VM_SPEED_FREQ_REF Range applied to the frequency or speed reference parameters
Units
Open-loop: Hz
RFC-A, RFC-S: rpm or mm/s
Range of [MIN]
Open-loop: -550.0 to 0.0
RFC-A, RFC-S: -50000.0 to 0.0
Range of [MAX]
Open-loop: 0.0 to 550.0
RFC-A, RFC-S: 0.0 to 50000.0
Definition
This variable minimum/maximum is applied throughout the frequency and speed reference system so that the
references can vary in the range from the minimum to maximum clamps.
VM_SPEED_FREQ_REF[MIN] = -VM_SPEED_FREQ_REF[MAX].
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 analog 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: 0.00 to 550.00
RFC-A, RFC-S: 0.0 to 50000.0
Definition
VM_SPEED_FREQ_USER_REFS[MAX] = VM_SPEED_FREQ_REF[MAX]
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
