Rockwell Automation 1397 DC Drive Firmware 2.xx - Manual (Page 200)

5–90 Programming Parameters
Publication 1397-5.0 — June, 2001
Field
[Field Reference] — P.280
Only used if the Field Current Regulator kit is
installed.
Current reference for the field control loop
field. This is the field current reference when
the drive is not in field economy. Refer to the
[Motor Field Amps] block diagram for
additional information.
Display/Drive Units: AMPS
Parameter Type: Tunable
Group: Field
Minimum Value: 0.00
Factory Default: 0.00
Maximum Value 128.0
[Fld Loop K–Fdbk] — P.281
Only used if the Field Current Regulator kit is
installed.
Gain adjustment for the field feedback. Refer
to the [Motor Field Amps] block diagram for
additional information.
In most cases, this will be set for unity gain,
typically 1.000.
Display/Drive Units:
Parameter Type: Tunable
Group: Field
Minimum Value: 0.90
Factory Default: 1.00
Maximum Value 1.100
[Fld Weak Ld Freq] — P.282
Only used if the Field Current Regulator kit is
installed.
PI block lead frequency of the field control
loop’s armature voltage regulator. Refer to the
[Field Auto Weak] block diagram for
additional information.
Display/Drive Units: RD/S
Parameter Type: Tunable
Group: Field
Minimum Value: 0.00 rad/sec
Factory Default: 0.30 rad/sec
Maximum Value 282.7 rad/sec
[Fld Weaken Kp] — P.283
Only used if the Field Current Regulator kit is
installed.
The proportional gain of the field control
loop’s armature voltage regulator. Refer to the
[Field Auto Weak] block diagram for
additional information.
Parameter Type: Tunable
Group: Field
Minimum Value: 0.10
Factory Default: 0.80
Maximum Value 128.00
[Fld Weaken Level] — P.284
Only available if the Field Current Regulator
kit is installed.
Sets the point at which the field control loop
begins regulating armature voltage and the
field begins to weaken. If IR compensation is
used, the threshold is [Fld Weaken Level]
less [IR Compensation] at rated armature
current. Refer to the Field Auto Weak block
diagram for additional information.
Display/Drive Units: VOLT
Parameter Type: Tunable
Group: Field
Minimum Value: 0
Factory Default: 228
Maximum Value 4095 (4095 corresponds to MOTOR RATED ARM VOLTS)
