1.11 Switch-on/-off behaviour
The diagram below illustrates the correct functional sequence for switching the servo amplifier on
and off.
1.11.1 Stop function as per EN 60204 (VDE 0113)
If a fault occurs (� p.60), the output stage of the servo amplifier is switched off and the BTB/RTO
contact is opened. In addition, a global error signal can be given out at one of the digital outputs
(terminals X3/8 and X3/9) (see the Online help in the setup software, or the manual for the setup
software). These signals can be used by the higher-level control to terminate the current PLC cycle
or to shut down the drive (through an additional brake or similar means).
Instruments with a selected Brake function use a special sequence for switching off the output stage
(� p.19).
The Stop functions are defined in EN 60204 (VDE 0113), Paras. 9.2.2 and 9.2.5.3.
There are three categories of Stop functions:
Category 0: Shut down by immediate switch-off of the supply of energy to the
drive machinery (i.e. an uncontrolled shut-down)
Category 1: A controlled shut-down, during which the supply of energy to the
drive machinery is maintained to perform the shut-down, and where
the supply is only interrupted when standstill has been reached
Category 2: A controlled shut-down, where the supply of energy to the drive
machinery is maintained
Every machine must be equipped with a Stop function to Category 0.
Categories 1 and/or 2 must be provided if the safety or functional requirements of the machine
make this necessary.
