Programming Parameters
5-66
Parameter 733 – Armature Bridge Type [Arm Bridge Type]
Internal units : None
Programming Terminal units: None
Minimum Value: 0
Maximum Value: 1
Default Value: 1
Description: Selects the type of armature bridge (regenerative or
nonregenerative). The choices are:
0 = Nonregenerative Drive. The armature bridge has 6 SCRs.
1 = Regenerative Drive. The armature bridge consists of 12 SCRs.
Parameter 734 – K Discontinuous [K Discontinuous]
Internal units : 1024 = 400h = Full load current
Programming Terminal units: None
Minimum Value: 33
Maximum Value: 2048
Default Value: 1024
Description: Represents the average value of current feedback at the
cross over point between discontinuous and continuous armature
current. Used to linearize the armature current loop and calculate the
armature current loop gains.
Parameter 735 – KP Armature Loop [KP Armature Loop]
Internal units : 4096 = unity gain
Programming Terminal units: None
Minimum Value: 0
Maximum Value: 32767
Default Value: 710
Description: The proportional gain for the PI regulator in the
armature current loop.
Parameter 736 – KI Armature Loop [KI Armature Loop]
Internal units : None
Programming Terminal units: None
Minimum Value: 0
Maximum Value: 32767
Default Value: 90
Description: The integral gain for the PI regulator in the armature
current loop.
Parameter 737 – KP Field Loop [KP Field Loop]
Internal units : None
Programming Terminal units: None
Minimum Value: 0
Maximum Value: 32767
Default Value: 16384
Description: The proportional gain for the PI regulator in the field
current loop.
