In torque controlling:
x Controls output torque from

x Speed limit can be
controlled with remote

Speed can be controlled in
both CCW and CW
directions via IN−A voltage

x Outside the limit
speed range, the
torque proportional to
the difference with the
limit speed is fed back
negatively to take
back the speed to
within the limit range.
Therefore, the motor

varies according to
the load condition.

F2: NC axis move check
F3: NC data teaching
Press “F1” (NC AXIS JOG CHECK) after pressing
ORG in manual, 1 block mode.
2 Set the digital operator to the desired driver. x Setting the digital
operator changes the
display to “run”.
3 Press MODE/SET key to change the display to Cn−00
and then press DATA key to change to 00−00.

times.
Press UP key three times to display to 00−03 and
then press MODE/SET for 4−digit numerics.
5 Pressing UP key increases the value and Down key
decreases the value. Using UP and DOWN keys, set
the monitor display to r0.00 mm.

Press “SEMI” − “1BLOCK” − “RESET” and “START”
and move the X/Y/Z axis. Then press “MANU” −
“1BLOCK” − “ORG.” and “F1” (NC AXIS JOG CHECK)
to make sure each axes indicates r0.00 mm.
xThe values other than
r0.00 mm, shall be
adjusted to r0.00 mm
using UP and DOWN
keys.
