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

= 1) Pr
21.002
is used instead of Pr
01.007
.

VM_STD_UNDER_VOLTS
Range applied to 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 12-4
VM_SUPPLY_LOSS_LEVEL
Range applied to the supply loss threshold
Units
V
Range of [MIN]
0 to 1150
Range of [MAX]
0 to 1150
Definition
VM_SUPPLY_LOSS_LEVEL[MAX] = VM_DC_VOLTAGE_SET[MAX]
VM_SUPPLY_LOSS_LEVEL[MIN] is drive voltage rating dependent. See Table 12-4
VM_SWITCHING_FREQUENCY
Range applied to the maximum switching frequency parameters
Units
User units
Range of [MIN]
0
Range of [MAX]
0 to 6
Definition
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)
