P17.8 545 Undervoltage Bypass Enable 2, 3, 4 RW
This parameter specifies whether an automatic switch to bypass will occur after the
undervoltage fault auto-restart tries have been exceeded.
0 Auto bypass on undervoltage fault tries exceeded disabled
1 Auto bypass on undervoltage fault tries exceeded enabled
P17.9 549 Overvoltage Bypass Enable 2, 3, 4 RW
This parameter specifies whether an automatic switch to bypass will occur after the
overvoltage fault auto-restart tries have been exceeded.
0 Auto bypass on overvoltage fault tries exceeded disabled
1 Auto bypass on overvoltage fault tries exceeded enabled
P18.1 342 Number of Motors 2, 3, 4 RW
Total auxiliary number of motors/pumps used with the Multi-Pump System.
P18.2 343 Bandwidth 2, 3, 4 RW
Percentage of the setpoint defining when motor connection or removal will not take
place.
P18.3 344 Bandwidth Delay 2, 3, 4 RW
With feedback outside the bandwidth, this time must pass before pumps are added
or removed.
P18.4 350 Interlock Enable 2, 3, 4 RW
Input tells the frequency converter if a motor/pump is connected or not.
P18.5 346 Include Freq Converter 2, 3, 4 RW
Input tells the drive if the motor/pump contacted with frequency converter is
included in the auto change and interlock system.
P18.6 345 Auto Change Enable 2, 3, 4 RW
Autochange will rotate the starting order/priority of the motors in the system to get
equal run time on all the motors.
P18.7 347 AutoChange Interval 2, 3, 4 RW
Defines how often to rotate starting order of motors/pumps.
P18.8 349 AutoChange Freq Limit 2, 3, 4 RW
An autochange is done when the autochange interval has elapsed and the drive is
running below autochange frequency limit.
P18.9 348 AutoChange Motor Limit 2, 3, 4 RW
An auto change is done when the auto change interval has elapsed and the number
of running aux motors is less than auto change motor limit.
