Figure 154:
Ramps View
Travel Limit Decel – The deceleration ramp is used if either a Software or Hardware Travel Limit is encountered. The
deceleration units of the ramp are defined in the User Units view under the Acceleration group.
Torque View
If the application calls for specific torque levels and limits, use the parameters on this view.
Tuning View
Control Techniques' Drives are designed to handle a 10:1 inertia mismatch without a tuning requirement. If you have
calculated and know the inertia mismatch, the value can be entered on the Tuning view for ideal drive response and velocity
regulation.
Figure 155:
Tuning View
Inertia Ratio - This parameter is the ratio between the reflected inertia of the load and the inertia of the motor rotor. For
assistance in calculating the Inertia ratio, see the Determining Tuning Parameter Values section of this manual.
PLS View
Use this view to setup Programmable Limit Switches (PLS), if the application requires them. They are assigned in the same
way as the Assignments views in Step 3 below.
