that real counter value is between 55,550 to 55,559.
