Analog torque
limit
TLA CN1-27 To use this signal in the speed control mode, set any of parameters
No.PD13 to PD16, PD18 to make external torque limit selection (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 section 3.6.1 (5).)
Resolution:10bit
Analog
input
Analog torque
command
TC 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 section 3.6.3 (1).)
The torque at 8V input can be changed using parameter No.PC13.

VC CN1-2 Apply 0 to 10VDC across VC-LG. Speed set in parameter
No.PC12 is provided at 10V. (Refer to section 3.6.2 (1).)

Used to enter a command pulse train.
In the open collector system (max. input frequency 200kpps)
Forward rotation pulse train across PP-DOCOM
Reverse rotation pulse train across NP-DOCOM
If the command pulse train input is open collector method, it supports
only to the sink (NPN) type interface.
It does not correspond to the source (PNP) type interface.
In the differential receiver system (max. input frequency 1Mpps)
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.
