Control source test run (Contr. testrun):
753
This parameter is used to select the control source in test run mode (par. 701 = "1").
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 signals are updated on digital outputs as well as field
bus.
Setting range:
0 = Digital inputs
1 = Field bus
"0" means that all control commands are activated via the digital inputs according to the
description of the terminals.
"1" means that all control commands are activated via the field bus control word according
to the description of field bus control.
NOTE: The new control source selected in par. 753 is not active before next power up
(power cycle), remember to save (par. 710 or input 4) the settings before power down.
Control source synchronizing (Contr. synchron):
754
This parameter is used to select the control source in synchronizing mode (par. 701 = "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 signals are updated on digital outputs as well as field
bus.
Setting range:
0 = Digital inputs
1 = Field bus
"0" means that all control commands are activated via the digital inputs according to the
description of the terminals.
"1" means that all control commands are activated via the field bus control word according
to the description of field bus control.
NOTE: The new control source selected in par. 754 is not active before next power up
(power cycle), remember to save (par. 710 or input 4) the settings before power down.
Brake on delay (Brake on delay):
755
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 because of the reaction time of the mechanical brake.
Setting range:
0 ... 5000 msec.
The value must be set according to the reaction time of the mechanical brake.
