Parameter 34 – Velocity Loop PI Output (Vel PI Output) *
Indicates the latest output of the velocity PI regulator.
Parameter Type: View only in Maintenance level
Minimum Value: –8000 rpm
Maximum Value: +8000 rpm
Parameter 35 – Integral Velocity Error (Intg Vel Error) *
The error between the Final Velocity Command (parameter 19) and the
Velocity Feedback (parameter 20) is supplied by this parameter.
Parameter Type: View only in Maintenance level
Minimum Value: –8000 rpm
Maximum Value: +8000 rpm
Parameter 44 – External Torque Reference (Ext Torque Ref) *

from an adapter board (not available at this time). This reference can be
selected by setting the Torque Mode (parameter 133).
Parameter Type: View/modify in Maintenance level
Minimum Value: –300% rated motor current or 2 times drive rating (whichever is less)
Maximum Value: +300% rated motor current
Parameter 45 – Iq (Torque) Current Reference (Iq Current Ref) *
This parameter displays the torque producing current reference.
Parameter Type: View only in all levels
Minimum Value: –300% rated motor current or 2 times drive rating (whichever is less)
Maximum Value: +300% rated motor current
Parameter 46 – Id (Flux) Current Reference (Id Current Ref) *
The flux producing current reference is displayed by this parameter.
Parameter Type: View only in Maintenance level
Minimum Value: 0
Maximum Value: 70% rated motor current
Parameter 47 – IT Protection Limit (IT Protect Lim) *
This parameter displays the amount that the bridge current limit is reduced,
based on the output of an analog circuit which models the thermal
characteristic of the inverter power transistors.
Parameter Type: View only in Maintenance level
Minimum Value: 0
Maximum Value: Drive current rating
Parameter 48 – Bridge Current Limit (Bridge Cur Lim) *
The bridge current limit which is calculated by the drive based on motor
current and drive size (parameters 155 & 3) is displayed by this parameter.
Parameter Type: View only in Maintenance level
Minimum Value: 0 Amperes
Maximum Value: 200% drive rating or 3 times motor rating
