Analog torque
limit TLA To use this signal in the speed control mode, set any of
parameters No. 43 to 48 to make TL available.
When the analog torque limit (TLA) is valid, torque is limited in
the full servo motor output torque range. Apply 0 to 10VDC
across TLA-LG. Connect the positive terminal of the power supply
to TLA. Maximum torque is generated at 10V. (Refer to (5) in
Section 3.4.1.) Resolution:10bit Analog
input
Analog torque
command TC
CN1B
12
Used to control torque in the full servo motor output torque
range.
Apply 0 to 8VDC across TC-LG. Maximum torque is generated
at 8V. (Refer to (1) in Section 3.4.3.)
The torque at 8V input can be changed using parameter No. 26. Analog

Analog speed
command VC Apply 0 to 10VDC across VC-LG. Speed set in parameter No. 25
is provided at 10V. (Refer to (1) in Section 3.4.2.)

Used to enter a command pulse train.
In the open collector system (max. input frequency 200kpps):
Forward rotation pulse train across PP-SG
Reverse rotation pulse train across NP-SG
In the differential receiver system (max. input frequency
500kpps):
Forward rotation pulse train across PG-PP
Reverse rotation pulse train across NG-NP
The command pulse train form can be changed using
parameter No. 21.
