PROFIBUS is an open serial communication standard that enables data exchange between all kinds of automation components. The physical transmission medium of the bus is a twisted pair cable (according to the RS-485 standard). The maximum length of the bus cable is 100 to 1200 meters, depending on the selected transmission rate. Up to 31 stations can be connected to the same PROFIBUS system without the use of repeaters.

Frequently Asked Questions

What is the purpose of a braking resistor with a variable frequency drive?

A braking resistor dissipates regenerated power to prevent the bus voltage from exceeding the drive's rated limit, especially during faster deceleration or overhauling load conditions.

What is the voltage range for ACS150 and ACS355 single-phase applications?

These drives are for single-phase 200-240V applications and are intended for stopping duty only.

What is the voltage range for ACS150 and ACS355 three-phase applications?

These drives are for three-phase 200-240V and 380-480V applications and are intended for stopping duty only.

What is the voltage range for ACS250 single-phase applications?

These drives are for single-phase 100-120V and 200-240V applications and are intended for stopping duty only.

What is the voltage range for ACS250 three-phase UL Type 4X applications?

These drives are for three-phase 200-240V and 380-480V applications and are intended for stopping duty only.

What is the voltage range for ACS250 three-phase applications (non-UL Type 4X)?

These drives are for three-phase 575-690V applications and are intended for stopping duty only.

What is the voltage range for ACS550 three-phase applications?

These drives are for three-phase 200-240V and 380-480V applications and are intended for stopping duty only.

How are Powerohm Type CR resistors constructed?

They feature a nickel-chromium wire helically wound inside a ceramic fixture, placed in a corrosion-resistant aluminum case with high-temperature wire leads.

What is the purpose of braking modules with variable frequency drives?

Braking modules monitor the drive's DC bus and activate external braking resistors to manage regenerated power and improve system performance.

What is the function of the thermal switch in Type GCE and ED enclosures?

The normally closed thermal switch detects resistor temperature overloads and is used to signal an issue.
