VM_SPEED_FREQ_REF_UNIPOLAR[MIN] = 0.00
Identifier VM_SPEED_FREQ_USER_REFS
Description Range applied to analogue reference parameters
Units Hz
Range of [MIN] -550.00 to 550.00
Range of [MAX] 0.00 to 550.00
This variable maximum is applied to AnalogueReference1 (01.036), AnalogueReference2 (01.037) and KeypadReference (01.017).
The maximum applied to these parameters is the same as other frequency reference parameters.
VM_SPEED_FREQ_USER_REFS [MAX] = VM_SPEED_FREQ_REF[MAX]
However the minimum is dependent on NegativeReferenceClampEnable (01.008) and BipolarReferenceEnable (01.010).

Note - Parameter 11.045 is not available on M100/M101 and so only the Motor 1 parameters are relevant.
Identifier VM_SUPPLY_LOSS_LEVEL
Description Range applied to the supply loss threshold
Units V
Range of [MIN] 0 to 1150
Range of [MAX] 0 to 1150
VM_SUPPLY_LOSS_LEVEL[MAX] = VM_DC_VOLTAGE_SET[MAX]
VM_SUPPLY_LOSS_LEVEL[MIN] is drive voltage rating dependent. See the table below.
