Comparison of the control modes "Terminals 0/2/11/16"
The following table shows which functions of the preset application "actuating drive speed" have
been preconfigured in the prevailing control mode for a control via terminals (Lenze setting printed
in bold):

Overriding fixed setpoints Alternatively to the speed selection via the analog
input, "fixed setpoints" (JOG values" can also be
activated via the digital terminals.

LOW LOW Via analog input 1
(Terminal A1U)
HIGH LOW Fixed setpoint 1
(C00039/1: 40 %)
LOW HIGH Fixed setpoint 2
(C00039/2: 60 %)

(C00039/3: 80 %)
DI3 - DI2 - Manual
DC-injection braking
Manual DC-injection braking allows the drive to be
quickly braked to a standstill without the need to use
an external brake resistor.
- DI3 - - Quick stop The quick stop function decouples the motor control
from the setpoint selection. The motor is braked to
standstill with the adjustable ramp time (n
act
= 0).

an alternative setpoint source which is controlled via
two inputs.  Motor potentiometer ( 65)
