Digital Inputs DIGITAL-IN 1...2 (X3A/2,3):
These inputs are particularly fast and are therefore suitable for latch functions or for
high-speed feedback signals, for example.

—
—
Digital Inputs DIGITAL-IN 3...4 (X3A/4,5):
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).
—
—
—
Digital Inputs DIGITAL-IN 21...22 (X3A/6,7):
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).
—

Depending on the selected function the inputs are high or low active.

Connector X4
You can thus achieve a restart lock for functional safety by using the STOx-enable inputs
in conjunction with an external safety circuit.
Inputs STO1-ENABLE (X4/7), STO2-Enable (X4/5)

These inputs are not compatible with IEC 61131-2.
These additional digital inputs release the power output stage of the amplifier as long as a
24 V signal is applied to these inputs. If one STOx-Enable input goes open-circuit, then
power will no longer be supplied to the motor, the drive will lose all torque and coast
down to a stop.
NOTICE
Failsafe braking of the drive, if required, must be provided by means of an additional
mechanical brake, since electrical braking by the drive is no longer possible.
You can find further information and connection examples on page 37ff.
