Product Description:

The PCE843-001-F servo drive produced by Pacific Scientific supports a brushless construction and one axis. This drive's operation must be executed in compliance with DIN VDE 0100 specifications. The product's installation in its control cabinet should be carried out by qualified personnel. This device needs permanent hard-wiring because of its high leakage current in the operation period. The unit's motor cable shield is connected with the protective earth. It uses a RS-232 cable for connection to a Windows 95/98/NT PC. This drive's mounting is allowed only on an electrically conductive surface.

The product needs a minimum of 100 mm of unobstructed space above and below it. This device supports convection and forced air cooling modes. The unit operates on a balanced three-phase mains with a voltage rating of 380 VAC to 480 VAC. It is important to install conductive clamps near the drive for the electrical connection of the cables to its panel. This drive needs high-surge KTK-20 Bussmann fuses at the pins 4 to 6 of the TB1 connector. The product's resolver cable must have an external braided shield. This device's connection is recommended with only the manufacturer's cables to avoid adverse performance or reliability issues. The unit needs no motor cable balun for the manufacturer's cables as long as their length does not exceed 10 m. Its option card mustn't be plugged or unplugged when the control power is applied.

This servo drive needs an external hard-wired emergency stop circuit to prevent personnel injury because of the motor motion. The product's powering on must never occur with its cover removed. This device is configured using the 800Tools software. The unit's serial port supports a 9-pin DSUB connector. It can be connected in parallel with other drives to a multidrop master.

Frequently Asked Questions about PCE843-001-F:

Q: What type of power supply must the PCE843-001-F drive be associated with?

A: The PCE843-001-F drive must be associated with a WYE-type three-phase 300 VAC to 480 VAC power supply with an earthed neutral.

Q: Why must ESD protective measures be followed when handling the PCE843-001-F drive?

A: ESD protective measures must be followed when handling the PCE843-001-F drive because it contains electrostatic-sensitive components.

Q: What is the maximum discharge time for the bus capacitors of the PCE843-001-F drive?

A: The maximum discharge time for the bus capacitors of the PCE843-001-F drive is 5 minutes.

Q: How is the cooling of the PCE843-001-F drive done?

A: The cooling of the PCE843-001-F drive is done using forced-air cooling or convection.

Q: What is the maximum ambient operating temperature of the PCE843-001-F drive?

A: The maximum ambient operating temperature of the PCE843-001-F drive is 40 °C.
