(2) Explanation of control circuit terminal
Symbol
Terminal Name
Explanation of contents
L
Analogue power common
It is common terminal of frequency command signal (0, 02, 01) and analogue output, AM,
AMI. Don’t earth.
H Frequency
power
It is the DC+10V power for terminals.
Allowable load current
20mA
O
Frequency command
power terminal (voltage)
When inputting DC O - 10V, it is maximum frequency on 10V.
When maximum frequency is expected to be on being less
than 10V, set with A014.
Input Impedance 10k ohm
Allowable maximum
voltage 12V
O2
Frequency command
support (voltage)
When inputting DC O - +-10V, this signal is added to
frequency command of 0 or 0I terminal.
Input Impedance 10k ohm
Allowable maximum load
current 20mA
OI
Frequency command
Terminal (current)
When inputting DC4 - 20mA, 20mA is maximum frequency.
When only At terminal is ON, this input signal is effective.
