FUNCTION C
ODES
Data for E61,
E62, or E63
Input assigned to [12],
[C1] and [V2]:
Description
44
External PID process
command 2
Inputs the 2nd command sources such as temperature
and pressure under external PID control 2 or 3.
Function code setting also required: J602/J652
45
External PID feedback
value 2
Inputs the 2nd feedback amounts such as temperature
and pressure under external PID control 2 or 3.
Under external PID control 1, external PID feedback
value 1 and addition, difference, average, maximum
and minimum can be calculated.
46
External PID manual
command 2
To be used for setting PID output (MV) manually
when external PID control 2 is canceled.
47
External PID process
command 3
Inputs the 3rd command sources such as temperature
and pressure under external PID control 3. Function
code setting also required: J652
48
External PID feedback
value 3
Inputs the 3rd feedback amounts such as temperature
and pressure under external PID control 3.
49
External PID manual
command 3
To be used for setting PID output (MV) manually
when external PID control 3 is canceled.
If these terminals have been set up to have the same data, the operation priority is
given in the following order:
E61 > E62 > E63
E64 Saving of Digital Reference Frequency
E64 specifies how to save the reference frequency specified in digital formats by the /
/ / keys on the keypad as shown below.
Data for E64 Function
0
Auto saving when the main power is turned OFF
The reference frequency will be automatically saved when the main power is
turned OFF. At the next power-on, the reference frequency at the time of the
previous power-off applies.
1
Saving by pressing key
Pressing the key saves the reference frequency. If the control power is
turned OFF without pressing the key, the data will be lost. At the next
power-ON, the inverter uses the reference frequency saved when the
key
was pressed last.
