P3.15.15 CONSTANT PRODUCTION SPEED (ID 1513)
Use this parameter to set the constant speed at which the motor locks when the next motor
starts in the Multimaster system.
The value of this parameter is given as a percentage of the minimum frequency to the
maximum frequency.
P3.15.16 RUNNING PUMPS LIMIT (ID 1187)
Use this parameter to set the maximum number of motors that run at the same time in the
Multi-pump system.
NOTE!
If the value of parameter P3.15.2 Number of Pumps changes, the same value
changes automatically to this parameter.
Example:
The Multi-pump system has 3 pumps, but only 2 pumps can operate at the same time. The
third pump is installed in the system for redundancy. The number of pumps that can operate
at the same time:
•
Running Pump Limit = 2
P3.15.17.1 PUMP 1 INTERLOCK (ID 426)
Use this parameter to select the digital input signal that is used as interlock signal for the
Multi-pump system.
When the Pump interlocking function (P3.15.5) is enabled, the drive reads the statuses of the
digital inputs of the pump interlock (feedback). When the input is CLOSED, the motor is
available for the Multi-pump system.
When the Pump interlocking function (P3.15.5) is disabled, the drive does not read the
statuses of the digital inputs of the pump interlock (feedback). The Multi-pump system sees
all pumps in the system as available.
•
In the Single drive mode, the digital input signal that is selected with this
parameter shows the interlock status of pump 1 in the Multi-pump system.
•
In the Multifollower and Multimaster modes, the digital input signal that is
selected with this parameter shows the interlock status of the pump that is
connected to this drive.
P3.15.17.2 PUMP 2 INTERLOCK (ID 427)
Use this parameter to select the digital input signal that is used as interlock signal for the
Multi-pump system.
P3.15.17.3 PUMP 3 INTERLOCK (ID 428)
Use this parameter to select the digital input signal that is used as interlock signal for the
Multi-pump system.
