PoC
Pump Over Cycle
Cause
Possible Solution
The pump has exceeded the number of
cycles set in P2-10 in the time set in P2-11
and P2-12 is set to 1 (alarm).
• Set the Pump Over Cycle alarm characteristics in P2-10 and P2-11.
• Drive response to this condition is controlled by P2-12, Over Cycling Mode.

closed for the time set in P4-26, Remote
Drive Disable On-Delay, when P4-25,
Remote Drive Disable Selection, was set to
0 (N.O.).
Remove conditions causing the terminal to close.

rUn
Motor Switch during Run
A command to switch motors was entered during run.
Cause
Possible Solution
A motor switch command was entered
during run.
Change the operation pattern so that the motor switch command is entered while the drive is stopped.

MEMOBUS/Modbus Communication Test Mode Error
Note:
This alarm will not trigger a multi-function output terminal that is set for alarm output
(H2-
oo
= 10).
Cause
Possible Solution
A digital input set to 67H (MEMOBUS/
Modbus test) was closed while the drive
was running.
Stop the drive and run the test again.

Temperature Lost Geothermal Input
Temperature Lost Geothermal Input
The geothermal input is not present.
Cause
Possible Solution
The input signal level has dropped below 3
mA or risen above 21 mA and b1-01 = 5,
H3-0
o
= 21 (Geothermal Input), H3-0
o
=
2 (4 to 20 mA), and Q2-09 = 1 (Alarm).
Confirm that the device connected to the analog input terminal is installed and working properly.
Parameter b1-01 = 5, H3-0
o
≠
21
(Geothermal Temp), and Q2-09 = 1
(Alarm).
Assign one of the analog inputs to “Geothermal Temperature”, H3-0
o
= 21.
The input signal level has dropped below 3
mA or risen above 21 mA when the drive
was in HAND Mode or had no Run
command and b1-01 = 5, H3-0
o
= 21
(Geothermal Input), H3-0
o
= 2 (4 to 20
mA), and Q2-09 = 1 (Alarm).
Confirm that the device connected to the analog input terminal is installed and working properly.
