A larger parameter value would soothe the speed command more obviously. However, the response would slow down as
well. If it is set as zero, this function is disabled.
6.3.4 Torque limit of speed control mode
When this mode is applied, there are two major parameters: PA05 and PC25 which are related to the torque limit
function. They are explained in the following table.
Name Abbr. Sign Setting range Unit Initial value Control mode
Inner torque limit 1 TL1 PA 05 0~100 % 100 Pt、Pr、S、T
Inner torque limit 2 TL2 PC 25 0~100 % 100 Pt、Pr、S、T
Here are 3 pin functions of CN1: 1 analog voltage input and 2 DI inputs which are described below:
Pin/Signal name Abbr. Description Control mode
Torque analog limit TLA
This signal is valid by the setting of PD02~PD09 or PD21~PD24 to make
TL enable. As TLA is valid, the torque output would be limited. When
TLA is connected o the positive polarity of the power source, a maximum
torque will be generated at +10V.
Pt、Pr、S
Torque limit option TL
Set th e PD02~PD09 or PD21~PD24 parameter to enable this signal. As
TL-SG is open circuit, the inner torque limit 1(PA05) is valid. In case of
short circuit, the torque analog limitation (TLA) effective.
Pt、Pr、S
Inner torque limit option TL1 Set the PD02~PD09 or PD21~PD24 parameter to enable this signal. As
TL1-SG is short circuit, the Inner torque limit 2(PC25) effective.
Pt、Pr、S、T
Use the internal torque limit selection (TL1) to set parameter PD02 ~ PD09, than the internal torque limit 2 (PC 25)
can be selected. There are 4 combinations which are decided by the signal state of TL and TL1.The torque limit value (TL),
internal torque limit selection (TL1) and torque limit analog (TLA) restrictions in the following table for selection:
(Note) DI signal status
The valid value of torque limit
TL1 TL
0 0 The setting value of PA05
0 1 If TLA is less than PA05, then TLA is valid. If TLA is greater than PA05 then PA05 is valid.
1 0 If PC25 is less than PA05, then PC25 is valid. If PC25 is greater than PA05, then PA05 is valid.
1 1 If PC25 is less than TLA, then PC25 is valid. If PC25 is greater than TLA, then TLA is valid.
Note 0: OFF(TL1-SG or TL-SG is open-circuit) ,1:ON (TL1-SG or TL-SG is short-circuit)
If the generated torque suits the value of PA05 or PC25 or torque analog limit, the TLC of DO signal becomes conductive
with SG.
Pin/Signal name Abbr. Description Control mode
Torque limiting control TLC
TLC-SG is conductive as the generated torque reaches the inner
torque limit 1(PA05), or the torque analog limit (TLA).TLC-SG is
isolated when SERVO ON (SON) is off.
