Step 2. Enter the desired speed response and overshoot damping values.
Step 3. Click Calculate Gains. The speed loop proportional gain (U.012) and integral
gain (U.013) are calculated from speed response, overshoot damping
percentage, inertia, horsepower, rated RPM, and top RPM.
You can also manually modify U.012 and/or U.013 by clicking on either
parameter and then entering a new value.
Step 4. Click Assign to write the speed loop data to the drive.
5.3.4 Using the Profile Feature To Check Drive Tuning
You can use the speed profile generator to facilitate tuning verification and adjustment
of drive tuning. Once started, the speed profile generator will alternate between two
speed setpoints. You can specify the speed setpoints, acceleration time, deceleration
time, and duration at each setpoint. The speed versus time diagram in the profile
dialog box, as shown in figure 5.6, indicates how the six profile variables are applied.
After starting the profile, the PC Scope feature can be used to monitor torque and/or
speed response to verify or fine-tune the response as desired.
When you select Profile, the Drive Tuning dialog box appears as shown in figure 5.6.
Use the following procedure to check drive tuning.
Step 1. Verify that the load is connected to the motor shaft.
Step 2. Enter values for Speed 1 and 2, Time 1 and 2, Accel and Decel.
