975
Driver communication
setting error
• Setting the driver communication to servo
amplifier which does not support the
driver communication.
• The driver communication setting is
different in the module and the servo
amplifier.
The communication between servo amplifiers
of target axis is not executed.
(The servo amplifier's LED display remains
"Ab".)
976
Manual pulse
generator/Incremental
synchronous encoder
input type selection
error
The set value of the detailed parameter 2
"Manual pulse generator/Incremental
synchronous encoder input type selection"
is outside the setting range.
The READY signal [X0] is not turned ON.
977
Operation setting for
speed-torque control
mode error
The set value of the detailed parameter 2
"Operation setting for speed-torque control
mode" is outside the setting range.
978
External command
signal selection error
The set value of the detailed parameter 2
"External command signal selection" is
outside the setting range.
979
Synchronous encoder
via servo amplifier
invalid error
• The servo amplifier axis set as
synchronous encoder via servo amplifier
is not supported with scale measurement
mode.
• In system construction, the unset up
servo amplifier axis is set as the
synchronous encoder via servo amplifier.
• In system construction, the axis set to
"Invalid" at the external synchronization
encoder input is set as the synchronous
encoder via servo amplifier.
• The servo amplifier axis set as
synchronous encoder via servo amplifier
is connected to the linear scale.
980 OPR
method
error
The set value of the OPR basic parameter
"OPR method" is outside the setting range.
981 OPR direction error
The set value of the OPR basic parameter
"OPR direction" is outside the setting
range.
982
OP address setting
error
The set value of the OPR basic parameter
"OP address" is outside the setting range.
983 OPR speed error
• The set value of the OPR basic
parameter "OPR speed" is outside the
setting range.
• The set value of the OPR basic
parameter "OPR speed" is smaller than
the bias speed at start.
