Application of Delixi high frequency series inverter in CNC engraving machine

1, the functional requirements of the engraving machine

A) The control mode is selected by VF control, multi-section VF curve.

B) Terminal control is required as the command source. Two-wire terminal control: only one forward command FWD is required. Most of them directly short FWD and COM, so the inverter needs to be in the case of FWD and COM without disconnection. DC braking is available below the set DC braking.

C) The frequency source is analog setting (computer control board output 0~10VDC) or multi-speed setting. It only needs to input frequency command from VF port or multi-stage speed control by multi-function terminal.

D) The maximum running speed is generally 24000r/min, the operating frequency of the converted inverter is 400Hz (high-speed motor of level 2), the lowest cutting speed is 2000r/min, and the frequency range of Delixi high frequency series inverter is 0～1200HZ. Can meet the requirements very well.

E) Acceleration and deceleration time is generally 20~30s according to the customer's own needs. Because the running speed is relatively high, the DC braking function is required for parking, and the inverter with braking unit is required.

F) A fault signal output signal and a fault reset signal are required.

2, the performance requirements of the engraving machine

A) The speed fluctuation is small in the full speed range.

B) The low speed torque is large, which can guarantee low speed cutting.

C) Acceleration and deceleration time is as short as possible.

D) Parking requirements are stable.

Delixi's CDI9100-SH/SCH high-frequency series inverter can do multi-section VF curve, which can control different torque boosts at high and low speeds, so it can meet the requirements of high-speed engraving machine. Specific debugging parameters: (for CDI9100-SH series inverter)

UC Series Bearing

Pillow blocks are advanced applied in places with simple equipment and spare parts, such as agricultural machines, convey system or construction machines. One unit of pillow block consists of deep groove ball bearings with spherical outer rings closed in double sides and a housing made by gray cast iron or punches steel.

A Pillow Block Bearing (Plummer block) is a mounted bearing used to provide support for a rotating shaft with the mounting surface on a parallel line with the axis of the shaft.

Pillow block bearings are generally self-lubricating.

Pillow block bearings are a form of mounted bearing used to provide load support for a rotating shaft axis. The bearing housing mounts to a surface parallel to the shaft axis. Selection of the appropriate bearings can be accomplished based on the shaft size and the radial and thrust load requirements. Pillow block bearings are designed to support a shaft: the mounting surface is on a parallel line with the axis of the shaft. Elongated bolt holes in the base or feet of the unit allow for some adjustment and easy mounting of the pillow block bearing.
