The following table shows only those settings related to the torque limit function.
Setting
10 Forward Torque Limit
11 Reverse Torque Limit
12 Regenerative Torque Limit
13 Torque reference
(The input limits torque in both the forward and reverse directions during speed control.)
15 Speed Limit (Limits torque in both the forward and reverse directions.)
Set the analog input terminal's signal level, gain, and bias to match the actual input signal. The factory
default settings for the input terminal's signal level are as follows:
Terminal 16: 0 to +10 V (A 10-V input limits the torque to 100% of the motor's rated torque.)
Terminal 14: 4 to 20 mA (A 20-mA input limits the torque to 100% of the motor's rated torque.)
The following diagram shows the relationship between the output torque and each torque limit.

Note 1. When the forward torque limit has been set, the analog input signal acts as the limit value for
torque generated in the forward direction. The torque limit input is effective when torque is
generated in the forward direction even if the motor is operating in reverse (regenerative
torque).
Note 2. The torque limit is 100% of the motor's rated torque when the analog input is at its maximum
value (10 V or 20 mA). To increase the torque limit above 100%, set the input terminal's gain
above 100%. For example, a gain of 150.0% would result in a torque limit of 150% of the mo-
tor's rated torque with a 10-V or 20-mA analog input.
