Setting A Torque Limit Value In User Constant Cn-13 - YASKAWA SGM series User Manual

APPLICATIONS OF Σ-SERIES PRODUCTS
3.2.9 Using Torque Restriction by Analog Voltage Reference cont.
3
96
To use this function, input a speed reference to the V-REF terminal and a torque limit val-
ue to the T-REF terminal.
This function cannot be used for torque control.
Torque restriction cannot be set separately for forward and reverse rotation. (The same
setting applies to both forward and reverse rotation.)
Setting
Uses the T-REF terminal as a torque reference or torque feed-forward reference
0
input terminal.
1 Uses the T-REF terminal as a torque limit value input terminal.
• This function cannot be used with the torque feed-forward function described in 3.2.8
Using Torque Feed-forward Function.
• For user constants and control modes, refer to Appendix D List of User Constants.

3) Setting a Torque Limit Value in User Constant Cn-13

The factory setting is Cn-13 = 30. If, for example, the torque limit value is 3 V, torque is
restricted to 100% (rated torque). A torque value in excess of 100% is clamped at 100%.
