MCS- 46/92
Digital Brushless AC servo drive system - Ref.0707
Initialization and adjustment
After starting the motor-drive system, the way the parameters, variables and commands
will be displayed and edited will be determined by the access level: Fagor level, user level
or basic level restricting, depending on the level, the access to some or all of them.
This access level is determined by entering its corresponding code in the GV7 variable.
This way, with no access level, the following variables may be displayed in this order:
SV1: VelocityCommand.
SV2: VelocityFeedback
CV3: CurrentFeedback
To access the rest, access GV7 and browse through as shown below:
If the code is correct, all the parameters, variables and commands permitted by that level
may be accessed by turning the rotary decoder. If it is not correct, it will display 4 horizontal
lines and the GV7 again allowing to write the level code again.
If the system consist of an MCS drive with a motor having an
encoder with an
incremental
I0
, the drive must be told which type motor it must govern by means of
parameter
MP1
. When connecting a motor that uses a
SINCOS™ or SINCODER™
encoder, this is not necessary because the encoder will "tell" the drive which type of motor
it is mounted on.
Although it is less frequent, in the case of the sincoder, it is also possible that the sincoder
does not inform the drive about the type of motor it is installed in; thus the MP1 parameter
must be edited like encoder I0. To operate in this mode, the automatic initialization of
the encoder must be disabled by setting parameter GP15 = 0.
Once the MP1 has been found by turning the decoder until it appears on the display, follow
the sequences indicated in the section “parameters, variables and commands” in this
manual.
Once the motor has been defined, it must be initialized with the GC10 variable in order
to set the initial values for the drive that matches the selected motor. Once the GC10
has been found by turning the decoder until appears on the display. The sequence to
follow is shown below:
CV3
CurrentFeedback
SV2
VelocityFeedback
SV1
VelocityCommand
It is displayed only when the code stored in
the GV7 variable in that instant (to define the
access level) is wrong.
