Functional Description

The parameter specifies for which safety-related function the InverterEnable input is to be used.

Value	Data type	Meaning
Safe Torque Off / 0	DINT	Safe Torque Off of the axis. The InverterEnable input can be disabled any time. When switching off the InverterEnable, the drive becomes torque-free. No diagnostic message is triggered.
Safe Stop 1 / 1	DINT	Safe stop of the axis. The InverterEnable input can only be deactivated without diagnostic message if the axis is not in closed-loop control. When switching off the InverterEnable, the drive becomes torque-free. If the InverterEnable is switched off while the drive is in closed-loop control (AxisState ≥ 2), then the diagnostic message 8123 Safe Torque Off incorrect is triggered. If the drive is not in closed-loop control (AxisState ≤ 1), then no diagnostic message is triggered. NOTE: This safety-related function can only be achieved with an additional external protective switching device (for example, Preventa XPSAV11113). For further information, see the operating manual of the device.

Value

Data type

Meaning

Safe Torque Off / 0

DINT

Safe Torque Off of the axis.

The InverterEnable input can be disabled any time.

When switching off the InverterEnable, the drive becomes torque-free. No diagnostic message is triggered.

Safe Stop 1 / 1

DINT

Safe stop of the axis.

The InverterEnable input can only be deactivated without diagnostic message if the axis is not in closed-loop control.

When switching off the InverterEnable, the drive becomes torque-free.

If the InverterEnable is switched off while the drive is in closed-loop control (AxisState ≥ 2), then the diagnostic message 8123 Safe Torque Off incorrect is triggered.

If the drive is not in closed-loop control (AxisState ≤ 1), then no diagnostic message is triggered.

NOTE: This safety-related function can only be achieved with an additional external protective switching device (for example, Preventa XPSAV11113). For further information, see the operating manual of the device.

The state of the InverterEnable input is displayed in the parameter InverterEnable.

NOTE: If the InverterEnable is switched off while the drive is in closed-loop control and the motor is moving, then the motor coasts down while the drive becomes torque-free. The behavior of the brake during the coast down is determined by the parameter BrakeMode.
