ALSP
ALSP Motor power turn-off method when SPM alarm 24 (serial data transfer
error) is issued.
0 : Turns off the power after the motor is decelerated and stopped.
1 : Turns off the power to the motor immediately (Set to “1”)
Remark
During Spindle Tandem Control is active, it is necessary to turn-off
the motor power (both master and slave) when any alarm occurs to
avoid machine breakage
Be sure to set both ALSP to “1” to turn-off motor power immediately
at SPM alarm 24(serial data transfer error ).

SPDTDM
SPDTDM Function bit of Spindle Tandem Control（CNC software option is
required）
0 : Spindle Tandem Control is unavailable
1 : Spindle Tandem Control is available
Remark
Torque Tandem Control doesn’t work correctly if this bit is “0”. Confirm
CNC software option in case of “0”.

MASTER SLAVE
SLAVE Setting of slave axis of communication between SPMs
0 : non- slave axis of communication between SPMs
1 : slave axis of communication between SPMs
Set to “1” to slave SPM.
MASTER Setting of master axis of communication between SPMs
0 : non- master axis of communication between SPMs
1 : master axis of communication between SPMs
Set to “1” to master SPM.

RVSVC2 VFBAV
VFBAV Setting of velocity feedback at Torque Tandem Control
0 : use only master’s feedback for velocity control
1 : use average value of master’s feedback and slave’s
for velocity control
Mechanical vibration may be reduced by using average value of
master’s feedback and slave’s for velocity control.
