6.6.4. Torque limit of speed control mode
There are 2 parameters: PA05 and PC25 which are related to the torque limit function.
Here are 3 pin functions of CN1: 1 analog voltage input and 2 DI inputs which are described below:
This signal is valid by the setting of PD02~PD09
to make TL enable. As TLA is valid, the torque
output would be limited. When TLA is connected
to the positive polarity of the power source, a
maximum torque will be generated at +10V.
Set the PD02~PD09 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.
Inner torque limit option
Set the PD02~PD09 parameter to enable this
signal. As TL1-SG is short circuit, the Inner
torque limit 2(PC25) effective.
There are 4 combinations which are decided by the signal state of TL and TL1.
The valid value of torque limit
The setting value of PA05
If TLA is less than PA05, then TLA is valid.
If TLA is greater than PA05 then PA05 is valid.
If PC25 is less than PA05, then PC25 is valid.
If PC25 is greater than PA05, then PA05 is valid.
If PC25 is less than TLA, then PC25 is valid.
If PC25 is greater than TLA, then TLA is valid.
(*) 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.
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.
