OUTPUT
ERROR CAUSES ACTION TO BE TAKEN
Non Operation • Input voltage drop Check the main circuit DC voltage in Un-xx. If the
voltage is low, adjust the input voltage.
Non Operation • Input voltage rise Check the main circuit DC voltage in Un-xx. If the
voltage is high, adjust the input voltage.
Non Operation • Overload Replace the cooling fan and clean the filter.
• Cooling fan fault Ambient temperature:
• Ambient temperature rise 104 of (40 °C) or less for enclosed type
• Clogged filter 122 of (45 °C) or less for open chassis
Non Operation • Motor current exceeded the set value because of Check the driven machine and correct the cause of the
machine fault or overload. fault or set to a higher value.
• Insufficient power for accel/decel • Set proper accel/decel time for smooth operation.
Non Operation • Overload • For stall prevention during normal operation lighten
• Phase loss the load or increase AC Drive capacity.
Non Operation Operation sequence error • Recheck the control sequence.
• 3-wire/2-wire selection error • Recheck system constant (Sn-15 to -18)
Non Operation • External fault conditions set-up • Take appropriate measures for the cause of
external fault input.
• Transmission between the AC Drive and digital
