Distribution Cache Shipping Info and Options

Shipping Carriers: Here at Distribution Cache we ship using UPS, FedEx, DHL, or TNT. In most cases we get very competitive rates based on our volume and will be happy quote shipping cost to your location upon request. We also know that many customers would prefer to ship collect on their own account numbers and welcome this option.

Shipping Blind: We recognize that many of our customers intend to re-sell the product to their end user. We respect our customer’s relationships with their clients and offer blind shipping as an option to ensure that the package arrives in the most clandestine way possible.

Shipping Process: We take pride in the way we package your order and spare no cost in making sure that it arrives safely at your facility. In the case of new parts, we are always sure to package the factory box inside another larger box for safe transit. For reconditioned parts we often use Distribution Cache customized packaging that is specially made to protect the products from the bumps and falls present during shipment.

Shipping Options:

Next Day Air Early AM - This service is the fastest overnight delivery option available. For most locations the package will be guaranteed by 8:30AM.

Next Day Air – This service guarantees delivery by 10:30AM and is the most frequently used option for overnight shipments.

Next Day Air Saver – This cost saving overnight alternative guarantees delivery by 3PM the next day.

2nd Day Air – For domestic shipments that would take 3-5 days if shipped via Ground, sometimes having the order in 2 days is a great way to go

Ground – Ground is the most inexpensive shipping option provided. Please ask if we are doing a “free domestic ground” shipping promotion on your order. We often provide free ground shipping on larger orders.

Emergency Courier – At times we can help work with a courier service to get the part to your facility during downtimes scenarios. We prefer that the customer sets up the courier but we can be there to make sure the product is handed off to the driver. Please give us a call to see if this is an option on your order.

Please Note: Products listed as “ships today” can ship same-day if an order is placed before 4PM. For larger drives and motors we ask that notification for same-day shipments be provided by 2PM at the latest. For any products listed as “ships in 3-5 days”, please give us a call to see if this can be expedited.

What is a GV3000 drive?

The GV3000/SE AC drive is a PWM (Pulse-Width-Modulation) drive that supplies vector and general purpose regulation for a broad array of uses.

Using vector regulation, high dynamic response can be provided by the drive, keep total rated motor torque to zero rate, and just control motor speed in both ways. The drive can supply this functionality either with encoder feedback (flux vector control or FVC) or without (sensorless vector control or SVC).

Using general purpose (volts/hertz or V/Hz) regulation, the drive is satisfied for a wide array of applications requiring flexible speed control of motors.

What are NEMA Enclosures for GV3000 drives?

Each of the GV3000/SE Power Modules have one of the subsequent NEMA evaluations:

• NEMA1: Vented. Without removing the cover includes a communicating access door which allows access to the communication interface. Thought for General purpose indoor programs.

• NEMA 4X/12: Not Vented. Provided with keypad and foundation gaskets. Intended to be used in indoor environments that need a watertight/dust-tight enclosure. An enclosure with this particular NEMA evaluation encompasses both evaluations (4X and 12).

• NEMA 12: Intended for use in indoor environments that need a dust-tight/ drip-tight enclosure.

What do Regulator Boards do?

GV3000/SE drive regulation is done by a microprocessor on the Regulator board. The parameters adjust drive operation. The Regulator board accepts an external speed reference signal and electricity circuit feedback signals, along with information from an encoder that's connected to the motor when set up for FVC regulation. The Regulator board supplies:

• PWM gating signals to the IGBT power apparatus

On the basis of the output signal of the control loop, PWM gating signals are sent by the regulator through the Present Feedback board to disjunct motorists on the Gate Driver board. These drivers change the Insulated Gate Bipolar Transistors (IGBTs), creating a pulse-width-modulated (PWM) waveform that corresponds to the rate (FVC regulation) or frequency (volts/hertz regulation) benchmark. The IGBTs may be changed at either a 2, 8 or 4 kHz carrier frequency.

• Form B and A contacts for drive status indicators The Type A and B contacts are under control of the user via programmable parameters. B transition or a Type A can indicate drive status. The contacts are made accessible through the terminal strip and are rated for 5 amps resistive load at 250 VAC/ 30 VDC.

• Show information for a four-character screen and fourteen gauge LEDs The four-character screen is utilized to show parameter values drive parameters, and fault codes. The fourteen single LEDs indicate mode and drive status, in addition to identifying drive output signals whose values are shown on the four-character screen.

• An analog output signal The analog output signal is a scaled voltage (0-10 VDC) or current (4-20 mA) signal proportional to either motor speed (RPM) or motor torque or current (%TORQUE). The current signal choice (via jumper J17) needs a power supply for operation. The electricity may be sourced from the encoder terminals (4 and 9) or from an outside 15V power supply. See table 7.8, terminals 10 and 11, for more info. The analog output signal can be found through the terminal strip.

• A snubber resistor braking signal The Regulator board supplies a signal to be used by an elective snubber resistor braking kit. The signal can be found through the terminal strip.

What Test Equipment is Needed to Troubleshoot a GV3000 drive?

A multimeter will likely be required to make resistance tests and to quantify DC bus voltage. Note that dedicated troubleshooting evaluation points aren't supplied.

What are Common Drive Alarms and Faults?

The drive will show fault and alarm codes to help in troubleshooting when a problem develops during self-tuning or drive operation.

When an alarm state happens, the drive will continue to go as well as a 2- or 3-digit alarm code will flash on the screen.

If a mistake happens, the drive will coast-to-rest stop as well as a 2- or 3-digit fault code will flash on the screen.

Consult with the GV3000/SE Applications Startup and Reference manual to find out more on faults and drive alarms.

How do I Check That DC Bus Capacitors are Discharged on a GV3000 drive?

After input power was disconnected, the GV3000/SE drive's DC bus capacitors retain hazardous voltage. Before touching any internal parts perform these measures: ATTENTION: DC bus capacitors retain hazardous voltages after input power has been disconnected. After disconnecting input power, wait five (5) minutes for the DC bus capacitors to discharge and then check the voltage with a voltmeter to ensure the DC bus capacitors are discharged before touching any internal components. Failure to observe this precaution could

Step 1. Turn off and lock out AC input signal power. Wait five minutes.

Step 2. Remove.

Step 3. Check that there's no voltage in the input power terminals of the drive.

Step 4. Assess the DC bus potential using a voltmeter in the DC bus power terminals while standing on a nonconductive surface and wearing insulated groves (600 V).

Step 5. Once the drive was serviced, reattach the cover of the drive.

Step 6. Reapply AC input signal power.

How do I Check Out Power Module with Input Power Off?

Make use of the following procedure to look over off the drive's Power Module circuitry with power:

Step 1. Turn off and lock out input signal power. Wait five minutes.

Step 2. Remove.

Step 3. Check that there's no voltage in the input terminals of the drive.

Step 4. Examine the DC bus potential with a voltmeter as described in section 9.3 to ensure that the DC bus capacitors are discharged.

Step 5. Disconnect the motor from the drive.

Step 6. Check all AC line and DC bus fuses.

Step 7. If a fuse is open, make use of a multimeter to look over output signal IGBTs and the input signal diodes. See table 1.1. Note that the drives don't have replaceable transistor modules: the whole drive has to be replaced if a transistor malfunctions.

Step 8. Reconnect the motor to the drive.

Step 9. Reattach the drive's cover.

Step 10. Reapply input signal power.
