[C0490] Feedback pos 0 Feedback system for the speed con-

troller

• C0490 = 0, 1, 2 can be mixed

with

C0495 = 0, 1, 2.

• C0490 = 3, 4 sets C0495 to the

same value.

[C0495] Feedback n Feedback system for the speed con-

troller

• C0495 = 0, 1, 2 can be mixed

with

C0490 = 0, 1, 2.

• C0495 = 3, 4 sets C0490 to the

2.12.15 Touch probe (TP)

Process: The current angle value (digital frequency input value) is stored by a quick interrupt in the

operating system when a signal change occurs at the TP activating input (e.g. X5/E4).

Why does Lenze DC Drives motor rotate at Imax and 50 % slip frequency?
- D
  Derek HamptonJul 30, 2025
  The Lenze DC Drives motor might be rotating at Imax and 50% slip frequency because the motor is not connected in-phase. To resolve this, connect the motor in-phase at the terminals U, V, W.
