10.1 Parameter ranges and Variable minimum/maximums:
Some parameters in the drive have a variable range with a variable minimum and a variable maximum values which is dependent on one of the
following:
• The settings of other parameters
• The drive rating
• The drive mode
• Combination of any of the above
The tables below give the definition of variable minimum/maximum and the maximum range of these.
VM_AC_VOLTAGE Range applied to parameters showing AC voltage
Units V
Range of [MIN] 0
Range of [MAX] 0 to 930
Definition
VM_AC_VOLTAGE[MAX] is drive voltage rating dependent. See Table 10-4
VM_AC_VOLTAGE[MIN] = 0
VM_AC_VOLTAGE_SET Range applied to the AC voltage set-up parameters
Units V
Range of [MIN] 0
Range of [MAX] 0 to 765
Definition
VM_AC_VOLTAGE_SET[MAX] is drive voltage rating dependent. See Table 10-4
VM_AC_VOLTAGE_SET[MIN] = 0
VM_ACCEL_RATE Maximum applied to the ramp rate parameters
Units s / 100 Hz, s/1000 Hz, s/Max Frequency
Range of [MIN] Open-loop: 0.0
Range of [MAX] Open-loop: 0.0 to 3200.0
Definition
A maximum needs to be applied to the ramp rate parameters because the units are a time for a change of speed from
zero to a defined level or to maximum speed. If the change of speed is to the maximum speed then changing the
maximum speed changes the actual ramp rate for a given ramp rate parameter value. The variable maximum
calculation ensures that longest ramp rate (parameter at its maximum value) is not slower than the rate with the defined
level, i.e. 3200.0 s/100 Hz.
The maximum frequency is taken from Maximum Reference Clamp (01.006)
VM_ACCEL_RATE[MIN] = 0.0
If Ramp Rate Units (02.039) = 0:
VM_ACCEL_RATE[MAX] = 3200.0
Otherwise:
VM_ACCEL_RATE[MAX] = 3200.0 x Maximum frequency / 100.00
VM_DC_VOLTAGE Range applied to DC voltage reference parameters
Units V
Range of [MIN] 0
Range of [MAX] 0 to 1190
Definition
VM_DC_VOLTAGE[MAX] is the full scale DC link voltage feedback (over voltage trip level) for the drive. This level is
drive voltage rating dependent. See Table 10-4
VM_DC_VOLTAGE[MIN] = 0
