VM_DC_VOLTAGE_SET
Range applied to DC voltage reference parameters
Units
V
Range of [MIN]
0
Range of [MAX]
0 to 1150
Definition
VM_DC_VOLTAGE_SET[MAX] is drive voltage rating dependent. See Table 12-4.
VM_DC_VOLTAGE_SET[MIN] = 0
VM_DRIVE_CURRENT
Range applied to parameters showing current in A
Units
A
Range of [MIN]
-99999.999 to 0.000
Range of [MAX]
0.000 to 99999.999
Definition
VM_DRIVE_CURRENT[MAX] is equivalent to the full scale (over current trip level) for the drive and is given by
Full
Scale Current Kc
(11.061).
VM_DRIVE_CURRENT[MIN] = - VM_DRIVE_CURRENT[MAX]
VM_DRIVE_CURRENT_UNIPOLAR
Unipolar version of VM_DRIVE_CURRENT
Units
A
Range of [MIN]
0.000
Range of [MAX]
0.000 to 99999.999
Definition
VM_DRIVE_CURRENT_UNIPOLAR[MAX] = VM_DRIVE_CURRENT[MAX]
VM_DRIVE_CURRENT_UNIPOLAR[MIN] = 0.000
VM_HIGH_DC_VOLTAGE
Range applied to parameters showing high DC voltage
Units
V
Range of [MIN]
0
Range of [MAX]
0 to 1500
Definition
VM_HIGH_DC_VOLTAGE[MAX] is the full scale d.c. link voltage feedback for the high d.c. link voltage measurement
which can measure the voltage if it goes above the normal full scale value. See Table 12-4.
VM_HIGH_DC_VOLTAGE[MIN] = 0
VM_LOW_UNDER_VOLTS
Range applied to the low under-voltage threshold
Units
V
Range of [MIN]
24
Range of [MAX]
24 to 1150
Definition
If
Back-up Mode Enable
(06.068) = 0:
VM_LOW_UNDER_VOLTS[MAX] = VM_STD_UNDER_VOLTS[MIN]
If
Back-up Mode Enable
(06.068) = 1:
VM_LOW_UNDER_VOLTS[MAX] = VM_STD_UNDER_VOLTS[MIN] / 1.1.
VM_LOW_UNDER_VOLTS[MIN] = 24.
VM_MIN_SWITCHING_FREQUENCY
Range applied to the minimum switching frequency parameter
Units
User units
Range of [MIN]
0
Range of [MAX]
0 to 6
Definition
VM_MIN_SWITCHING_FREQUENCY[MAX] =
Maximum Switching Frequency
(05.018)
VM_MIN_SWITCHING_FREQUENCY[MIN] = 0 for motor control modes, or 1 for Regen mode (subject to the
maximum)
