Operation Manual of INVT CHS100 AC Servo Drive 6 Detailed parameter description
68
It is used to select the input manner of the torque command in the torque mode:
0: Internal torque command. At this time we can set the desired torque by setting the
internal torque command parameter (PA.11).
1: External analog torque command. At this time we can control the output torque by
applying a voltage between -10V and 10V on the analog torque input terminals (TA). By
factory default, the positive value means forward and negative value means reverse.
But it can be changed by setting parameters Pc.32 – Pc. 35.
In the speed mode or position mode, it is used to select the input manner of the torque
limit:
0: internal torque limit. At this time we can limit the magnitude of the output torque by
setting the internal torque limit parameter (PA.12). The direction of the torque limit is
the same as that of the speed command.
1: External analog torque limit. At this time we can limit the output torque by applying a
voltage between -10V and 10V on the analog torque limit terminals (TA). The
magnitude of the torque limit is the absolute value of the analog input, the direction of it
is the same as that of the torque command.
Please note that in the torque mode, do not allow the motor to run under the condition
of negative load.

The servo drive provides 4 steps of internal speed command/internal speed limit:
parameters PA.09, PA.10, Pc.10, Pc.11.
In the speed mode, this group of parameters is used to set the value of internal speed
setting. We can select which parameter gives out the internal speed command through
the speed selection terminal (SC1 and SC2). The corresponding relationships are
listed in the table below:
