REMARKS
<When the fault could not be identified>
When the cause of the fault is not specified even after performing the operation mentioned
above, the current running frequency, output current and output voltage at the point are
displayed on the screen.
Press to display the estimated cause related.
First, the running frequency, output current and
output voltage of the inverter are displayed.
Press to display the estimated cause of
large output current.

Low Impedance
Motor?
Reduce TrqBst
Pr.0,46,112
The motor in use may be a special motor other
than the general-purpose 3-phase induction
motor. If so, reduce the torque boost setting.
Related parameters: Pr. 0, 46, 112
Low Trq
Motor?
Reduce TrqBst
Pr.0,46,112
The motor in use may be a constant-torque motor
(motor for inverter). If so, reduce the torque boost
setting. Related parameters: Pr. 0, 46, 112
Trq. Bst
Setting Err?
See Pr. 0, 46,
Since the torque boost setting may be
inappropriate, check the following relevant
parameters: Related parameters: Pr. 0, 46, 112
V/F Setting
Error?
See Pr. 3, 14,
Since the V/F pattern setting may be
inappropriate, check the following relevant
parameters: Related parameters: Pr. 3, 14, 19,
47, 113
Load Too Big?
OutPut
The load may be too heavy. An open phase may
have occurred between the inverter and motor.
Phase Loss?
