VM_SPEED_FREQ_REF_UNIPOLAR Unipolar version of VM_SPEED_FREQ_REF
Units
Open-loop: Hz
RFC-A, RFC-S: rpm or mm/s
Range of [MIN]
Open-loop: 0.0
RFC-A, RFC-S: 0.0
Range of [MAX]
Open-loop: 0.0 to 550.0
RFC-A, RFC-S: 0.0 to 50000.0
Definition
VM_SPEED_FREQ_REF_UNIPOLAR[MAX] = VM_SPEED_FREQ_REF[MAX]
VM_SPEED_FREQ_REF_UNIPOLAR[MIN] = 0.0
VM_SPEED_FREQ_USER_REFS Range applied to some Menu 1 reference parameters
Units
Open-loop: Hz
RFC-A, RFC-S: rpm or mm/s
Range of [MIN]
Open-loop: -550.0 to 550.0
RFC-A, RFC-S: -50000.0 to 50000.0
Range of [MAX]
Open-loop: 0.0 to 3000.0
RFC-A, RFC-S: 0.0 to 50000.0
Definition
VM_SPEED_FREQ_REF_UNIPOLAR[MAX] = VM_SPEED_FREQ_REF[MAX]
If the second motor map is selected (Pr 11.045 = 1) Pr 21.002 is used instead of Pr 01.007.

VM_STD_UNDER_VOLTS Range applied the standard under-voltage threshold
Units V
Range of [MIN] 0 to 1150
Range of [MAX] 0 to 1150
Definition
VM_STD_UNDER_VOLTS[MAX] = VM_DC_VOLTAGE_SET / 1.1
VM_STD_UNDER_VOLTS[MIN] is voltage rating dependent. See Table 11-4

RFC-A, RFC-S: 0.000 to 3200.000
Definition
VM_SUPPLY_LOSS_LEVEL[MAX] = VM_DC_VOLTAGE_SET[MAX]
VM_SUPPLY_LOSS_LEVEL[MIN] is drive voltage rating dependent. See Table 11-4
VM_SWITCHING_FREQUENCY Range applied the switching frequency parameters
Units
Range of [MIN] 0
Range of [MAX] 6
Definition
VM_SWITCHING_FREQUENCY[MAX] = Power stage dependent
VM_SWITCHING_FREQUENCY[MIN] = 0
