V/f setting is not operating as
expected.
Excessive torque compensation.
Drive fails to operate properly due
to noise interference.
Overexcitation gain is set too high.
Run command applied while motor
was coasting.
The wrong motor code has been
entered for PM Open Loop Vector
(Yaskawa motors only).
The motor control method and
motor do not match.
The motor cable is too long

• Check the ratios between the voltage and frequency.
• Set parameter E1-04 through E1-10 appropriately. Set E3-04 through E3-10
when using a second motor.
• Lower the voltage if it is too high relative to the frequency.
• Check the amount of torque compensation.
• Reduce the torque compensation gain (C4-01) until there is no speed loss and
less current.
• Review the possible solutions provided for handling noise interference.
• Review the section on handling noise interference and check the control circuit
lines, main circuit lines and ground wiring.
• Check if fault occurs simultaneously to overexcitation function operation.
• Consider motor flux saturation and reduce the value of n3-13 (Overexcitation
Deceleration Gain).
• Enable Speed Search at start (b3-01 = "1").
• Program the Speed Search command input through one of the multi-function
contact input terminals (H1-oo = "61" or "62").
Enter the correct motor code to E5-01 to indicate that a PM motor is connected.
Check which motor control method the drive is set to (A1-02).
• For IM motors, set A1-02 = "0" or "2".
• For PM motors, set A1-02 = "5".
Use a larger drive.
Option Card Fault (Port A)
The option card is incompatible with the drive.
Option Card Fault (Port A)
Replace the option card.
Option Card Fault (port A)
Option card self-diagnostic error
Option Card Fault (port A)
An error occurred attempting to write to the option card memory.
Option Card Fault (port A)
Communication ID error
Heatsink Overheat
The temperature of the heatsink exceeded the value set to L8-02. Default value
for L8-02 is determined by drive capacity (o2-04).
