Descriptions
ocS
Oc at stop
Fault
Over-current at stop
Corrective Actions:
Return to the factory
GFF
Ground fault
Fault
Corrective Actions:
When (one of) the output terminal(s) is grounded, short circuit current is
more than 75% of AC motor drive rated current, the AC motor drive power
module may be damaged.
NOTE: The short circuit protection is provided for AC motor drive
protection, not for protection of the user.
1. Check the wiring connections between the AC motor drive and motor
for possible short circuits, also to ground.
2. Check whether the IGBT power module is damaged.
3. Check for possible poor insulation at the output line.
occ
Short Circuit
Fault
Short-circuit is detected between upper bridge and lower bridge of
the IGBT module.
Corrective Actions:
Return to the factory
ovA
Ov at accel
Fault
DC BUS over-voltage during acceleration
(230V: DC 450V; 460V: DC 900V)
Corrective Actions:
1. Check if the input voltage falls within the rated AC motor drive input
voltage range.
2. Check for possible voltage transients.
3. If DC BUS over-voltage due to regenerative voltage, please increase
the Deceleration Time or add an optional brake resistor.
ovd
Ov at decel
Fault
DC BUS over-voltage during deceleration (230V: DC 450V; 460V: DC
900V)
Corrective Actions:
1. Check if the input voltage falls within the rated AC motor drive input
voltage range.
2. Check for possible voltage transients.
3. If DC BUS over-voltage due to regenerative voltage, please increase
the Deceleration Time or add an optional brake resistor.
ovn
Ov at normal SPD
Fault
DC BUS over-voltage during constant speed (230V: DC 450V; 460V:
DC 900V)
Corrective Actions:
1. Check if the input voltage falls within the rated AC motor drive input
voltage range.
2. Check for possible voltage transients.
3. If DC BUS over-voltage due to regenerative voltage, please increase
the Deceleration Time or add an optional brake resistor.
ovS
Ov at stop
Fault
DC BUS over-voltage at stop
Corrective Actions:
1. Check if the input voltage falls within the rated AC motor drive input
voltage range.
2. Check for possible voltage transients.
LvA
Lv at accel
Fault
DC BUS voltage is less than Pr.06-00 during acceleration.
Corrective Actions:
1. Check if the input voltage is normal
2. Check for possible sudden load
Lvd
Lv at decel
Fault
DC BUS voltage is less than Pr.06-00 during deceleration.
Corrective Actions:
1. Check if the input voltage is normal
2. Check for possible sudden load
