Parameter
Description
▪
Fixed Lag: This is a Lead/Lag control method with one PID-controlled Main drive and all of the Lag
drives operate at a fixed frequency. See parameter AP1-60, Lag Freq. Drives with this setting can
become a leader drive but must also have PID feedback connected. See
▪
Network Fbk: For Lag drives only. A method of operation for all Lag drives that operate in accordance
with the Lead (+) drive setting of Follow Lead or Fixed Lag. A drive with this setting cannot be a Lead
(+) drive and thus a feedback connection is not required.
AP1-41
Regular Bypass
•
For MMC (Contactor Lag) control only.
▪
Regular bypass mode is a function that disables the PI Control and drive/motor speed is based on
the feedback signal.
▪
Not used with Follow Lead, Fixed Lag or Network Feedback.
AP1-42 / MC2-07
* of Pumps
•
For MMC, (Contactor Lag)
▪
Sets the number of AUX Motors to operate with MMC
•
For Follow Lead, Fixed Lag
▪
Sets the total number of drives/pumps
connected
to the Lead/Lag system. This number may be
higher than the number of drives that are actually
operated
by lead/lag operation. See AP1-94 (* Of
Drives). If AP1-42 is set higher the AP1-94, the remaining drives become standby drives. Standby
drives can become part of the alternation sequence.
See
Section 17, Standby
•
For Network Fbk

The parameter is not used.
AP1-43 / MC2-18
Run Priority
⚫
For MMC (Contactor Lag)
◼
Set the motor number for the first priority motor. The priority will automatically change based on
the setting of the Alternation Sequence AP1-49 (ALT Sequence) during operation.
⚫
For Follow Lead, Fixed Lag, Network Fbk
◼
Set the Drive ID (based on COM-01) for the first priority. The priority will automatically change based
on the setting of the Alternation Sequence AP1-49 (ALT Sequence) during operation.
⚫
For Jockey Pumps, when AP1-88 (Jockey Pump) is set to “Yes”, and AP1-49 (ALT Sequence) is set to Op
Time Order, parameter setting is not possible.
AP1-44 / MC2-19
Lag Pump Run
(View Only)
⚫
For MMC (Contactor Lag)
◼
Displays the number of AUX motors in operation, excluding Main Motor.
⚫
For Follow Lead, Fixed Lag
◼
Displays the number of Lag drives/motors in operation, excluding Main drive.
AP1-45 / MC2-20
Curr Prty 1
AP1-46 / MC2-21
Curr. Prty 2
(View Only)
⚫
For MMC (Contactor Lag)
◼
Displays the run priorities of the motors operated by MMC.
⚫
For Follow Lead, Fixed Lag, Network Fbk
◼
Displays the run priorities of the drives operated by Lead/Lag.
⚫
Each digit represents the motor number (Drive ID), and the number displayed in each digit represents
priority.
⚫
Example: When 4321 is displayed, Motor 1 (Drive ID 1) priority is first, and Motor 2 (Drive ID 2) priority is
