HVAC Drive H300 199
Issue Number: 3
VM_DC_VOLTAGE Range applied to parameters showing DC voltage
Units V
Range of [MIN] 0
Range of [MAX] 0 to 1190
Definition
VM_DC_VOLTAGE[MAX] is the full scale DC bus voltage feedback (over voltage trip level) for the drive. This level is
drive voltage rating dependent. See Table 11-4
VM_DC_VOLTAGE[MIN] = 0
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 11-4
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) or Kc value 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 DC bus voltage feedback for the high DC bus voltage measurement
which can measure the voltage if it goes above the normal full scale value. This level is drive voltage rating dependent.
See Table 11-4
VM_HIGH_DC_VOLTAGE[MIN] = 0
VM_LOW_UNDER_VOLTS Range applied 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.
