Table 10-4 Voltage ratings dependant values
VM_SUPPLY_LOSS_LEVEL Range applied to the supply loss threshold
Units V
Range of [MIN] 0 to 1150
Range of [MAX] 0 to 1150
Definition
VM_SUPPLY_LOSS_LEVEL[MAX] = VM_DC_VOLTAGE_SET[MAX]
VM_SUPPLY_LOSS_LEVEL[MIN] is drive voltage rating dependent. See Table 10-4
VM_TORQUE_CURRENT Range applied to torque and torque producing current parameters
Units %
Range of [MIN] -1000.0 to 0.0
Range of [MAX] 0.0 to 1000.0
Definition
VM_TORQUE_CURRENT[MAX] = VM_MOTOR1_CURRENT_LIMIT[MAX]
VM_TORQUE_CURRENT[MIN] = VM_TORQUE_CURRENT[MAX]
VM_TORQUE_CURRENT_UNIPOLAR Unipolar version of VM_TORQUE_CURRENT
Units %
Range of [MIN] 0.0
Range of [MAX] 0.0 to 1000.0
Definition
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
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. 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.
