PoC
Cause
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).

R-DNE-So
Cause
Terminal So (H1-0o = 95) has been
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.).
Terminal So (H1-0o = 95) has been open
for the time set in P4-26, Remote Drive
Disable On-Delay, when P4-25, Remote
Drive Disable Selection, was set to 1
(N.C.).

rUn
Cause
A motor switch command was entered
during run.
HOA Keypad Display
SE
Cause
A digital input set to 67H (MEMOBUS/
Modbus test) was closed while the drive
was running.

Temperature Lost Geothermal Input
Cause
The input signal level has dropped below 3
mA or risen above 21 mA and b1-01 = 5,
H3-0o = 21 (Geothermal Input), H3-0o =
2 (4 to 20 mA), and Q2-09 = 1 (Alarm).
Parameter b1-01 = 5, H3-0o≠ 21
(Geothermal Temp), and Q2-09 = 1
(Alarm).
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, H3-0o = 21
(Geothermal Input), H3-0o = 2 (4 to 20
mA), and Q2-09 = 1 (Alarm).

YASKAWA TOEP YAIP1W 01A YASKAWA AC Drive - iQpump1000 Quick Start Guide
This verifies that the test was successful.
Pump Over Cycle
• 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.
Remote Drive Disable
Remove conditions causing the terminal to close.
Remove conditions causing the terminal to open.
Motor Switch during Run
A command to switch motors 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).
Stop the drive and run the test again.
Temperature Lost Geothermal Input
The geothermal input is not present.
Confirm that the device connected to the analog input terminal is installed and working properly.
Assign one of the analog inputs to "Geothermal Temperature", H3-0o = 21.
Confirm that the device connected to the analog input terminal is installed and working properly.
IGBT Maintenance Time (90%)
IGBTs have reached 90% of their expected performance life.
