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 falls 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.

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
) and the calculation derived from the parameter setting, maintenance
scheduling may be enhanced.

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.

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 50
Ω because of an over-
temperature condition or exceed 3000
Ω 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 1.8k
Ω 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.
