Variable Frequency Drive (VFD)
Keypad
The VFD keypad consists of a display, four control but-
tons, and a joypad with four arrow keys. See F
VFD Display
The VFD display has two rows.
The upper row (A) displays either the drive status (run is
shown) or the parameter being viewed, in the format
XX.XX (for example, 20.05). In this manual, parameters
are referred to as Pr (for example Pr 20.05).
The lower row (B) displays the parameter value (152 is
shown) or a trip code.
Table 1 shows some examples of drive status codes.
Refer to the User’s Guide by Control Techniques for the
full list.
