Transport Racks are designed for use as internal racks for delivery and cube vans. Mounting pads are attached so racks can be bolted directly to van's floor. These Racks feature full rubber lining on all contact surfaces, durable hot-dipped galvanized finish, and mounting pads for bolting directly to truck or van beds. Each rack includes four rubber lined hold down bars with quick release ratchet straps to secure the load whether it's glass, doors or windows. Each rack ships knocked down to save on freight, so some assembly is required.

(I) Mechanical transmission failure
Treatment method: Check whether the belt drive is broken or whether the machine is in neutral.
(b) Phase loss or inversion of the three-phase power supply to the main shaft
Treatment method: Check the power supply and replace any two power cords.
(c) Circuit Connection Errors
Treatment method: Refer to the circuit connection manual to ensure that the connection is correct.
(D) The system does not have a corresponding spindle control signal output
Processing method: Use a multimeter to output the signal from the system. If there is no spindle control signal output, replace the relevant IC component or send it to the factory for repair.
(five) The system has a corresponding spindle signal output, but the power supply circuit and control signal output circuit is open circuit or the components are damaged
Treatment method: Use a multimeter to check the power supply circuit between the system and the spindle motor, whether the signal control circuit is open circuit; whether the contact of each connection is bad; if the AC contactor and the DC relay are damaged, check the thermal relay. It is not overcurrent; check whether the insurance is burned.
Second, the spindle with frequency converter does not turn
(A) caused by mechanical transmission
Treatment method: Check whether the belt drive is broken or whether the machine tool is in neutral.
(b) Phase loss of the three-phase power supply to the main shaft
Treatment method: Check the power supply and replace the two power cables.
(C) The inverter control parameters of the control system are not turned on
Processing method: Check the parameter manual to understand the frequency conversion parameters and change them.
(4) The line connection between the system and the inverter is incorrect
Treatment method: Check the wiring instructions of the system and the inverter to ensure that the connection is correct.
(E) The analog voltage output is abnormal
Treatment method: Use a universal meter to check the analog voltage of the system is not normal, check the analog voltage signal line connection is not correct or bad contact, the analog voltage received by the frequency conversion is not matched.
(6) Severely open circuit or damaged components
Treatment method: Check whether the connection of the main shaft power supply is reliable or not, whether the circuit is open circuit, whether the DC relay is damaged, and whether the fuse is burned.
(7) The inverter parameters are not adjusted well
Processing method: Inverter contains control mode selection, which is divided into inverter panel control spindle mode, NC system control spindle mode, etc. If you do not select NC system control mode, you cannot use the system to control the spindle, modify this parameter; check relevant parameters The setting is not reasonable.
Third, the spindle with electromagnetic coupling does not turn
There is no voltage supply to the electromagnetic clutch coil, so that the transmission gear can not be closed, resulting in the spindle can not be turned; the short circuit of the coil may also cause the spindle to not work properly.
Treatment method: Check the power supply of the clutch coil is not normal; the fuse is not damaged; check the clutch coil is not damaged, replace the components in line with the specifications.
Fourth, the spindle with brake coil does not turn
Frequent start and stop of the spindle, so that the brakes also start and stop frequently, resulting in the control of the brake AC contactor damage, so that the brake coil has been energized to lock the spindle motor can not rotate the spindle.
Treatment method: Replace the AC contactor that controls the brake.
V. The spindle speed controlled by the inverter is not controlled
(A) The motherboard does not have inverter function
Processing method: Replace the motherboard with inverter function.
(II) The system analog voltage has no output or is connected to the inverter.
Treatment method: First check whether the system has analog voltage output. If not, it is a system fault. If yes, check whether the circuit is open circuit.
(C) System and inverter connection error
Treatment method: Check the connection manual and check the connection.
(4) System parameters or inverter parameters are not set
Processing method: Open the system variable frequency parameters and adjust the inverter parameters.
(E) Incorrect shaft speed display due to system software
Processing method: When the inverter changes from S500 to S800, but the display is still S500, it is necessary to use G04 delay during programming, and the system software needs to be improved.
Sixth, the spindle without frequency conversion (shift spindle) speed is not controlled
(A) The system does not have control signal output of S01-S02
Treatment method: check whether the system has shift control output, no system failure, replace the IC or send factory maintenance.
(b) Cable fault
Treatment method: The system has a shift control signal output, check whether the connection is open circuit or poor contact, check whether the DC electrical or AC contactor is damaged.
(III) Damage or short circuit of the spindle motor
Treatment method: Check the spindle motor.
(d) The machine has not been posted
Treatment method: hang a file.
Seven, spindle without brake
(I) Abnormal brake circuit or damage to strong circuit components
Treatment method: Check the bridge pile, fuse, AC contactor is not damaged; check whether the strong electric circuit is broken.
(b) The braking time is not long enough
Treatment method: Adjust the braking time parameter of the system or inverter.
(C) No brake signal output
Treatment method: Replace internal components or send factory for repair.
(D) The inverter control parameters are not adjusted well
Treatment method: Check the inverter instruction manual and set the inverter parameters correctly.
Eight, stop immediately after the spindle starts
(a) The system output pulse time is not enough
Processing method: Adjust the system's M code output time.
(b) The inverter is in jog
Processing method: Refer to the manual of the inverter and adjust the parameters.
(c) Damage to the control elements of the main shaft circuit
Treatment method: Check the contact points on the circuit is not good, check the DC relay, AC relay is not damaged, resulting in the contact is not self-locking.
