Variable Minimum / Maximum Pairs
The descriptions below define the variable minimum/maximum pairs that can be used with parameters when the VM format bit is set. The variable
minimum and maximum themselves can be dependent on other parameters, or the drive rating or other conditions as defined. The variable minimum
and the variable maximum have a limited range and this is defined for each minimum/maximum pair.

VM_ACCEL_RATE
Description
Maximum applied to the ramp rate parameters
Units
s/100Hz, s/MaxFrequency
Range of [MIN]
0.0
Range of [MAX]
0.0 to 32000.0
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. 32000.0 s/100Hz.
The maximum frequency is taken from
Maximum Reference Clamp
(01.006) if
Select Motor 2 Parameters
(11.045) = 0, or
M2 Maximum Reference
Clamp
(21.001) if
Select Motor 2 Parameters
(11.045) = 1.
VM_ACCEL_RATE[MIN] = 0.0
If
Ramp Rate Units
(02.039) = 0:
VM_ACCEL_RATE[MAX] = 32000.0
Otherwise:
VM_ACCEL_RATE[MAX] = 32000.0 x Maximum frequency / 100.00
Note - Parameter 11.045 is not available on M100/M101 and so only the Motor 1 parameters are relevant.
Identifier
VM_DC_VOLTAGE
Description
Range applied to d.c. voltage parameters
Units
V
Range of [MIN]
0
Range of [MAX]
0 to 1190
VM_DC_VOLTAGE[MAX] is the full scale d.c. link voltage feedback for the drive. This level is drive voltage rating dependent. See the table below.
