Programming Parameters
5–41
Logic Testpoint Select
[Logic Tstpt Sel]
Parameter Number 71
Parameter Type Sink
Display Units x
Drive Units None
Factory Default 0
Minimum Value 0
Maximum Value 30
Enums:
This parameter selects which internal loca-
tion in the logic control software will be-
come the testpoint value shown in P70.
The value based upon the select will be
stored in the Logic Tstpnt Data parameter.
The internal locations of the logic control
software accessible based on the select
value are:

23 Stop event – Fault stop command
24 Stop event – Powerup diagnostic status
25 Stop event – Nonconfigurable fault status
26 Stop event – Current Processor Config Fault Status
27 Stop event – Velocity Processor Config Fault Status
28 Stop event – Adapter fault status

Stop Dwell
[Stop Dwell]
Parameter Number 72
Parameter Type Sink
Display Units x.x sec
Drive Units Display units x 10
Factory Default 0.0 sec
Minimum Value 0.0 sec
Maximum Value 10.0 sec
This sets an adjustable dwell time before
the drive disables speed and torque regu-
lators when a stop has occurred.

[Max DB Power]
Parameter Number 77
Parameter Type Sink
Display Units x Watts
Drive Units None
Factory Default 0 Watts
Minimum Value 0 Watts
Maximum Value 30,000 Watts
Maximum Dynamic Brake Temperature
[Max DB Temp]
Parameter Number 78
Parameter Type Sink
Display Units x deg
Drive Units None
Factory Default 50 deg
Minimum Value 50 deg
Maximum Value 700 deg
Dynamic Brake Time Constant
[DB Time Const]
Parameter Number 79
Parameter Type Sink
Display Units x Sec
Drive Units None
Factory Default 10 sec
Minimum Value 10 sec
Maximum Value 600 sec
This parameter defines the power rating
for the optional Dynamic Brake resistor.
This value is used to calculate the per unit
R theta for the resistor.
This parameter defines the Maximum Tem-
perature Rating for the optional Dynamic
Brake resistor. This value is used to estab-
lish setpoints for setting and clearing a
Brake Overtemperature fault condition.
This parameter defines the thermal time
constant for the Optional Dynamic Brake
resistor. This value is used in the brake
resistor thermal model to predict brake
temperature as a function of regenerative
power.
NOTE: Caution should be used
when changing the dwell time
from the factory setting.
Extended dwell times may not be
desirable from a safety standpoint
in some applications.
