Emerson unidrive m200 - Final Demand Reference; Zero Frequency Threshold

Menu 3 − Frequency Monitoring and Speed Feedback
Mode: Open‑loop
The drive controls asynchronous machines in open loop control with respect to frequency and current. The open loop asynchronous control is further broken down into vector and fixed boost modes.
Parameter 03.001 Final Demand Reference
Short description Displays the final reference to the frequency controller
Mode Open‑loop
Minimum −VM_FREQ Maximum VM_FREQ
Default Units Hz
Type 32 Bit Volatile Update Rate 16ms
Display Format Standard Decimal Places 2
Coding RO, FI, VM, ND, NC, PT
FinalDemandReference (03.001) shows the fundamental drive frequency demand from the PostRampReference (02.001) and the HardFrequencyReference (03.022) (if enabled).
Parameter 03.005 Zero Frequency Threshold
Short description Defines the threshold for detecting the zero frequency condition
Mode Open‑loop
Minimum 0.00 Maximum 20.00
Default 2.00 Units Hz
Type 16 Bit User Save Update Rate Background read
Display Format Standard Decimal Places 2
Coding RW, BU
If the PostRampReference (02.001) is at or below the level defined by this parameter in either direction ZeroFrequency (10.003) = 1, otherwise ZeroFrequency (10.003) = 0.
