Voltage Input (Pr. 73) - Mitsubishi Electric FR-E540 K-EC Series Instruction Manual

Voltage input (Pr. 73)

4.2.28 Voltage input (Pr. 73)
Pr. 73 "0-5V/0-10V selection"
You can change the input (terminal 2) specifications in response to the frequency
setting voltage signal. When entering 0 to 10VDC, always make this setting.
Parameter Factory
Number Setting
73 0
Setting Terminal 2 Input Voltage
0 For 0 to 5VDC input (factory setting)
1 For 0 to 10VDC input
10 For 0 to 5VDC input
11 For 0 to 10VDC input
Note: 1. To change the maximum output frequency at the input of the maximum
frequency command voltage, use Pr. 38. 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.
2. When connecting a frequency setting potentiometer across terminals 10-2-5
for operation, always set "0" in this parameter.
Polarity reversible operation
By changing the input voltage, you can switch between forward rotation and reverse rotation.
Set "10" or "11" in Pr. 73 to make this function valid.
1) Set the output frequency using Pr. 902 "frequency setting voltage bias" and Pr. 903
"frequency setting voltage gain". The output frequency is 0Hz at the factory-set input
voltage of 2.5V (5V).
2) When Pr. 73 = "10" as factory-set, Pr. 902 = 2.5V. When Pr. 73 = "11", Pr. 902 = 5V.
Note: To calibrate the input voltage value at 0Hz, use Pr. 902 "frequency setting
voltage bias".
