Voltage Input (Pr. 73) - Mitsubishi Electric FR-A520-0.4K Instruction Manual

4.2.30 Voltage input (Pr. 73)

Pr. 73 "0-5V/0-10V selection"
You can select the analog input terminal specifications, the override function and the function to switch
between forward and reverse rotation depending on the input signal polarity.

Note: 1. The value of terminal 1 (frequency setting auxiliary input) is added to the main speed setting
signal of terminal 2 or 4.
2. When override has been selected, terminal 1 or 4 is for the main speed setting and terminal 2 is
for the override signal (50 to 150% at 0-5V or 0-10V). (If the main speed of terminal 1 or 4 is not
input, compensation made by terminal 2 is made invalid.)
3. Indicates that a negative-polarity frequency command signal is not accepted.
4. To change the maximum output frequency at the input of the maximum frequency command
voltage (current), use the frequency setting voltage (current) gain, Pr. 903 (Pr. 905). At this time,
the command voltage (current) need not be input. Also, the acceleration/deceleration time, which
is a slope up/down to the acceleration/deceleration reference frequency, is not affected by the
change in Pr. 73 setting.
5. When the Pr. 22 setting is "9999", the value of terminal 1 is for the stall prevention operation level
setting.
6. ∗ indicates the main speed setting.
