Parameter Settings

You can individually set the two overtorque/undertorque detection functions with the drive. Use the information in Table 1 to set the parameters.

Table 1. Overtorque/Undertorque Detection Parameters

Configuration Parameter

Overtorque/Undertorque Detection 1

Overtorque/Undertorque Detection 2

MFDO Function Select

  • Terminal M1-M2

  • Terminal M3-M4

  • Terminal P1-C1

  • Terminal P2-C2

H2-01, H2-02, H2-03, and H2-04 = B

N.O.: Activated when detected

H2-01, H2-02, H2-03, H2-04 = 18

N.O.: Activated when detected

H2-01, H2-02, H2-03, H2-04 = 17

N.C.: Deactivated when detected

H2-01, H2-02, H2-03, H2-04 = 19

N.C.: Deactivated when detected

Note:

The drive sets the Overtorque/Undertorque detection level in these conditions:

  • V/f, CL-V/f, OLV/PM: Current level (drive rated current = 100%)

  • OLV, CLV, AOLV, AOLV/PM, CLV/PM, EZOLV: Motor torque (Motor rated torque = 100%)

  • L6-08 ≠ 0 [Mechanical Fatigue Detect Select ≠ Disabled]: Current level (drive rated output current = 100%)

1

You can also use an analog input terminal to supply the torque detection level. To enable this function, set H3-xx = 7 [MFAI Function Selection = Overtorque/Undertorque DetectLvl]. If you set L6-02 and H3-xx = 7, the analog input is most important and the drive disables L6-02.

You cannot use Overtorque/Undertorque Detection 2 to set the detection level for the analog input terminals.
