Chapter 9 Setup
9–18
(1) 2-scale 2-motor (2-amplifier) control (System using only main side (CN2 connector side)
feedback)
Setting parameter Master axis Slave axis
SV017/fdir Normally, set the setting value for control. Normally, set the setting value for control.
SV017/vdir2 Set 0. Set 0.
SV025/pen·ent Set AAxx. Set AAxx.
SV028 Normally, set the setting value for control. Normally, set the setting value for control.
(2) 2-scale 2-motor (2-amplifier) control (System also using sub side (CN3 connector side)
feedback)
Setting parameter Master axis Slave axis
SV017/fdir Normally, set the setting value for control. Normally, set the setting value for control.
SV017/vdir2 Set 0. If the master axis and linear motor pole directions are
the same, set to the same setting as SV017/fdir for
the master axis.
If the pole directions are reversed, set the opposite
setting as SV017/fdir for the master axis.
SV025/pen·ent Set AAxx. Set DAxx.
SV028 Normally, set the setting value for control. Normally, set the setting value for control.
(3) 1-scale 2-motor (2-amplifier) control
Setting parameter Master axis Slave axis
SV017/fdir Normally, set the setting value for control. If the master axis and linear motor pole directions are
the same, set to the same setting as SV017/fdir for
the master axis.
If the pole directions are reversed, set the opposite
setting as SV017/fdir for the master axis.
SV017/vdir2 Set 0. Set 0.
SV025/pen·ent Set AAxx. Set AAxx.
SV028 Normally, set the setting value for control. Set the pole shift amount when DC excitation is
carried out with the connected detector.
CAUTION
When carrying out DC excitation with the parallel drive system, if the current
flows to the parallel axis, the machine could break down or the accuracy may
not be satisfied. When carrying out DC excitation with the parallel drive system,
make sure that current does not flow to the parallel axis.
9-3-5 Settings when motor thermal is not connected
POINT
When driving the motor with a system connected to the MDS-B-HR, the servo
driver's protection function will activate if the motor reaches an abnormal
temperature. However, if the wire for the motor's abnormal temperature
monitoring is not connected, the MDS-B-HR will attempt to activate this
protection function. Thus, when driving a motor with a system that does not
have this connection, set the following parameter to ignore the signal from the
MDS-B-HR.
No. Abbrev.
