3.1 Controlling of ZETADYN 1DV
Figure 3.1 shows control of a simple travel between two stops, referred to as NORMAL TRAVEL . Please
observe that the wiring plan shown in appendix A8 is met by the control.
Figure 3.1 Normal travel
(1) The higher control sets the direction of
motion for the inputs "RV1/RV2" and
triggers the inputs for the running speed (in
this case "V1" and "V3"). The "controller
release -RF" can already be fed. It is also
possible to connect it only when the
direction and the speed are fed.
By means of the output "Controller active -
RB" the control device indicates that the
input signals have been accepted and that
it is ready for a new run. When switching
"RB" the main contactor K0 has to be
closed.
When switching the output "Mechanical
brake -MB" the control of the brake has to
open immediately and without delay.
(2) The drive accelerates until the preset speed
is reached.
(3) A travel at a constant speed follows, until
the activation of the travel speed ("V3") is
cancelled.
(4) The drive decelerates to the positioning
speed "V_1".
(5) After a short distance covered, the
positioning speed is switched off.
(6) The drive continues to decelerate.
(7) The control device disconnects the output
"MB". The control is to close the brake
without delay.
(8) The main contactor "K0" has to be switched
on until the contactor "RB" is switched off.
The
spring-loaded safety brake
is to be switched on and off by means of the
relay "MB"
.
This is the only guarantee that the control device is able to control start-up and stopping
without jerk.
The
main contactor "K0"
is to be switched on and off by means of the
relay "RB".
This is the
only guarantee that the main contactor is switched in the currentless state and enables start-
up and stopping without jerk.
In case of
trouble
, i.e. when the
relay "ST"
is released, the control has to make sure that the
mechanical brake and the main contactor are immediately switched off.
