7.15.2.2 Connector X3A, X3B
Input ENABLE
— PLC compatible (IEC 61131-2 type 1), floating, reference ground is DGND
— High: 15...30 V / 2...15 mA , Low: -3...5 V / <1mA
— Update rate: Software 250 µs
The output stage of the servo amplifier is enabled by applying the ENABLE signal (Termi-
nal X3A/1, active high). Enable is possible only if inputs STOx-Enable have a 24 V signal
(see page 41ff). In the disabled state (low signal) the connected motor has no torque.
A software enable by means of the setup software is also required (AND link), although
this can also be permanently enabled (“Basic Setup” screen page of the DRIVEGUI.EXE
setup software).
Programmable digital inputs
(X3):
You can use the digital inputs X3A/2 to X3A/7 to initiate pre-programmed functions that
are stored in the servo amplifier. A list of these pre-programmed functions can be found
on the “Digital I/O” screen page of our setup software.
If an input was freshly assigned to a pre-programmed function, then the data set must be
saved in the EEPROM of the servo amplifier and a reset has to be carried out (with the
amplifier setup software for example).
Digital Inputs DIGITAL-IN 1 and DIGITAL-IN 2 (X3A/2,X3A/3):
These inputs are particularly fast and are therefore suitable for latch functions or for
high-speed feedback signals, for example.
— PLC compatible (IEC 61131-2 type 1), floating, reference ground is DGND
— High: 15...30 V / 2...15 mA , Low: -3...5 V / <1mA
— Update rate: Hardware 2µs
Digital Inputs DIGITAL-IN 3 and DIGITAL-IN 4 (X3A/4,X3A/5):
The PSTOP and NSTOP limit switch evaluation functions, for instance, can be assigned
to these inputs. Choose the function you require in the setup software (“Digital I/O”
screen page).
— PLC compatible (IEC 61131-2 type 1), floating, reference ground is DGND
— High: 15...30 V / 2...15 mA, Low: -3...5 V / <1mA
— Update rate: Software 250 µs
Digital Inputs DIGITAL-IN 21 and DIGITAL-IN 22 (X3A/6,X3A/7):
Pins 6 and 7 on X3A can be used as either inputs or outputs. Choose the function you
require in the setup software (“Digital I/O” screen page).
— PLC compatible (IEC 61131-2 type 1), floating, reference ground is DGND
— High: 15...30 V / 2...15 mA, Low: -3...5 V / <1mA
— Update rate: Software 250 µs
Depending on the selected function the inputs are high or low active.
