Data type Meaning
BOOL STO switch-off path A
(all four switch-off paths and STO Active must be set to logic 1 in
order to enable the axis and to logic 0 for the STO function)
BOOL STO switch-off path B
(all four switch-off paths and STO Active must be set to logic 1 in
order to enable the axis and to logic 0 for the STO function)
BOOL STO switch-off path C
(all four switch-off paths and STO Active must be set to logic 1 in
order to enable the axis and to logic 0 for the STO function)
BOOL STO switch-off path D
(all four switch-off paths and STO Active must be set to logic 1 in
order to enable the axis and to logic 0 for the STO function)
BOOL Acknowledgment of a module fault in the STO module
(In the default project this signal is linked with the FSDRIVE
ErrAck input)
BOOL Information sent to the AX8000 about the state of the STO
function. Must be set to logic 1 so that the AX8000 will enable the
axis.
PWM signal for controlling the brake
Enable signal for the brake control
BOOL Acknowledgment of a module fault in the BRAKE module
(In the default project this signal is linked with the FSDRIVE
ErrAck input)
BOOL Acknowledgment of a module fault in the FSIN module
(In the default project this signal is linked with the FSDRIVE
ErrAck input)
BOOL Acknowledgment of a module fault in the FSDRIVE module
(In the default project this signal is linked with the FSDRIVE
ErrAck input)
BOOL Status information about a group error for the AX8000
BOOL Status information about an STO error for the AX8000
BOOL Status information about an input error for the AX8000
BOOL Status information about a brake error for the AX8000
BOOL Status information about an undervoltage error for the AX8000
BOOL Status information about an overvoltage error for the AX8000
BOOL Status information sent to the AX8000 about whether the encoder
is active. (not used so far)
BOOL not used
BOOL used internally to test input 1 on X15 or X25 respectively. Cannot
be used by the user.
BOOL used internally to test input 2 on X15 or X25 respectively. Cannot
be used by the user.
