4.8 Multi-State Value (MSV) Object Descriptions

Object MSV-1: Speed Source Selection

This object mimics the functionality of the SPEED SOURCE key on the drive keypad. It
is used to determine whether the drive will get its speed/setpoint reference from Drive
Parameter #24 (Auto Source) or Drive Parameter #29 (Hand Source).

This object allows the user to toggle between OPEN loop speed control and CLOSED loop
PID control when PID mode is ENABLED (refer to MSI-3). The ability to command this
object through the LAN is dictated by Drive Parameter #30 (Control) and the drive HOA
(refer to MSI-4)

For more information on SPEED SOURCE, refer to the MCH Installation and Operation Manual (MH01).
