Final Adjustments - Reliance electric GV3000/SE Instruction Manual

Final Adjustments

1. Turn OFF, lock out or tag input power to the controller.
• Connect the application load to the motor.
• Turn power ON.
• Press controller START key.
• Check if vibration of the machinery is occurring at any frequency.
2. In case of vibration, enable Avoidance Frequency function (H.009) and set Midpoint and Band of
Avoidance Frequency(ies) (H.010 to H.015).
3. Check the brake away behavior when starting the machine. For multimotor application the Torque
Boost Voltage (H.003) can be optimized for the machine.
4. Slip Compensation (H.004) can be trimmed to reach same RPM at Maximum Hz speed reference at
load and no-load conditions (if applicable).
5. DC-Braking Adjustments
DC Braking (H.005) can be enabled, if Stop Type (P.025) is set to 'Ramp to Rest', to avoid
continuous rotation of machinery. This function will not provide the holding torque as a mechanical
brake! If enabled, you should follow the adjustment procedure with parameters H.006 to H.008.
• Enter in H.006 for DC Braking Start Frequency a value more than two times Slip Frequency.
• Increase with H.007 the current until fault trips by OC, OCA, OCb or PUo occur.
Then decrease H.007 approx. 10% - 20% below this value.
• Enter a long Braking Time (H.008) depending on the inertia (e.g. 10 sec) and then reduce the time
until the stop is optimized.
• Repeat this adjustment and try to vary H.007. It could be necessary to change H.007 and H.008
several times to reach the best configuration for your application.
6. Start into rotating motor with Sync. Direction (H.016) may be activated, if the application requests a
START command to be initiated at rotating machinery (e.g. restart during coast to rest).
7. The Fault Auto Reset function can be selected to restart the drive after faults automatically. Refer to
P.043...P.044 for adjustment.
8. When operation is satisfactory:
• Make a note of final parameter settings in copies of tables in Section 8.
• Eventually disable Parameter Programming (P.051).
• Replace the controller cover (if removed) and secure.
• Eventually turn OFF, lock out and tag power to the controller.
