The two passwords protecting the VFD configuration are Parameter Set Display password and Program Disable password. The Parameter Set Display password restricts view- ing. P.nnn parameters above 007 and all H.nnn and R.nnn screens. The password can be accessed at parameter P.006 and will switch between enabled and disabled each time the pass- word 107 is entered. The Program Disable password restricts the changing of the drive parameter set. To enable or disable changes select parameter P.051 and enter the password Set TARGET VFD SPEED to 0% VFD Cooling System Leak Inspection5. Set TARGET VFD SPEED to 100% 5.
