Serial communication conguration
Setting9802,togetherwithmountingaparticularFBA
module, automatically sets the appropriate default values in
parametersthatdenethecommunicationprocess.These
parametersanddescriptionsaredenedintheuser’smanual
supplied with the FBA module.
NOTE: This is not required with MicroTech III controls.
• Parameter5101isautomaticallycongured.
• Parameters 5102…5126 are protocol-dependent and
dene,forexample,theproleused,andadditional
I/O words. These parameters are referred to as the
eldbuscongurationparameters.Seetheuser’smanual
providedwiththeFBAmodulefordetailsontheeldbus
congurationparameters.
• Parameter 5127 forces the validation of changes to
parameters 5102…5126. If parameter 5127 is not used,
changes to parameters 5102…5126 take affect only after
the drive power is cycled.
• Parameters 5128…5133 provide data about the FBA
module currently installed (e.g. component versions and
status).
The Parameters section lists the group 51 parameters.
Activate Drive Control Functions – FBA
Fieldbus control of various drive functions requires
congurationto:
• Tellthedrivetoaccepteldbuscontrolofthefunction.
• Deneasaeldbusinput,anydrivedatarequiredfor
control.
• Deneasaeldbusoutput,anycontroldatarequiredby
the drive.
The following sections describe, at a general level, the
congurationrequiredforeachcontrolfunction.Thelast
column in each table below is deliberately blank. See
the user’s manual supplied with the FBA module for the
appropriate entry.
Start/Stop Direction Control
Usingtheeldbusforstart/stop/directioncontrolofthedrive
requires:
• Driveparametervaluessetasdenedbelow.
• Fieldbus controller supplied command(s) in the
appropriatelocation.(Thelocationisdenedbythe
Protocol Reference, which is protocol dependent.)
Table 43: Start/Stop/Direction Control
Drive Parameter Value Description Protocol Reference
1001 EXT1 COMMANDS 10 (COMM) Start/Stop controlled by eldbus with Ext1 selected.
1002 EXT2 COMMANDS 10 (COMM) Start/Stop by controlled eldbus with Ext2 selected.
1003 DIRECTION 3 (REQUEST) Direction controlled by eldbus.
Input Reference Select
Usingtheeldbustoprovideinputreferencetothedrive
requires:
• Driveparametervaluesetasdenedbelow.
• Fieldbus controller supplied reference word(s) in the
appropriatelocation.(Thelocationisdenedbythe
Protocol Reference, which is protocol dependent.)
NOTE: Multiple references are supported only when using
the Daikin Drives profile.
Scaling
Where required, REFERENCES can be scaled. See the
