V/I Analog Input Broken Wire Detection Level

Program ⇒ Terminal ⇒ Input Special Functions
This parameter is enabled by providing a non-zero value here. This function
monitors the V/I input signal and if the V/I input signal f alls below the level
specified here and remains there for a period of 0.3 seconds or more a trip will
be incurred (E-18).
This value is entered as 0% to 100% of the V/I input signal range.

Annual Average Ambient Temperature

Program ⇒ Special ⇒ Special Parameters
This parameter is use d in conjunction with a d iscrete output termin al setting to
notify the operator of the remaining useful life of critical components of the
ASD system.
With a discrete output term inal set to Part Replacement Alarm (see T ab le 8 on
pg. 241) and the calculation derived from the parameter setting, maintenance
scheduling may be enhanced.
Settings:
1 — Under 10° C (50° F)
2 — Under 20° C (68° F)
3 — Under 30° C (86° F)
4 — Under 40° C (104° F)
5 — Under 50° C (122° F)
6 — Under 60° C (140° F)

Factory Default — Under 30°
Changeable During Run — No

Rush Relay Current Activation Time

Program ⇒ Special ⇒ Special Param eters ⇒ Rush Relay Current
Activation Time
At system startup, this parameter se ts a time-delay for the start of the Rush
Relay activation in an attemp t to allow the DC bus v oltage to reach the n ormal
operating level before outputting a signal to the motor.

PTC1 Thermal Selection

Program ⇒ Special ⇒ Special Param eters ⇒ PTC1 Thermal Selection
This parameter Enables/Disables the optional external thermal detect ion 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 Ext ernal
Thermal Fault (OH2) will be incurred.
Note: While this parameter is Enabled, the system cannot be restarted
until the thermistor value recov ers to the level of 1.8kΩ 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.
Settings:
0 — Disabled
