OL-2 (OL-2)
• Overload
•
ov at accel (ovA)
• DC BUS over-voltage during
acceleration (230V: 410VDC;
460V: 820VDC; 575V: 1116VDC;
690V: 1318VDC).
• Check if the input voltage falls within the rated VFD input voltage
range.
• Check for possible voltage transients.
• If DC BUS over-voltage is due to regenerative voltage, increase the
acceleration time or add an optional brake resistor.
ov at decel (ovd)
• DC BUS over-voltage during
deceleration (230V: 410VDC;
460V: 820VDC; 575V: 1116VDC;
690V: 1318VDC).
• Check if the input voltage falls within the rated VFD input voltage
range.
• Check for possible voltage transients.
• If DC BUS over-voltage is due to regenerative voltage, please
increase the Deceleration Time or add an optional brake resistor.
ov at normal SPD (ovn)
• DC BUS over-voltage at constant
speed (230V: 410VDC; 460V:
820VDC; 575V: 1116VDC; 690V:
1318VDC).
• Check if the input voltage falls within the rated VFD input voltage
range.
• Check for possible voltage transients.
• If DC BUS over-voltage is due to regenerative voltage, please
increase the Deceleration Time or add an optional brake resistor.
ov at stop (ovS)
• Over-voltage at stop
• Check if the input voltage falls within the rated VFD input voltage
range.
• Check for possible voltage transients.
ov HW error (Hd2)
• Hardware failure in voltage
detection
• Reboots the power. If fault code is still displayed on the keypad,
please call technical support.
Over slip error (oSL)
• Slip exceeds Motor-19 setting and
time exceeds Motor-20 setting.
• Check if motor parameter is correct (please decrease the load if
overload
• Check the settings of Motor-19 and Motor-20.
Over-torque 1 (ot1)
• Current exceeds detection
criteria.
• Check whether the motor is overloaded.
• Check whether motor rated current setting (SET-03) is suitable.
Over-torque 2 (ot2)
• Current exceeds detection
criteria.
• Check whether the motor is overloaded.
• Check whether motor rated current setting (SET-03) is suitable.
Overpressure (OPRS)
• Overpressure
•
Password error (Pcod)
• Password is locked.
• Power off and restart the driver before entering the correct password
PC err address (CE2)
• Illegal data address
• Check if the communication address is correct
PC err command (CE1)
• Communication command is
illegal
•
PC err data (CE3)
• Illegal data value
•
PC slave fault (CE4)
• Data is written to read-only
address
• Check if the communication address is correct
PC time-out (CE10)
• Modbus transmission time-out
•
Phase lacked (OrP)
• Phase Loss protection
• Check that all 3 input phases are connected without loose contacts.
• For models 40hp and above, please check if the AC input circuit fuse.
PID Fbk error (AFE)
• PID loss (ACI)
• Check the wiring of the PID feedback
• Check the PID parameters settings
Rotor Pos Error (RoPd)
• Initial rotor position detection
error
•
S1-emergy stop (S1)
• Emergency stop for external
safety
•
Short-circuit (occ)
• Short-circuit is detected between
upper bridge and lower bridge of
the IGBT module
• Please call technical support.
Shutdown (SHDN)
•
•
STO (STO)
• Safe Torque Off function active
•
Fault
