Explanation
Assignment of the digital input according to pin layout
The connected servo amplifier outputs the signal. The product
interprets the signal as an error signal. If an error is present at the
input, the axis is is disconnected from power and abruptly brought
to a standstill without a ramp. An error message is displayed on
the product
Default value: Not connected
Signal is low-active
If the function is active, a "low" signal at the input is interpreted
as an error. Release is given with a "high" signal
Assignment of the digital input for activation of the mechanical
handwheel
If the input is present, no NC movements can be executed with the
axis. If the axis is in closed-loop control and the Input for activat-
ed mechanical handwheel switches, the axis is slowed down in a
controlled manner and taken out of closed-loop control. When the
input is no longer present, the axis can be moved in closed-loop
control again
Default value: Not connected
Signal is low-active
If the function is active, a "low" signal at the input is interpreted
as a mechanical handwheel
Assignment of the digital input for activating access to the central
drive
If a signal is present at this input, the axis gets access to the
central drive
Default value: Not connected
Signal is low-active
If the function is active, access to the central drive is granted
when a "low" signal is present at the input
Assignment of the digital input for enabling the negative traverse
direction of an axis
If a signal is present at this input, the negative traverse direction
of an axis is enabled via the central drive. Otherwise, the positive
traverse direction applies
Default value: Not connected
Signal is low-active
If the function is active, a "low" signal at the input is interpreted
as approval
