Chapter 14 Common Functions
(f) If all axes set to driver communication are not detected at the start of
communication with the servo amplifier, all axes including independent
axes cannot be operated. (The servo amplifier's LED display remains
"Ab".) Check the operation enabled status with "
Md.52
Communication
between amplifiers axes searching flag
". When all independent axes and
axes set to driver communication are connected, "0: Search end" is
set in "
Md.52
Communication between amplifiers axes searching flag
".

(2) OPR control, positioning control, manual control, expansion control, and
synchronous control
(a) Do not start the slave axis. The command to servo amplifier is invalid
even if the slave axis is started.
(b) The OPR request flag (
Md.31
Status: b3
) of slave axis is always ON.
There is no influence for control of slave axis.
(c) There are some restrictions for data used as the positioning control of
slave axis. The external input signals such as FLS or RLS, and the
parameters such as software stroke limit are invalid.
Refer to this section (4) or (5) for details.
(d) For setting the slave axis as a servo input axis, set "2: Real current
value" or "4: Feedback value" in "
Pr.300
Servo input axis type
". Otherwise,
the slave axis does not operate as an input axis.
(e) At the driver communication operation, only the switching to positioning
control mode, speed control mode, and torque control mode are
possible. When the mode is switched to continuous operation to torque
control mode for the master axis, the warning "Control mode switching
not possible" (warning code: 125) will occur, and the control mode is not
switched.
(3) Absolute position system
Set "0: Disabled (incremental system)" in "Absolute position detection
system (PA03)" of servo parameter for slave axis. If "1: Enabled (absolute
position detection system)" is set, the error "OPR data incorrect" (error code:
1201) will occur and the OPR of slave axis cannot be executed.
