Manual F5021B - Triggering of frequency inverter
13.Triggering of frequency inverter
SmartCom have 2 kinds of triggering a frequency inverter available:
1. Analog: The converter is triggered via the analog output. The travel curve at this will be created by the
controller, whereby direct drive-in makes possible with every converter with analog input.
2. Multistep binary: The converter provides dependent of 3 binary signals, up to 6 steps of driving. The
travel cycle mostly defined by the converter.Direct drive-in is not possible. Through ideal choice of speed,
it is however possible to reach minimal creep ways. Binary triggering is for most of the industry converters
possible.
Generally
Before start of a journey for all controllers the erroroutput and the ready message of the converter have to
be inactive, also all security contactors (K1, K2, K8) have to be depressed. First of all, after a driving
command the main contactors K1 and K2 will be activated. Via the feedback (contactor monitoring)
SmartCom is checking the activation. If this is effective, the conrol of the converter will be activated. Now
a RUN-signal is happen from the converter to the control. After that the break is opening. The triggering of
the contactore always have to be happen from the controller, as otherwise the timing of the contactor
monitoring would not work.
If you buy the controller completly with converter or provide the converter, it will be pre-programmed and
adjusted with intelligent values at our testbed. Than the normal case you just need to do at face adapting
the motor datas and maybe have to do a auto-tuning.
Triggering Multistep binary
At nearly all industrie-converters it is possible to choose more speeds binary, means e.g. with 3 control
cables it is possible to choose 8 speed variants.
Smartcom is using 3 cables for choosing 6 speeds. Based on this the travel characteristics could be better
optimazed. V1 to V3 intended as follows:
V1: Journey from floor to floor
V2: Journey with a floor in between
V3: Journey with more than one floor in between
In the normal case V1 is enough, but for fast lifts
(V>1,6m/s) or for short stops V1 is needed for Journey
from floor to floor, V2 for long-distance journey. For lifts
faster than that (>3m/s) V3 come into the play.
The proper breaking distances are setted at the encoder
with the speeds, high- respectively lowruntimes and
roundings (S-curve). Which speed is choosen by the
controller depends on the respective prameters in the
controller (F6-F11).
