Annual Average Ambient Temperature
Program  Special  Special Parameters
This parameter is used in conjunction with a discrete output terminal setting to
notify the operator of the remaining useful life of critical components of the
ASD system.
With a discrete output terminal set to Part Replacement Alarm (see
on pg. 242) and the calculation derived from the parameter setting, maintenance
scheduling may be enhanced.
Settings:
Under 10° C (50° F) — 60,000 Hours
Under 20° C (68° F) — 60,000 Hours
Under 30° C (86° F) — 60,000 Hours
Under 40° C (104° F) — 60,000 Hours
Under 50° C (122° F) — 40,000 Hours
Under 60° C (140° F) — 2,666 Hours
Rush Current Suppression Replay Activation Time
Program  Special  Special Parameters Rush Relay Current
Activation Time
At system startup, this parameter sets a time-delay for the start of the Rush
Relay activation in an attempt to allow the DC bus voltage to reach the normal
operating level before outputting a signal to the motor.
PTC1 Thermal Selection
Program  Special  Special Parameters PTC1 Thermal Selection
This parameter Enables/Disables the optional external thermal detection circuit
of the Expansion IO Card Option 1. A thermistor is connected from TH1+ to
TH1- of TB3 on the Expansion IO Card Option 1.
Should the thermistor resistance reading fall below 50Ω because of an over-
temperature condition or exceed 3000Ω because of an open circuit an External
Thermal Fault (OH2) will be incurred.
Note: While this parameter is Enabled, the system cannot be restarted
until the thermistor value recovers to the level of 1.8 kΩ from an
over-temperature condition. An Auto-Restart will not be
initiated subsequent to an External Thermal Trip (OH2). A
manual restart will be required in the event of an OH2 trip.
