Type
Description
Lost Keypad
Displayed when operating commands come from the keypad or there is any
problem with the communication between the keypad and inverter’s main body
in Keypad JOG mode after setting PRT-11 (Lost KPD Mode) to
“
0
”.
Set the Lost
Keypad (29) at OUT31-33.
Check Line PLZ
Displayed when there is any problem with communication between the keypad
and the iS7 Control CPU (control connection cables).
Fire Mode
Displayed when the fire function is activated. If a contact signal output is
required, set the Fire Mode (37) at OUT31-33.
PID Sleep
Displayed in PID Sleep mode. This warning is provided to distinguish the PID
Sleep mode from a stopped state.
AUX Power On
Displayed when the control power is supplied with the auxiliary power module.
If the auxiliary power module has been installed, an AUX Power On warning is
provided instead of a Low Voltage trip when the main power is turned off.

Troubleshooting Fault Trips
Type
Problem
Solution
Over Load
The load is greater than the motor
’
s
rated capacity.
Ensure that the motor and inverter have
appropriate capacity ratings.
The set value for the overload trip
level (PRT-21) is too low.
Increase the set value for the overload trip
level.
Under Load
There is a motor-load connection
problem.
Replace the motor and inverter with lower
capacity models.
The set value for the underload level
(PRT-29 and PRT-30) is less than the
system’s minimum
load.
Increase the set value for the underload
level.
Over
Current1
Acc/dec time is too short compared to
load inertia (GD2).
Increase acc/dec time.
The inverter load is greater than the
rated capacity.
Replace the inverter with a model that has
increased capacity.
The inverter supplied an output while
the motor was idling.
Operate the inverter after the motor has
stopped or use the speed search function
(CON-60).
