4.2 Function
The safety functions in the DIAS Drive are controlled over two digital inputs.
The following table shows the status that the ENABLE_L and ENABLE_H inputs must
assume to enable normal operation or trigger the safety function.

When the servo
amplifier is supplied
with 24 V, the inputs
are closed after a

• Single channel safe
status only when using
classic I/O technology
• Safe status of the drive

Drive system ready
If the ENABLE_L and ENABLE_H are changed from any status to the "Drive Ready" status,
the servo amplifier is not immediately enabled. In addition, in the software (K-EN = 1) or the
corresponding bit in the "control word" must be set so that the software "enable" can be set
and the drive therefore switched to the operational mode.
