Unidrive M702 User Guide 139
Issue Number: 3
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 the value listed below
Definition
VM_AC_VOLTAGE[MAX] is drive voltage rating dependent. See Table 11-4
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 the value listed below
Definition
VM_AC_VOLTAGE[MAX] is drive voltage rating dependent. See Table 11-4
VM_AC_VOLTAGE[MIN] = 0
VM_ACCEL_RATE Maximum applied to the ramp rate parameters
Units s / 100 Hz, s / 1000 rpm, s / 1000 mm/s
Range of [MIN]
Open-loop: 0.0
RFC-A, RFC-S: 0.000
Range of [MAX]
Open-loop: 0.0 to 3200.0
RFC-A, RFC-S: 0.000 to 3200.000
Definition
Open-loop mode
If Ramp Rate Units (02.039) = 0:
VM_ACCEL_RATE[MAX] = 3200.0
If Ramp Rate Units (02.039) = 1:
VM_ACCEL_RATE[MAX] = 3200.0 x Pr 01.006 / 100.0
VM_ACCEL_RATE[MIN] = 0.0
RFC-A, RFC-S modes
If Ramp Rate Units (02.039) = 0:
VM_ACCEL_RATE[MAX] = 3200.000
If Ramp Rate Units (02.039) = 1:
VM_ACCEL_RATE[MAX] = 3200.000 x Pr 01.006 / 1000.0
VM_ACCEL_RATE[MIN] = 0.000
If the second motor map is selected (Pr 11.045 = 1) Pr 21.001 is used instead of Pr 01.006.
