Troubleshooting:
Troubleshooting the Motormaster® V control requires a
combination of observing system operation and VFD display
information. The MMV should follow the 4-20 mA signal
from the ComfortLink™ controls.
The speed command from the ComfortLink controls can be
monitored in 2 ways:
1. Variables VH.PA, VH.PB in the "outputs" submenu of
ComfortLink control — given as a percentage of 4 to
20 mA range.
APPENDIX I (cont)
Table 2: Program Parameters for the 4 Operating Modes:
DESCRIPTION
2. P56 in Motormaster V shows 4-20 mA input in percent of
maximum input.
Due to the variable definitions of each controller, Table 3
shows a cross-reference:
