What to do if the DMG Control Systems low speed is too long?
- K
  Kenneth CampbellAug 20, 2025
  If the low speed phase is taking too long in your DMG Control Systems, especially with a VVVF, it might be due to low engine torque as you approach the floor. To resolve this: 1. Check the 'Low Speed fault time' parameter (section 5.5) and increase it if needed. 2. Examine the elevator speed at low speed (if using VVVF); increase it if necessary. 3. Verify the deceleration distance relative to the indicated plane, especially the magnets or flags FAI/FAS. 4. If an Encoder is used, check the value of the distance R1D/R1S, referring to section 5.9.

  Robert GutierrezAug 22, 2025
  If you are experiencing low tension during movement with your DMG Control Systems, the issue might stem from the motherboard power dropping below 17V. To address this, you should: Check the network, the supply voltage to the transformer primary, the presence of 24V and the consumption of the circuit.
