VFD68 Variable Frequency Drives (230 or 460 VAC)
26
The VFD68 drives are RS485, RTU-compliant ModBus® slave devices. For more information, refer to the
VFD68 Variable Frequency Drive Technical Bulletin (Part No. 24-7664-3051).
MON Mode:
Shows motor speed represented as frequency (Hz) or RPM.
RUN, MON, PRM LEDs
The RUN, MON, and PRM LEDs provide drive status and indicate the type of information being displayed on
the operation panel monitor.
RUN LED:
The LED state (on steady, flashing, or flickering) provides information regarding the drive and motor
run status. See Figure 17 for more information.
MON LED:
Indicates that the monitor is displaying the drive’s run status. Press (SET) to scroll through run
frequency, output amperes, and output voltage.
PRM LED:
Indicates that the monitor is set to display parameters and parameter values and allows you to view
and edit parameter values.

condition, press this button
to reset the drive and resume
operation.
Operation mode switchover
Switches between the PU mode and EXT mode.
When using the EXT mode (using an external device
connected to AI1 or AI2, such as a pressure
transducer or control analog output, with a
0–5 V, 0 10 V, or 4 20 mA output), press this key
to light the EXT indication.
