TOEPC7106170YB YASKAWA AC Drive GA500 Installation & Primary Operation
Code
Name
Causes
Possible Solutions
The drive input power
transformer is too small and
voltage drops when the power is
switched on.
•
Check for an alarm when a molded-
case circuit breaker, Leakage Breaker
(ELCB, GFCI, or RCM/RCD) (with
overcurrent protective function), or
magnetic contactor is ON.
•
Check the capacity of the drive power
supply transformer.
Air inside the drive is too hot.
Measure the ambient temperature of the
drive.
The Charge LED is broken.
Replace the board or the drive. For
information about replacing the control
board, contact Yaskawa or your nearest
sales representative.

Parameter Setting Errors
Parameter setting errors occur when multiple parameter settings do not agree, or when
parameter setting values are not correct. Refer to the table in this section, examine the
parameter setting that caused the error, and remove the cause of the error. You must first
correct the parameter setting errors before you can operate the drive. The drive will not
send notification signals for the faults and alarms when these parameter setting errors
occur.

oPE01
Drive Capacity
Setting Error
The value set in
o2-04 [Drive
Model (KVA) Selection]
does
not agree with the drive model.
Set
o2-04
to the correct value.
oPE02
Parameter Range
Setting Error
Parameter settings are not in the
applicable setting range.
1.
Push
to show
U1-18 [oPE
Fault Parameter]
, and find
parameters that are not in the
applicable setting range.
2.
Correct the parameter settings.
Note:
•
If more than one error occurs at the
same time, other
oPExx
errors have
priority over
oPE02
.
Set
E2-01 ≤ E2-03 [Motor
Rated Current (FLA) ≤ Motor
No-Load Current]
.
Make sure that
E2-01 > E2-03
.
Note:
If it is necessary to set
E2-01 < E2-
03
, first lower the value set in
E2-03
,
and then set
E2-01
.
