Multi-pump (M3.14)

The Multi-Pump functionality controls up to four motors (pumps or fans) with PID Controller 1. The drive is
connected to one motor which is the regulating motor. This motor connects and disconnects the other motors
to/from the mains using contactors controlled with relays when needed, to maintain the correct setpoint.
The Auto-Change function controls the order/priority in which the motors are started to guarantee their equal wear.
The controlling motor can be included in the Auto-Change and interlock logic, or it may be selected to always
function as Motor 1. Motors can be taken out of use momentarily (for example, for service). This is completed
using the interlock function.
The Multi-Pump settings are presented in the following table:

Description
Settings:
0 = Disabled
1 = Enabled
Upper actual/process value
supervision.
Lower actual/process value
supervision.
If the desired value is not reached
within this time, a fault or alarm is
created.
Description
Defines the total number of motors
to be used with the multi-pump
function.
Enables parameter for the interlock
function to be used with the multi-
pump function. Interlocks are used
to tell the system if a motor is
connected or not.
0 = Disabled
1 = Enabled
Defines if the motor connected to
the drive is included in the auto-
change function or not.
0 = Disabled (Not included)
1 = Enabled (included)
Disable/enable rotation of starting
order and priority of motors.
0 = Disabled
1 = Enabled
Defines the time between auto
change in accordance with
Autoch:FreqLim (P3.14.6) and
AutochMotorLimit (P3.14.7).
