IDEC Doesa VF1A Compact AC Drives are high-performance three-phase 380VAC to 480VAC AC drives with enhanced functionality. The built-in advanced features include PID, mechanical brake control, torque control, customizable logic, STO functional safety, and RS-485 Modbus communication. The VF1A AC drives are ideal for use in various applications including fan, pump, and specialized machinery.
The VF1A-PH1 keypad is used for the USB connection with the PC.
The VF1A-DIO digital I/O interface card: For Digital Input (DI), the card can be mounted in the inverter to give the frequency set point by 8 and 12 bits and BCD code(0 to 99.9/0 to 999) and extended 13 digital inputs. For Digital Output (DO), monitoring with 8bit binary code and the digital outputs (extended 8 point) are available.
The VF1A-AIO analog interface card enables the inverter to input analog set-points to the inverter and output analog monitors from the inverter.
The VF1A-RS485 RS-485 communication card provides two RJ-45 connectors for multi-drop connection.
The VF1A-PG1 PG interface (5V) card and the VF1A-PG3 PG interface (12V/15V) card offer speed control, position control, and synchronous drive.
The VF1A-ADP1 mounting adapter for the optional communication card is mounted on the front side of the inverter. It is used from 02A1 to 44A0 type.
The VF1A-ADP2 mounting adapter for the optional communication card is mounted inside the inverter. It is used from 59A0 to 72A0.
The VF1A-ADP3 mounting adapter for the optional communication card is mounted inside the inverter. It is used from 85A0 to 139A.
