FENA-21
The FENA 21 DualPort module supports Three protocols Modbus-TCP, EtherNet/IP, and the PROFInet IO RT network. The Modbus-TCP protocol is simply the Modbus protocol used on top of Ethernet-TCP/IP. Modbus-TCP is an open Industrial Ethernet network which has been specified by the Modbus-IDA User Organization. EtherNet/IP is based on the Common Industrial Protocol (CIP), which is also the framework for both the ControlNet and DeviceNet network protocols. PROFInet IO RT is an open network based on the PI Organization standard.Frequently Asked Questions
What is the power and voltage range for ABB standard drives?
The drives support 3-phase power with ranges of 208-240V (0.75-100Hp), 380-480V (1-550Hp), and 500-600V (1.5-150Hp).
Does the drive have built-in serial communication?
Yes, the drive has built-in Modbus RTU protocol for serial communication via RS 485.
What is the operating frequency range for the drives?
The input power frequency range is 48 to 63 Hz, and the motor connection frequency can be set from 0 to 500 Hz.
What product compliance and certifications does the ACS550 series have?
The drives have UL, cUL, CSA, CE, C-TICK, and GOST-R approvals, and are certified to ICC AC-156 for seismic activity.
What types of control connections are available?
There are two analog inputs (voltage/current), two analog outputs (current), and six digital inputs available.
What NEMA protection classes are available for the ACS550 drives?
The drives are available in UL Type 1, 12, or 3R (NEMA 1, 12, or 3R) enclosures depending on the specific model.
What are the acceleration and deceleration time limits?
Acceleration and deceleration times can be set between 0.1 to 1800 seconds.
What are the environmental operating temperature limits?
The ambient temperature range is 15 to 40°C (5 to 104°F), and derating is required from 40 to 50°C (104 to 122°F).
