The drive does not detect mechanical weakening.

1
oL5 @ Speed > L6-09 - Alarm

When the speed (signed) ≥ L6-09 [Mech Fatigue Detect Speed Level], the drive detects mechanical weakening. The drive will detect oL5 [Mechanical Weakening Detection 1] and continue operation.

2
oL5 @ |Speed| > L6-09 - Alarm

When the speed (absolute value) ≥ L6-09, the drive detects mechanical weakening. The drive will detect oL5 and continue operation.

3
oL5 @ Speed > L6-09 - Fault

When the speed (signed) ≥ L6-09, the drive detects mechanical weakening. The drive will detect oL5 and stop operation.

4
oL5 @ |Speed| > L6-09 - Fault

When the speed (absolute value) ≥ L6-09, the drive detects mechanical weakening. The drive will detect oL5 and stop operation.

5
UL5 @ Speed < L6-09 - Alarm

When the speed (signed) ≤ L6-09, the drive detects mechanical weakening. The drive will detect UL5 [Mechanical Weakening Detection 2] and continue operation.

6
UL5 @ |Speed| < L6-09 - Alarm

When the speed (absolute value) ≤ L6-09, the drive detects mechanical weakening. The drive will detect UL5 and continue operation.

7
UL5 @ Speed < L6-09 - Fault

When the speed (signed) ≤ L6-09, the drive detects mechanical weakening. The drive will detect UL5 and stop operation.

8
UL5 @ |Speed| < L6-09 - Fault

When the speed (absolute value) ≤ L6-09, the drive detects mechanical weakening. The drive will detect UL5 and stop operation.

Mech Fatigue Detect Speed Level

Sets the speed level where the drive will operate the mechanical deterioration detection function, as a percentage of the Maximum Output Frequency.

Note:

Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output frequency.

  • A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]

  • A1-02 = 8: E9-02 [Maximum Speed]
