To Next PageTo Next PageWhy is my INVT VCP Air Conditioner motor showing overload?
Motor overload in your INVT Air Conditioner can be caused by an inappropriately set motor protection parameter F9-01 or if the load is too large/motor is blocked. Refer to fault code descriptions and solutions in Table 4-1.
What causes accelerated overcurrent in INVT VCP Air Conditioner?
Accelerated overcurrent in your INVT Air Conditioner can be due to several reasons: * A ground or short circuit in the output circuit. * Rapid acceleration conditions with a too-short acceleration time setting. * An inappropriate setting for overrun speed suppression. * Start-up of rotating motors. Refer to fault code descriptions and solutions in Table 4-1.
What causes deceleration overcurrent in INVT VCP Air Conditioner?
Deceleration overcurrent in your INVT Air Conditioner may be caused by: * A ground or short circuit in the output circuit. * The deceleration time setting being too short for acute deceleration. * An inappropriate setting for overrun speed suppression. Refer to fault code descriptions and solutions in Table 4-1.
What causes accelerated overvoltage in INVT Air Conditioner?
Accelerated overvoltage in your INVT Air Conditioner can occur due to: * High input voltage. * External force dragging the motor during acceleration. * Improper overvoltage suppression setting. * Acceleration time being too short. Refer to fault code descriptions and solutions in Table 4-1.
What causes deceleration overvoltage in INVT Air Conditioner?
Deceleration overvoltage in your INVT Air Conditioner may happen because of: * Improper overvoltage suppression setting. * External force dragging the motor during speed reduction. * Deceleration time being too short. Refer to fault code descriptions and solutions in Table 4-1.
What causes constant speed overcurrent in INVT Air Conditioner?
Constant speed overcurrent in your INVT Air Conditioner can be caused by: * A ground or short circuit in the output circuit. * Inappropriate setting for overrun speed suppression. * Inverter selection being too small. Refer to fault code descriptions and solutions in Table 4-1.
What causes motor phase-to-phase short circuit in INVT VCP Air Conditioner?
A motor phase-to-phase short circuit in your INVT Air Conditioner is caused by a two-phase short circuit in output UVW. Refer to fault code descriptions and solutions in Table 4-1.
