Safety notes for electrical drives and controllers
Positioning module IMD20, IMD40
Be careful during the assembly. During the assembly and also later during operation of
the drive, make sure to prevent drill chips, metal dust or assembly parts (screws, nuts,
cable sections) from falling into the device.
Also make sure that the external power supply of the controller (24V) is switched off.
The DC bus circuit or the mains supply must always be switched off prior to switching off
the 24V controller supply.
Carry out work in the machine area only, if AC and/or DC supplies are switched off.

Initial operation must be carried out with idle motors, to prevent mechanical damages
Electronic devices are never fail-safe. It is the user’s responsibility, in the case an
electrical device fails, to make sure the system is transferred into a secure state.
The servo drive controller and in particular the brake resistor, externally or internally, can
assume high temperatures, which may cause serious burns.
