OPE08
Terminal
Selection Parameter error. A parameter has
been changed that is not available in the present
control method. Example: H1-08=72 (Zero
Servo Command) is set while the drive is in
Flux Vector Control (A1-02=3), then the
Control Method is changed to Open Loop
Vector (A1-02=2).
1. Undo the last parameter change (if known)
2. Scroll through modified constants for obvious
setting errors.
3. Perform a user initialize (A1-05=1110)
CAUTION: All settings will be restored to
the factory defaults.
OPE10
V/F Ptrn Setting
V/F Parameter Setting Error. 1. Check Parameters E1-04 to E1-11.
OPE11
Carrier Frq/On-Delay
Carrier Frequency Parameter Error. 1. Check Parameters D10-01 to D10-05.
OPE18
Weight Measure
C10-05 or C10-06 Setting Error. 1. Satisfy condition C10-05 > C10-06
OPE19
Stp-Mthd & Ctrl
Incompatible Setting of Stopping Method
and Control Method. 1. Satisfy B3-03 > 6 and A1-02 < 1.
OPE21
2 Channel Missing
Option Card PG-Z2 or PG-W2 is missing
when C11-08 is Enabled. 1. Install correct option card.
OPE22
Ctrl & Motion
Incompatible Setting of Motion and Control
Mode. 1. Satisfy A1-02 < 1 and A1-03 > 2.
OPE23
Load Check
Load Check setting error. 1. Check C5-04 < C5-07 < C5-09.
OPE24
Slack Cable
Slack Cable setting error. 1. Check C11-04<C11-06 and C11-05>C5-07.
OPR
Oper Disconnect
Keypad Disconnected. The keypad is removed
while the inverter is running, and the run
command was initiated via the keypad RUN
key.
1. Secure the keypad.
2. Verify O2-06 setting.
OS-1, OS-2
Over Speed
Overspeed Fault. The motor has exceeded the
programmed detection level and time. This is
typically caused by an overshoot condition due
to an over-responsive ASR loop. If the drive is
programmed to flux vector “torque control”
mode, and no load is present, an overspeed fault
will typically occur.
1. Check the Automatic Speed Regulator
settings, D4 sub group.
2. Check setting of F1-08, F1-09.
3. Verify proper encoder PPR setting, F1-01.
OV
DC Bus Overvolt
Overvoltage Fault. The main circuit direct
current voltage exceeded the overvoltage level.
Detection level:
230V class—approx. 400V
460V class—approx. 800V
1. Extend the deceleration time.
2. Check for proper DBU operation.
3. Check the resistor.
4. Check the line voltage.
OV
(flashing
)
DC Bus Overvolt
Overvoltage Fault. Overvoltage occurs during
stop. Main circuit DC voltage rises above the
detection level while the drive output is off.
Detection level: 410V or more for 230V, 820V
or more for 460V.
1. Check the line voltage.
PF
Input Pha Loss
Input Phase Loss Fault. Inverter input power
supply has open phase.
1. Check the line voltage and fuses.
2. Remove power.
3. Retighten the input terminal screws.
PGO-1
PG Open Ch1
Pulse Generator Channel 1 Fault.
PGO-1-S, software detected fault.
PGO-1-H, hardware detected fault
1. Check for proper direction of encoder
feedback.
2. Please reference troubleshooting encoder
related faults on page 6-12.
