FUNCTION C
ODES
< Function code configuration required for the inverter drive motor floating system and the
inverter drive motor fl commercial power-driven motor system >
(1) Function codes to be configured
Function code Name Data Description
J401 Pump control
mode selection
2: Inverter drive motor
floating system
3: Inverter drive motor
fl
commercial
power-driven motor
system
J101 to J138
J201 to J231 PID control 1
PID control 2 Depends on each code
setting These function codes configure PID control in
accordance with the system design.
PID1/PID2 switchable.
E20 to E27
o01 to o07 [Y1] to [Y5]
[30A/B/C]
[Y6] to [Y12]
88: AUX_L (Auxiliary
motor drive signal)
160 to 166:
M1_l to
M4_l (Motor 1 to 4
being driven by
inverter)
161 to 167:
M1_L to
M4_L (Motor 1 to 4
being driven by
commercial power)
These function codes assign inverter drive start
signals and commercial drive start signals to
the output terminals according to the number
of pumps.
For a maximum configuration, the optional
relay output card is required.
AUX_L is a drive signal for auxiliary pump.
J411 to J414 Motor 1 to
Motor 4 mode
selection
1: Enable These function codes configure motor modes
according to the number of pumps.
Only motors enabled can be control targets.
(2) Function codes recommended to be configured
Function code Name Data Description
J425 Motor
switching
procedure
1: Equal operating time This function code automatically adjusts the
start/stop sequence of commercial
power-driven pumps to equalize the operating
times of pumps.
(3) Function codes for individual adjustments
Configure the following function codes as needed.
Function code Name Data Description
J450 Motor increase
judgment
(Judgment
frequency)
0 to 120 Hz, Inherit
J451 Motor increase
judgment
(Duration time)
0.00 to 3600 s
This function code adjusts the motor adding
conditions.
If the frequency of the inverter-driven pump
exceeds the setting of J450 and keeps it for the
setting of J451, commercial power-driven
motor adding conditions are met.
The default is that if the frequency reaches the
setting of J118 (PID upper limiter), the adding
conditions are immediately met.
