Y1: Application Basics
■
Y1-01: Multiplex Mode
No.
(Hex.)
Name Description
Default
(Range)
Y1-01
(3C00)
Multiplex Mode
Sets the base operation mode of the drive controller.
0
(0, 3)
0 : Drive Only
Designed for single pump stand-alone applications.
3 : Memobus Network
You can network maximum of four drives together for system redundancy and accurate control.
These functions will operate slightly different when Y1-01 = 3 :
• Start Level: Active on the first pump in the network. Drives that are staging or in alternation will not undergo this
process.
•
Sleep: Active when the drive is the only drive running on the network.
•
Pre-charge: Active only on the first drive to run in the network.
•
Low City Pressure: Active on any drive in the network. An alarm condition will cause other drives in the network to
stop running and show a
“ Network Drive Error ” “ Check Faulted Drive ” message.
• Utility Delay: When this function is active, the drive is unavailable to the HV600 MEMOBUS network and the
Home screen text will show
“
Idle: No AUTO Cmd
”
.
■
Y1-04: Sleep Wake-up Level
No.
(Hex.)
Name Description
Default
(Range)
Y1-04
(3C03)
RUN
Sleep Wake-up Level
Sets the level that feedback must be less than for the time set in Y1-05 [Sleep Wake-up Level Delay
Time] to start the system. This level also sets the wake up level when the drive is in Sleep Mode.
When Y1-04 < 0 , the feedback level must decrease this amount to less than the setpoint.
0.0
(-999.9 - +999.9)
Note:
• When PID operates in reverse mode, the feedback value must increase to more than the start level for the time set in Y1-05 for the system to
start.
•
When Y2-01 = 5 [Sleep Level Type = Output Frequency (non-PID)] , the drive will ignore this parameter.
•
When Y1-01 = 3 [Multiplex Mode = Memobus Network] , function is active only on the first drive in the network. Drives that are staging or
in alternation will not undergo this process.
• Set this parameter to 0.0 to disable the function.
•
Range is 0.00 to 99.99 with sign-bit
“
-
”
or
“
+
”
indicating Delta to Setpoint.
•
Display unit and scaling change when the system units change.
■
Y1-05: Sleep Wake-up Level Delay Time
No.
(Hex.)
Name Description
Default
(Range)
Y1-05
(3C04)
RUN
Sleep Wake-up Level Delay
Time
Sets the drive to start the System again when the feedback decreases to less than Y1-04 [Sleep Wake-
up Level] for the time set in this parameter.
1 s
(0 - 3600 s)
■
Y1-06: Minimum Speed
No.
(Hex.)
Name Description
Default
(Range)
Y1-06
(3C05)
RUN
Minimum Speed
Sets the minimum frequency at which the drive will run. The drive applies this setting to HAND and
AUTO modes.
0.0 Hz
