Delta LiT fault code meaning

Series: C2000 Plus, CH2000, MH300

Limit error encountered

AC motor drive

Meaning: In control modes other than IMFOCPG / PMFOCPG, this fault code occurs when the AC motor drive operates in speed mode and the reverse operation inhibit limit or forward operation inhibit limit at terminal MI is activated.

Possible causes

• Check whether the sensor is normal.
• Check whether terminal MI is activated incorrectly.
• Check whether the deceleration time is too long.

Series: DPD-K

Limit error encountered

AC motor drive

Meaning: During operation, a limit error occurs when MIx = 45 (forward limit) or MIx = 44 (reverse limit) is activated. (This fault code is not available on DPD-K.)

Possible causes

• Incorrect limit switch position
• The deceleration time is too long, preventing the motor from stopping within the specified
• Stop within position
• Activation of the overvoltage stall prevention function causes the motor
• Cannot stop
• Malfunction due to interference
