Setting
This parameter defines the bitwise status word for the multi-pump control
function.
Bit 00: ON/OFF1 (output to P0840)
Bit 01: Motor 1 switching on (output to P0731)
Bit 02: Motor 2 switching on (output to P0732)
Bit 03: Motor 3 switching on (output to P0733)
Bit 04: Motor 4 switching on (output to P0734)
Bit 05: Switching-in/-out operation in progress
Bit 06: No idle motor is running
Bit 07: OFF2 (output to P0845)
This parameter controls the execution of the multi-pump function.
0: Disable the multi-pump control function
1: Enable the multi-pump control function
Range: 0 to 1 (default setting: 1)
This parameter controls the selection mode for switching in/out motors
0: Fixed sequence (switching-in: M1, M2, M3, M4; switching-out: M4, M3,
M2, M1)
1: Absolute operating hours
Range: 0 to 1 (default setting: 0)
This parameter configures the total number of existing motors.
change to this parameter takes effect after the next time the script is started.
Range: 1 to 4 (default setting: 4)
Note: Before changing the value of P4013, change the value of P4002 to 0
first. After the value of P4013 is changed, re-power on the inverter.
The offset value is the threshold for switching out a motor. When actual
frequency r0021 < P1080 + P4014, the inverter will start to check whether
the switching out operation is necessary according to PID error r2273.
Default setting: 0
After the multi-pump function is enabled, when switching in/out motors, the
inverter first switches off the directly controlled motor by OFF2, and then
switches off the corresponding relay. This parameter is used to configure
the delay time between the two operations.
Default setting: 800
After the relay of the directly controlled motor is switched off, the inverter
switches on the relay of the motor to be controlled. This parameter is used
to configure the delay time between the two operations.
Default setting: 1500
After the relay of the motor to be controlled is switched on, the inverter
switches on the motor to be controlled by ON/OFF1. This parameter is
used to configure the delay time between the two operations.
Default setting: 1500
The motor cycling function will be triggered if the continuous operating
hours of a motor exceed the threshold. This parameter is used to config-
ure the threshold value.
Default setting: 24 (minimum value: 0.1)
Absolute operating hours timer for motor 1. It will be cleared after re-power
on.
