VM_SPEED_FREQ_USER_REFS
Units Hz
Range of [MIN] -550.00 to 550.00
Range of [MAX] 0.00 to 550.00
This variable maximum is applied to Analog Reference 1 (01.036), Analog Reference 2 (01.037) and Keypad
Reference (01.017).
The maximum applied to these parameters is the same as other frequency reference parameters.
VM_SPEED_FREQ_USER_REFS [MAX] = VM_SPEED_FREQ_REF[MAX]
However the minimum is dependent on Negative Reference Clamp Enable (01.008) and Bipolar Reference Enable
(01.010).

VM_SUPPLY_LOSS_LEVEL

Range of [MIN] 0 to 1150
Range of [MAX] 0 to 1150
VM_SUPPLY_LOSS_LEVEL[MAX] = VM_DC_VOLTAGE_SET[MAX]

VM_SUPPLY_LOSS_LEVEL[MIN] is drive voltage rating dependent. See Table 11-4
VM_TORQUE_CURRENT

Range of [MAX] 0.0 to 1000.0
VM_TORQUE_CURRENT[MIN] = -VM_TORQUE_CURRENT[MAX]

VM_TORQUE_CURRENT_UNIPOLAR
Units %
Range of [MIN] 0.0
Range of [MAX] 0.0 to 1000.0
VM_TORQUE_CURRENT_UNIPOLAR[MAX] = VM_TORQUE_CURRENT[MAX]
VM_TORQUE_CURRENT_UNIPOLAR[MIN] =0.0
User Current Maximum Scaling (04.024) defines the variable maximum/minimums VM_USER_CURRENT which is
applied to Percentage Load (04.020) and Torque Reference (04.008). This is useful when routing these parameters to
Definition an analog output as it allows the full scale output value to be defined by the user. This maximum is subject to a limit of
MOTOR1_CURRENT_LIMIT or MOTOR2_CURRENT_LIMIT depending on which motor map is currently active.
The maximum value (VM_TORQUE_CURRENT_UNIPOLAR [MAX]) varies between drive sizes with default
parameters loaded. For some drive sizes the default value may be reduced below the value given by the parameter
range limiting.
