Syncronising Controller MCO 350 Operating
Instructions
19-20 Control source synchronising (Contr. synchron)
Option:
[0]
[1]
19-21 Brake on delay (Brake on delay)
Range:
19-22 Brake off delay (Brake off delay)
Range:
19-23 Marker monitor
Option:
[0]
[1]
Function:
This parameter is used to select the control source in synchro-
nising mode (par. 33-80 = "2"). There can only be one control
source at a time: Digital inputs or field bus control word. Only
exception is input 27 which is always stop also with field-bus
control.
When digital control is selected status signals are updated on
the digital outputs, when field bus control is selected status sig-
nals are updated on digital outputs as well as field bus.
Digital Inputs means that all control commands are activated via the digital
inputs according to the description of the terminals.
Fieldbus means that all control commands are activated via the field bus
control word according to the description of field bus control.
Function:
This parameter is used to specify the delay time between closing
the mechanical brake (output 4) and disabling motor control
(motor coast). This is necessary to avoid loosing the load be-
cause of the reaction time of the mechanical brake.
[0...5000 msec.] The value must be set according to the reaction time of the me-
chanical brake.
Function:
This parameter is used to specify the delay time between acti-
vating motor control and opening the mechanical brake (output
4). This is necessary to avoid loosing the load because of the
reaction time of the mechanical brake.
[0...5000 msec.] The value must be set according to the reaction time of the me-
chanical brake.
Function:
This parameter specifies the behaviour when markers are miss-
ing in Marker synchronising mode (par. 1901 = 2 or 5)
Output 2 Fault is set when "not accuracy" for x number of markers (x =
par. 33-24).
Output 2 Fault is set when "not accuracy" for x number of markers (x =
par. 33-24) OR when x number of markers are missing.
