System manual CECX / Analog input module CECX-A-4E-V
CECX-II 19-8
!
WARNING!
Unintentional switching on of a drive possible!
• If the power supply for the modules is not switched on, but a voltage is
applied to the analog inputs (e.g. by the external supply of an encoder),
there may still be a voltage on the analog outputs.
This enables drives to be switched on even though they have not re-
ceived an ON-command.
Remedy: The drives must only switch after the activation of an enable
output. This must only be switched on after the system startup has
been completed (e.g. via the output of a digital output module)
