. The set analog input terminal (AI2) signal level (04-00), gain (04-07) and bias (04-08)
meet the actual input signal. The default setting of the analog input terminal signal
level is shown as the following:
AI2 = 0 to10V (10V input torque limit to 100％ of the motor rated torque)
.The figure 4.3.128 below is the relationship of the output torque and the torque limit

─When the forward torque limit has been set (set value = 11), the analog input
signal is the forward torque limit value. When the torque is based on the rated
forward direction, the forward torque limit input is valid even if the motor is
operating in the reversal direction, (namely the regenerating torque is in the
second quadrant).
─When the reversal torque limit has been set (set value = 12), the analog input
signal is the reversal torque limit value. When the torque is based on the rated
reversal direction, the reversal torque limit input is valid even if the motor is
operating in the forward direction, (namely the regenerating torque is in the fourth
quadrant).
─When the regenerating torque limit has been set (set value = 13), the analog input
signal is forward (the fourth quadrant) or reversal (the second quadrant)
regenerating area.
─When the forward / reversal torque limit has been set (set value = 14), the analog
input signal is forward or reversal limit value.
─When the analog input is the maximum (10V or 20mA), the torque limit is 100% of
the motor rated torque. In order to increase the torque limit above 100%, set the
input terminal gain (04-07) above 100%. For example: 200.0% of the gain will
