Aerotech NDrive HP 10/20/30 Maintenance and Replacement

Shutdown replacement and selection process

When replacing discontinued NDrive or other brand servo modules, it is recommended to follow the following sequence:

Record original module parameters: model, peak/continuous current, bus voltage, AC input, feedback type, communication interface, I/O quantity, PSO axis number MXH/MXU、 Brake output, ESTOP logic, size, and heat dissipation.

Match motor: Confirm brushless/brushed/stepper, pole pairs Hall、 Encoder resolution, rotation or Inductosyn. If the original system uses a rotary converter, HP needs to choose - RDP; If using an analog sine encoder, choose - MXH.

Confirm power supply and regeneration: HP supports 240 VAC single-phase/three-phase, optional - AUXPWR, - S shutt, -3P, - HS heat sink, and - FAN fan. Low bus voltage or maintaining logic power supply requires AUXPWR.

Confirm network: FireWire topology, S2 channel number, controller axis mapping. When Ethernet I/O is required, select - ENET.

Confirm I/O and PSO: When standard I/O is insufficient, select - IOPSO or - IOPSOH; Dual axis/three-axis laser trigger selection - DUALPSO/- TRIPLEPSO; PSO output optoelectronic isolator selects PSOOPTO1-4 based on speed/voltage.

Mechanical and cooling: The HP weighs approximately 5.0-5.4 pounds and requires 1 inch of free air space. The ambient temperature should not exceed 40 ° C, and the chassis temperature may exceed 75 ° C. Be careful of burns.

Power on test: Do not connect the motor first, check the LED, FireWire, ESTOP, and logic power supply; Connect the motor for low-speed testing of phase, feedback direction, limit, and PSO; Finally, gradually load and check the current, temperature, and tracking error.

If the original device uses CP or MP series, attention should be paid to the differences in HP: HP supports larger currents, rotary converters Ethernet、 Multi axis PSO and - IOPSOH, but with higher volume and cost. CP is cost sensitive, MXU and PSO are mutually exclusive; MP is an ultra compact DC input; CL/HL is a linear power level. When replacing, it is not enough to only look at the installation size and current. Feedback, communication, and functional options must be checked.

FAQ

How to choose NDrive HP10, HP20, HP30?

Select based on peak and continuous current: HP10 is 10/5 A, HP20 is 20/10 A, and HP30 is 30/15 A. It is also necessary to verify the bus voltage, power, and heat dissipation.

Can we directly replace other brands of servo drives?

It cannot be judged solely based on current and size. It is necessary to verify the motor type, feedback, commutation, FireWire network, I/O, PSO, ESTOP, and regeneration processing.

Does HP support rotation?

Support, the - RDP rotary input option needs to be selected, providing single/dual channel, 10/7.5/5 kHz carrier frequency.

Can MXH and PSO be used simultaneously?

HP's MXH supports PSO and real-time orthogonal output, but attention should be paid to the 5 MHz tracking limit of multi axis PSO and MXH clock settings.

How to wire ESTOP?

TB201 input 5-24 V, driven by an external fail safe emergency stop circuit, with current limiting resistors in series if necessary, and noise suppression added.

How to connect a multi axis system?

Through FireWire star daisy chain, up to 32 axes, with a single chain of 16 drivers, each driver is assigned a unique channel number using S2.
