Quick setup and diagnostics with real text display, onboard PLC and safety inputs
Control Techniques’ Unidrive M400 variable frequency AC drive (VFD) minimizes downtime with an optional plain-text, multi-language backlit LCD keypad enabling rapid setup and clear diagnostic help.
The integrated PLC can execute a substantial range of sequencing and logic programs. Unidrive M400 has an impressive onboard I/O count, dual Safe Torque Off (STO) inputs, and can accommodate a single SI option module for additional flexibility.
The SI module has options for industry standard fieldbus, Ethernet, and expanded I/O. Additionally, an AI option slot is available for parameter cloning, 24V backup, and Modbus RTU communication options. A CI-485-ADAPTOR is also available to provide additional Modbus RTU communications in place of the optional keypad.
