Power supply

The Titan Go Servo Drive is powered from the Supply, shunt and motor connector. An internal isolated DC/DC converter provides the internal logic supply (+24 V_DC) to the circuits as well as regulated 5 V output voltage to supply feedback sensors and I/O. This power supply turns on at 60 V DC bus voltage.

Disconnection recommendations

Please follow the following recommendations:

• The board could be hot during 5 min after disconnection.
• Preferably do not disconnect the supply while having a motor in motion. The back EMF may create dangerous voltages.
• If working with Motion Lab with USB connection, preferably disconnect the drive from the application before disconnecting. This prevents COM port corruption.

Power supply requirements

The choice of a power supply is mainly determined by voltage and current ratings of the power supply. Main requirements of the Titan Go power supply are:

• The voltage should be the targeted for the motor. This means up to 400 V depending on the Titan Go variants. Make sure that the voltage rating of the power supply does not exceed the voltage rating of the motor, otherwise it could be damaged.
• The current should be the one able to provide the phase peak current of the application. This means up to 200 A depending on the Titan Go variants. Make sure that the current rating for the power supply is at least as high as the motor.
• The voltage and current range can be decreased due to the motor requirements.

Further information on how to dimension a power supply for the Ingenia drives can be found here.

Power supply connection

Titan Go power and logic supply are provided through the same terminal. However, the Aux supply connector can be used to supply only the logic with a 24 V power supply (see below).

Twisted cables

Twisted power supply cables are preferred to reduce electromagnetic emissions and increase immunity.

The following picture show the Titan Go supply wiring diagram using a single power supply. The logic supply is internally generated. Note that the minimum power supply voltage is 65 V if single supply is used.

Isolated power supplies

For safety reasons, it is important to use power supplies with full galvanic isolation.

Maximum power supply voltage

Please, note that the maximum nominal power supply voltage is different for each version of the Titan Go:

* Up to 200 V for TTN-xx/200-C-C

* Up to 400 V for TTN-xx/400-C-C

* Up to 800 V for TTN-xx/800-C-C

Do not supply with higher voltage, as the Titan Go could be damaged.

Battery supply connection

Next figure shows a simplified wiring diagram for the Titan Go Servo Drive supplied from a battery. The logic supply is internally generated. Note that the minimum power supply voltage is 60 V if single supply is used.

Motor braking current

Motor braking can cause reverse current sense and charge the battery. Always ensure that the battery can accept this charge current which will be within the Titan Go current ratings.

Maximum power supply voltage

Please, note that the maximum power supply voltage is different for each version of the Titan Go:

* Up to 200 V for TTN-xx/200-C-C

* Up to 400 V for TTN-xx/400-C-C

* Up to 800 V for TTN-xx/800-C-C

Do not supply a higher voltage, as the Titan Go could be damaged.

Dual supply connection

In some cases it could be needed to supply the logic separated from the power. In that cases, the AUX_SUP connector can be used. Next figure shows a simplified wiring diagram for the Titan Go Servo Drive with dual supply. The power consumption of the logic when the power stage is enabled is near 15 W, so the logic power supply must be choses with at least this rated power.

The following picture show the Titan Go supply wiring diagram using a dual power supply. An internal diode connects to the internal +24 V logic supply. Note that the minimum power supply voltage is 10 V if dual supply is used.

Next figure shows a simplified wiring diagram for the Titan Go Servo Drive supplied from two batteries. Note that the minimum power supply voltage is 10 V if dual supply is used.

Maximum power supply voltage

Please, note that the maximum power supply voltage is different for each version of the Titan Go:

* Up to 200 V for TTN-xx/200-C-C

* Up to 400 V for TTN-xx/400-C-C

Do not supply a higher voltage, as the Titan Go could be damaged.

Connection of multiple drives with the same power supply

When different servo drives are connected to the same power supply, connect them in star topology for reducing cable impedance and common mode coupled noise. That is, connect each drive to the common supply using separate wires for positive and return.

Power supply wiring recommendations

Wire section

The minimum wire section is determined by the current consumption and the allowed voltage drop across the conductor. It is preferred to use wide section stranded wires to reduce impedance, power losses and ease the assembly. Following table indicates recommended wire sections:

In case of using buss bars please take care not to exceed the terminal torque.

Wire length

• The distance between the Titan Go Servo Drive and the power supply should be minimized when possible. Short cables are preferred since they reduce power losses as well as electromagnetic emissions and immunity.
• For best immunity use twisted and shielded 2-wire cables for the DC power supply. This becomes crucial in long cable applications.
• Avoid running supply wires in parallel with other wires for long distances, especially feedback and signal wires.

Supply protection

It is strongly recommended to use an over-current protection between the drive and the DC power supply. Both a  fuse or a DC circuit breaker can be used. Class B or Z would be preferred, typically rated for semiconductor, control or photovoltaic applications. Take the following as suggested parts:
