8-16 Parameter Table
Parameter 570 – [A> Low Sum RRDH – Process Trim Low Sum
RRDH]
Use: Determines Process Trim Low Sum value dependent upon logic
mode.
Program Terminal Units: RPM
Maximum Value: 0
Minimum Value: -100
Default Value: -20
Description: This parameter specifies the value of Process Trim Low
Sum, Parameter 721, through velocity indirect Parameter 164. This
sets Parameter 721 to a negative value when in logic mode 9, Run
Reverse Dancer High, which allows the Drive to run in reverse at -20
RPM.
Parameter 571 – [A> Low Sum Norm - Process Trim Low Sum
Normal]
Use: Determines Process Trim Low Sum value dependent upon logic
mode.
Program Terminal Units: RPM
Maximum Value: 0
Minimum Value: -100
Default Value: 0
Description: This parameter specifies the value of Process Trim Low
Sum, Parameter 721, through velocity indirect Parameter 164. This
sets Parameter 721 to zero when in any logic mode other than mode 9,
Run Reverse Dancer High. Thus the Drive will not be allowed to run
in reverse with Parameter 571 active.
Parameter 572 – [A > CFG AUX REF – Configuration for
Auxiliary Reference]
Use: Determines I/O configuration based upon application.
Program Terminal Units: None
Maximum Value: 6
Minimum Value: 0
Default Value: 0
Description: This parameter allows the same RTP Unwind drive
hardware to handle slightly different applications. This parameter
establishes whether the emulation speed reference is a frequency
input (USA bit 0=0) or an analog voltage (Europe bit 0=1). Also
whether the Auto slack speed is from a preset value (USA bit 1=0) or
from an external analog source (Asia-Pacific bit 1=1). The other
configuration is whether the drive stops on a full current regen stop
(USA bit 2=0) or follows the decel ramp (Europe bit 2=1).
