Programming Parameters
5-31
Parameter 160 – CEMF Reference [CEMF Reference]
Internal units : 4096 = 1000h = 100% motor CEMF
Programming Terminal units: Percent of full motor CEMF.
Description : This word supplies a n external CEMF reference to the
flux control. This input would be used when it is desired to operate
the field flux control in the CEMF mode of operation. The Drive will
use this input when the CEMF Control Enable bit is set in Flux Mode
Select (Parm 627).
The flux control will use the CEMF reference input as both the
variable in the flux calculation and also as the reference input to the
CEMF regulator. The flux calculation produces a flux command that
is inversely proportional to speed when motor speeds are above the
Field Weakening Speed (Parm 686).
Parameter 161 – Process Trim Reference [Process Trim Ref]
Internal units : 4096 = 1000h = 1pu
Programming Terminal units : None
Description : This is the reference input value for Velocity Trim.
When the Process Trim function has been enabled by setting the Trim
Enable bit in the Logic Command parameter, then this input will be
used by the process trim PI regulator. Process trim will then update
the Process Trim Output (parm 119) based on the value of this input.
5-60Parameter 162 – Process Trim Feedback [Process Trim Fdbk]
Internal units : 4096 = 1000h = 1pu
Programming Terminal units : None
Description : This is the feedback value for Process Trim. When the
Process Trim has been enabled by setting the Process Trim Enable bit
in the Logic Command parameter, then this input will be used by the
process trim PI regulator. Process Trim will then update the Process
Trim Output parameter based on the value of this input.
Parameter 163 – Velocity Indirect 1 [Vel Indirect 1]
Internal units :
Programming Terminal units :
Description : This is the Fast Sink, with its pointer in Parameter 600,
Velocity Parameter Select 1.
Parameter 164 – Velocity Indirect 2 [Vel Indirect 2]
Internal units :
Programming Terminal units :
Description : This is the Fast Sink, with its pointer in Parameter 601,
Velocity Parameter Select 2.
Parameter 165 – Velocity Indirect 3 [Vel Indirect 3]
Internal units :
Programming Terminal units :
Description : This is the Fast Sink, with its pointer in Parameter 602,
Velocity Parameter Select 3.
