Range: 0 to 1 (default setting: 0)
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 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.
The value 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.
