Troubleshooting
105
IGBT over heat (oH1)
• IGBT temperature exceeds
protection level
• Ensure that the ambient temperature falls within the specified
temperature range.
• Make sure that the ventilation holes are not obstructed.
• Remove any foreign objects from the heatsinks and check for
possible dirty heat sink fans.
• Check the fan and clean it.
• Provide enough spacing for adequate ventilation.
InrCom Time Out (ictE)
• Internal communication time-out • Check Comm card installation
• Check communications settings
• Check wiring and grounding for possible interference
Internal BT (CardiBTc)
• Bluetooth card error
• Check card installation and [Comm-30] Comm Card ID
Lv at accel (LvA)
• DC BUS voltage is less than PROT-
03 during acceleration
• Check if the input voltage is normal
• Check for possible sudden load
• Adjust setting of PROT-03
Lv at decel (Lvd)
• DC BUS voltage is less than PROT-
03 during deceleration
• Check if the input voltage is normal
• Check for possible sudden load
• Adjust setting of PROT-03
Lv at normal SPD (Lvn)
• DC BUS voltage is less than PROT-
03 in constant speed
• Check if the input voltage is normal
• Check for possible sudden load
• Adjust setting of PROT-03
Lv at stop (LvS)
• DC BUS voltage is less than PROT-
03 at stop
• Check if the input voltage is normal
• Check for possible sudden load
• Adjust setting of PROT-03
MC Fault (ryF)
• Electromagnet switch error.
Electric valve switch error when
executing Soft Start. (Frame E
and above.)
• Do not disconnect RST when drive is still operating.
Motor overheat (oH3)
• The internal temperature of the
VFD exceeds the setting of PROT-
20 (PTC level) or PROT-31 (PT100
level 2).
• Make sure that the motor is not obstructed.
• Ensure that the ambient temperature falls within the specified
temperature range.
• Change to a higher power motor.
No Flow (NOFL)
• No water flow (pump application) • Refer to
“No Flow Protection” on page 78
.
oc at accel (ocA)
• Over current during acceleration.
Output current exceeds 2.4 rated
current during acceleration.
• Short-circuit at motor output: Check for possible poor insulation at
the output.
• Acceleration Time too short: Increase the Acceleration Time.
• VFD output power is too small for the application.
oc at decel (ocd)
• Over current during decelration.
Output current exceeds 2.4 rated
current during deceleration.
• Short-circuit at motor output: Check for possible poor insulation at
the output.
• Acceleration Time too short: Increase the Acceleration Time.
• VFD output power is too small for the application.
oc at normal SPD (ocn)
• Over current at normal speed.
Output current exceeds 2.4 rated
current during constant speed.
• Short-circuit at motor output: Check for possible poor insulation at
the output.
• Acceleration Time too short: Increase the Acceleration Time.
• VFD output power is too small for the application.
oc at stop (ocS)
• Over-current at stop. Hardware
failure in current detection
• Please call technical support.
oc HW error (Hd1)
• Over-current detection error
• Reboots the power. If fault code is still displayed on the keypad,
please call technical support.
occ HW error (Hd3)
• IGBT short-circuit detection when
power is ON
• Reboots the power. If fault code is still displayed on the keypad,
please call technical support.
Over load (OL)
• Overload
•
Fault
