C0412/1.
ƒ The setpoint source for manual operation must be linked with NSET1−N2 under
C0412/2.
ƒ A digital input signal must be linked with the manual/remote changeover
(DCTRL1−H/Re) under C0410/17.
ƒ HIGH active inputs:
– Manual operation active if signal source for DCTRL1−H/Re = HIGH
Activation of "bus operation
ó keypad or PC"
1. Internally invert a digital input (X3/E5 or X3/E6) not used in the Lenze setting under
C0411.
2. Assign this input C0410/17 (DCTRL1−H/Re) to activate manual operation.
3. If the inversion of the digital input reset (C0411 = 0), remote operation will be active
again.
