VM_USER_CURRENT Range applied to torque reference and percentage load parameters with one decimal place
Units %
Range of [MIN] -1000.0 to 0.0
Range of [MAX] 0.0 to 1000.0
Definition
VM_USER_CURRENT[MAX] = User Current Maximum Scaling (04.024)
VM_USER_CURRENT[MIN] = -VM_USER_CURRENT[MAX]
User Current Maximum Scaling (04.024) defines the variable maximum/minimums VM_USER_CURRENT and
VM_USER_CURRENT_HIGH_RES which are applied to Percentage Load (04.020), Torque Reference (04.008) and
Torque Offset (04.009). 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 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.
VM_USER_CURRENT_HIGH_RES
Range applied to torque reference and percentage load parameters with two decimal
places
Units %
Range of [MIN] -1000.00 to 0.00
Range of [MAX] 0.00 to 1000.00
Definition
VM_USER_CURRENT_HIGH_RES[MAX] = User Current Maximum Scaling (04.024) with an additional decimal place
VM_USER_CURRENT_HIGH_RES[MIN] = -VM_USER_CURRENT_HIGH_RES[MAX]
User Current Maximum Scaling (04.024) defines the variable maximum/minimums VM_USER_CURRENT and
VM_USER_CURRENT_HIGH_RES which are applied to Percentage Load (04.020), Torque Reference (04.008) and
Torque Offset (04.009). This is useful when routing these parameters to an analog output as it allows the full scale

range limiting.
