5.2.2.3 Signal procedures
5.2.2.3.1 Signal procedure at normal operation (example: up-travel at V4)
Explanations on start-up: The time at which the travel commands are received does not play any
role . As soon as the VVVF controller receives the controller enable ( GS ), direction signal ( RO or RU )
and a speed command ( V4 ), the relay ZS (main contactors) and after the time
ZB auf
the relay ZB
(brake) are activated and initiate the start-up operation.
Explanations on stop procedure:
As soon as the V4 command is withdrawn, the deceleration
operation is initiated, as soon as the V0 command is withdrawn, the unit is decelerated to speed 0.
After the unit has stopped, the relays ZS and ZB are switched off, the delay times can be
parameterised.
