To use this signal in the speed control
NOTICE 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 +10
VDC across TLA-LG. Connect the positive terminal of the
power supply to TLA. Maximum torque is generated at +10
V. (Refer to 1), (1) in Section 3-1-3.))
Resolution: 10 bit
Used to control torque in the full servo motor output torque
CN1B
range.

Apply -8 to +8VDC across TC-LG. Maximum torque is
generated at +8V.
(Refer to 1), (1) in Section 3-1-3.) Resolution: 10 bit
CN1B Apply -10 to +10VDC across VC-LG. Speed set in
2 parameter No. 25 is provided at +10V. (Refer to 1), (2) in
Section 3-1-3.)
Resolution: 12 bit or equivalent
CN1B Apply -10 to +10VDC across VLA-LG. Speed set in
2 parameter No. 25 is provided at +10V. (Refer to 1), (3) in
Section 3-1-3.)
Resolution: 12 bit or equivalent
CN1A Used to enter a command pulse train.
3 • In the open collector system (max. input frequency
CN1A 200kpps):
2 Forward rotation pulse train across PP-SG
CN1A Reverse rotation pulse train across NP-SG
13 • In the differential receiver system (max. input frequency
CN1A 400kpps):
12 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.
