RELIANCE ELECTRICI GV3000/SE AC General Purpose (Volts/Hertz) and Vector Duty Drive Version 6.06

Step 4: Set the maximum speed of the motor (U.017)

For weak magnetic applications, a value higher than the rated speed can be set; Otherwise, it should be consistent with U.005.

Step 5: Adjust the speed loop parameters

U. 012 Speed loop proportional gain: affects dynamic response, and excessive gain can easily cause oscillation.

U. 013 Speed loop integral gain: usually does not require adjustment, high inertia loads can be adjusted appropriately.

Step 6: Trial operation and direction verification

Similar to the V/Hz process, conduct a low-speed start test to ensure correct steering.

Detailed Explanation of Parameter Programming

3.1 Parameter menu structure

First menu: Common general parameters (P.000-P.006), no password required.

Second menu: Advanced parameters, including:

General parameters (P.007 – P.099)

V/Hz parameters (H.000-H.022)

Vector parameters (U.000-U.048)

RMI board parameters (r.001 – r.066, optional)

Error log (Err)

3.2 Key Parameter Function Description

P. 025 Stop Type: 0=Free Parking, 1=Slope Parking.

P. 040 Motor Overload Enable: Enable electronic thermal overload protection, similar to a thermal relay function.

P. 047 Carrier frequency: selectable from 2, 4, and 8 kHz, affecting motor noise and driver output capability.

P. 054 Level Induction Start Enable: Suitable for remote control, the start signal is level hold rather than edge trigger.

U. 024 High DC Bus Fault Avoidance: After activation, the driver attempts to adjust the bus voltage to avoid faults caused by regenerative energy.

3.3 Programming Security and Password Protection

Keyboard parameter modification can be disabled through P.051, with password "26". P. 006 is used to protect access to the second menu, with a password of "107". The password function only restricts local keyboard modification and does not affect parameter writing through serial port or network.

Monitoring and operation interface

4.1 Keyboard and Display Layout

The keyboard contains 9 keys:

Program: Switch between monitoring/programming mode.

AUTO/MAN: Switch between automatic (external) and manual (local) speed references.

▲/▼: Adjust parameter values or reference speed.

ENTER: Confirm the selection or save of parameters.

START, STOP/RESET, RUN/JOG, FORWARD/REVERSE: Used for local control.

4.2 Monitoring Mode Display Content

Can display the following real-time data in a loop:

Speed (scalable, P.028 setting)

output voltage

output current

output frequency

power (kW)

Torque (specifically for vector control)

4.3 Status indicator lights

RUNNING: The motor is powered on.

Remote: The control source is remote.

AUTO: The speed reference comes from external sources.

FORWARD/REVERSE: Motor direction indicator.

Program: In programming mode.

PASSWORD: Parameter modification is disabled.

Fault diagnosis and error logs

5.1 Alarm and fault codes

Alarm code: Flashing display, driver continues to run (e.g. "LIL" indicates low input voltage).

Fault code: Flashing display, driver shutdown (e.g. "OL" indicates motor overload).

Fatal Fault: Starting with "F", it usually indicates a hardware failure of the regulator board.

5.2 Error log access

By entering the "Err" menu through programming mode, you can view the last 10 fault records, including the occurrence time (based on the 24-hour clock) and date (based on the 248 day counter). The logs can be cleared all at once through the "CLr" option.

5.3 Common Fault Handling

OC/OCA/OCb: overcurrent, check acceleration time, load inertia, and current limit settings.

HU: High DC bus voltage, extending deceleration time or installing braking resistors.

LU: Low DC bus voltage, check the input power supply or adjust the voltage drop time of P.042.

OL: Motor overload, check the rated current parameters of the motor (H.002 or U.004).

SF: Self tuning failed, check the specific reason for U.009.

Advanced features and option configuration

6.1 Network Communication Options

Support network cards such as DeviceNet, ControlNet, PROFIBUS, etc., configure network addresses, reference sources, and response methods through P.060-P.069.

6.2 Outer Loop Control (OCL) Function

Suitable for closed-loop applications such as tension and position, configured with feedback sources, PID parameters, and adjustment ranges through U.040-U.448.

6.3 Braking and Energy Management

Dynamic braking: Configure braking resistors through H.017 to absorb regenerative energy.

DC braking: Set the starting frequency, current, and time of braking through H.005-H.008.

Frequency avoidance: Set the resonance frequency range to be skipped through H.009-H.015.
