TOEPC71061737D GA800 DRIVE INSTALLATION & PRIMARY OPERATION
Code
Name
Causes
Possible Solutions
There is loose wiring in the drive input power
terminals.
Tighten the terminal screws to the correct tightening torque.
There was a loss of power.
Use a better power supply.
The main circuit capacitors have become
unserviceable.
Examine the capacitor maintenance time in monitor
U4-05
[CapacitorMaintenance]
. If
U4-05
is more than 90%, replace the
control board or the drive. For information about replacing the
control board, contact Yaskawa or your nearest sales representative.
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.
Check the ambient temperature of the drive.
The Charge LED is broken.
Replace the control board or the entire 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.

Causes
Possible Solutions
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
.
oPE03
Multi-Function Input Setting Err
The settings for these parameters do not agree:
•
F3-10 to F3-25 [Terminal D1 to DF Function
Selection]
•
H1-01 to H1-08 [Terminals S1 to S8 Function
Selection]
•
H7-01 to H7-04 [Virtual Multi-Function Inputs 1
to 4]
Correct the parameter settings.
The settings for the standby mode function do not
agree:
•
b8-50 = 0 [Standby Mode Selection = Disabled]
and
H2-xx = 65 [MFDO Function Select =
Standby Output]
•
b8-50 = 1 [Enabled]
and
H2-xx ≠ 65
Correct the parameter settings.
The settings for MFDIs overlap.
Note:
This does not include
H1-xx = 20 to 2F [MFDI
Function Select = External Fault]
and
[Reserved]
.
Set the parameters correctly to prevent MFDI function overlap.
These pairs of MFDI functions are not set to Digital
Inputs (
H1-xx
,
F3-10 to F3-25
, and
H7-01 to H7-04
)
at the same time:
•
Setting values
10 [Up Command]
and
11 [Down
Command]
•
Setting values
75 [Up 2 Command]
and
76 [Down
2 Command]
•
Setting values
42 [Run Command (2-Wire
Sequence 2)]
and
43 [FWD/REV (2-Wire Sequence
2)]
Set the MFDI pairs.
