KB Electronics KBVF-48 - Manual (Page 11)

• DIVF – Modbus Communication Module (Part No. 9568) – Allows the drive to communicate with
PLCs, PCs, and HMIs with Modbus RTU protocol utilizing a serial communication cable. If a USB
communication cable is required, purchase Part No. 19008.
• Custom Software – All models can be factory programmed for applications which require special
switching, timing, PLC functions, and GFCI operation – contact our Sales Department.

Notes: 1. Models KBVF-27, 29: if a non-isolated signal is used, or if using 0 to ±2.5 thru 0 to ±25 Volts DC or 4 – 20 mA DC signal input, install the
SIVFR Signal Isolator (Part No. 9597). Models KBVF-45, 48: contain built-in signal isolation. 2. Allows the motor to operate up to two times the rated
RPM. Constant motor horsepower will result when operating the drive in the “X2” mode above the motor rated frequency. 3. Dependent on motor per-
formance. 4. Do not operate the drive outside the specified AC line input voltage operating range. 5. Models KBVF-45, 48 only.
