Menu 4: Torque and current control
The scaling of the current feedback is based on the rating of the drive as follows:
Over-current trip
Open-loop peak limit
Closed-loop vector, Servo and Regen maximum standard operating
Open-loop maximum standard operating current
Rated drive current
Maximum Normal Duty current rating
Maximum motor rated current
Rated drive current is 1 per unit current and is related to the scaling of the drive current feedback. For most drive sizes the Rated drive current is the
same as the Maximum heavy duty current rating defined by Pr 11.32. The Maximum heavy duty current rating is the maximum value of rated motor
current (defined by Pr 05.07 or 21.07) that can be set for operation with the force vented motor protection characteristic - Pr4.25=0 (see Pr 04.16 for
more details). If the Rated drive current and Maximum heavy duty current rating are the same then the drive uses 1.75 x Maximum heavy duty current
rating for the open-loop peak limit and the maximum standard operating current for closed-loop modes. This is the limit up to which the drive can
control current normally. The current range above this is allowed for current controller overshoot and for additional current feedback pulses
associated with long cable operation. For some of the larger drive sizes the Maximum heavy duty current rating is higher than the Rated drive current,
therefore the potential overload at 1.75 x Rated drive current is reduced.
The motor rated current (defined by Pr 5.07 or Pr 21.07) may be increased above the maximum Heavy Duty current rating up to the maximum Normal
Duty rated current (except for Servo and Regen modes). When the motor rated current is above the maximum Heavy Duty current rating the drive
always provides motor protection scheme that is intended for variable torque applications (see Pr 4.16 on page 97 for more details). The maximum
rated current is the maximum rated current allowed for Normal Duty operation.
Table 5-3 gives the Rated drive current, maximum Heavy Duty current rating and maximum Normal Duty rated current for all drive sizes and voltage
ratings.

UNISP6xxx and UNISP7xxx drive modules can be connected in parallel to make a larger drive. The currents are then defined as follows:
Rated drive current
Rated drive current is the sum of the module currents.
