Torque Limits Using an Analog Input
Topic Description

The GA800, GA500, HV600, A1000, U1000, and V1000 drives have the capability of using an analog input to set a general torque limit.

Note: A torque limit is only available in OLV, CLV, AOLV, AOL/PM, CLV/PM, and EZOLV control modes.


Resolution

To set a general torque limit with an analog input, assign an analog input (A1, A2, or A3) and set H3-0x = 15 (general torque limit).

  • The torque limit is based on the Gain setting of the analog input.
    • Example: If using terminal A1 (H3-02 = 15) and H3-03 = 100% (Terminal A1 Gain), the drive will be limited to 100% torque.
  • Parameters L7-01 (Forward Torque Limit), L7-02 (Reverse Torque Limit), L7-03 (Forward Regenerative Torque Limit), and L7-04 (Reverse Regenerative Torque Limit) also define the torque limit.
    • The drive will use the lower of the two values (either analog input or L7-01 to L7-04) as the torque limit, depending on the quadrant (see picture below).
