VM_SPEED_FREQ_REF_UNIPOLAR[MIN] = 0.0
Identifier VM_SPEED_FREQ_USER_REFS
Description Range applied to analogue reference parameters
Units
Open-loop: Hz
RFC-A, RFC-S: rpm or mm/s
Range of [MIN]
Open-loop: -550.00 to 550.00
RFC-A, RFC-S: -50000.0 to 50000.0
Range of [MAX]
Open-loop: 0.0 to 550.00
RFC-A, RFC-S: 0.0 to 50000.0
This variable maximum is applied to Analogue Reference 1 (01.036) and Analogue Reference 2 (01.037). It should be noted that in Open-loop mode the
analogue reference parameters have two decimal places.
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).

VM_STD_UNDER_VOLTS[MIN] 175 330 435 435
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.
Voltage level 200V 400V 575V 690V
VM_SUPPLY_LOSS_LEVEL[MIN] 205 410 540 540
Identifier VM_SWITCHING_FREQUENCY
Description Range applied to the maximum switching frequency parameters
Units User units
Range of [MIN] 0
Range of [MAX] 0 to 6
VM_SWITCHING_FREQUENCY[MAX] = Power stage dependent
VM_SWITCHING_FREQUENCY[MIN] = 0 for motor control modes, or 1 for Regen mode (subject to the maximum)
