4.3.2 "Safe torque off active" state
This device state becomes active if the controller receives the "Safe torque off" request by the safety
module.
• "Drive is torqueless" (0x00750003) is entered in the logbook.
• If no corresponding request by the safety module is available, a change to the subsequent state
"Device is ready to switch on" is effected.
4.3.3 "Device is ready to switch on" state
This is the device state of the controller directly after the initialisation has been completed and
where no DC-bus voltage is applied yet.
• The bus systems are running and the terminals and encoders are evaluated.
• The monitoring functions are active.
• The controller can be parameterised and device commands can be executed to a limited extent.
• The functions of the user task can be used.
• Precondition: The application has started (status display in C02108 ).
• The basic drive functions cannot be used yet.

The "Safe torque off active" status is also passed through after an error has been
acknowledged (see illustration [4-24] ).

OFF "Device is ready to switch on"

Note!
The "Device is ready to switch on" status is not only activated after mains connection but
also after reset of "Trouble", "Fault", or "Safe torque off active".
• In order to change from the "Device is ready to switch on" to the "Device is switched
on" status when C00142 = "0: inhibited", at least one of the controller inhibit sources
must be active.
• When C00142 = "1: Enabled", the "Device is ready to switch on" status directly
changes to the "Device is switched on" status.
