AEROTECHNdrive HP 10/20/30 USER'S MANUAL

2.3. Power Connections

The Ndrive HP may powered by one or two separate AC voltages. One for motor bus power and optionally a second for control power, as described in the following two subsections. If the optional control power input is present, it must be powered.

2.3.1. Control Power Connections (TB101)

The -AUXPWR option allows the Ndrive HP to remain operational when the motor power is removed, such as when an external emergency stop circuit is required. If the Ndrive HP was purchased with the -AUXPWR option, a separate AC input (TB101) has been included on the amplifier. The internal power supply of the Ndrive HP requires a minimum of 85 VAC input to operate properly. The figure below shows the connection to the separate AC power board. The connection is made to the AC input board with a three terminal connector (Aerotech Part #ECK00213), provided. See Section 2.4. for various typical AC wiring options. TB101 is also typically utilized when an emergency stop circuit is present. See Section 2.10 for a typical ESTOP sense input wiring configuration.

The AUXPWR input is an option that, if present, must be powered. It is typically used when the AC bus input power is less than 85 VAC at TB102 AC1, AC2 (or AC3). TB101 is also typically utilized when an emergency stop circuit is present. Optional Supply Connections to AL1, AL2 and the Protective Ground should be at least 1.02362 mm (#18 AWG) wire rated @ 300 V (3 Amp external fusing may be required for AL2, AL1 is fused internally at 3 Amps).

2.3.2. Motor Power Connections (TB102)

The three-phase motor terminal connections are made at connections A, B, and C. Motor Connections ØA, ØB, ØC and its Protective Ground should be made with 1.62814 mm (#14 AWG) wire rated at 300 V. Motor frame and shield connect to (ground). Input power to the Ndrive is made at the AC1 and AC2 terminals with earth ground connected to (ground). A three-phase power input is also available (AC3, requires 3 Phase Option). Connections at AC1, AC2 and AC3 and its Protective Ground should be made with 1.62814 mm (#14 AWG) wire rated at 300V

2.3.3. 40/80 VDC Power Transformers The TV0.3-56 power transformer is an optional accessory for the Ndrive HP. The transformer allows the generation of 56 VAC from a 115 VAC and 230 VAC source respectively. When rectified by the Ndrive HP, 56 VAC yields an 80 VDC power bus. The TV0.3-28 power transformer is an optional accessory available for the Ndrive HP. This transformer allows for the generation of 28 VAC from a 115 VAC or 230 VAC source, respectively. When rectified by the Ndrive, 28 VAC yields a 40 VDC power bus. The following three figures illustrate the six combinations available for both AC input voltages and all three DC bus voltages, as well as the use of the -AUXPWR option. A TM3 and TM5 transformer package is also available to power up to four Ndrives, providing 300 or 500 watts of power.
