To use this signal in the speed control
mode, set any of parameters No. 43 to
48 to make TL available.
NOTICE
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.))

Used to control torque in the full servo motor output torque
range.
Apply -8 to +8VDC across TC-LG. Maximum torque is
generated at +8V.

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
400kpps):
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.
